I learned in April via a private Thai Monkey King Facebook group that a limited run of colored resin, plain brass, painted brass, and gold-plated brass idols were to be made to raise funds to buy land on which a Great Sage temple would be built in Lam Narai, Lopburi province, Thailand. I procured the services of a local who contacted the religious organization building the temple, “The Equaling Heaven Academy (Altar) of Lam Narai” (Thai: Săm-nák chĕe tiian dtŭua lam-naa-raai, สำนักฉีเทียนตั๋วลำนารายณ์; Ch: Qitian tan Nannalai, 齊天壇南那來), and reserved a statue for me. Once the idols were cast (over several months), they shipped mine and it arrived on August 31st, 2022. Here, I’d like to briefly describe and compare the idol to other statues that I’ve seen or own.
A fiery halo embellished with an inner circle of stylized ruyi-pattern mushrooms sits behind the Monkey King’s head. This shares similarities with a Monkey Buddha statue from a temple in Fujian province, China (fig. 7), the home of his cult. His bald head is adorned with the famous “curlicue-style” golden headband topped with a flaming Cintāmaṇi jewel, as well as a pair of slithering dragons wrapping around the back and sides of his crown. His visage is intense, with eyes opened wide and the corners of his mouth drawn downwards, forming a subtle “w” shape. A line marking the boundary of his forehead, the sides of his face, and just above his chin is slightly raised, giving the impression that he’s wearing a covering over his head and neck. This represents the pink facial patch, either covering the whole face or just a mask around the eyes, that often appears on gilded Monkey King statues in Thailand (fig. 8).

Both arms are bent at the elbow and held out palm up towards the viewer. His left hand holds an immortal peach, while the right cups the handle of a ruyi-pattern scepter resting on his shoulder. The peach is a common element of his iconography all around the world (fig. 9 & 10); however, the scepter imagery seems to be more popular in Southeast Asia. See, for instance, the trinity from the syncretic “Three Teachings” cult of Malaysia and Singapore. Monkey holds the ruyi-scepter in the same manner (fig. 11).

Both are in my personal collection. See also figure twelve below. Fig. 11 – The “Three Teachings” trinity of Southeast Asia (larger version). Take note of Monkey’s ruyi-scepter. Picture originally posted here.
He wears a knotted neckerchief over a war coat with scale-pattern armor on his shoulders and the flap of cloth between his legs, a military girdle at his stomach and waist adorned with a dragon face, scale-pattern armored pants, and war boots with blocky, up-turned toes. His clothing and armor are adorned with various ruyi-pattern mushrooms. The Monkey King’s iconography commonly shows him wearing armor (fig. 12).
Fig. 12 – Detail of a Taiwanese Great Sage statue wearing armor (larger version). Take note of the armored Monkey statue behind him. Also notice that, like figures nine and ten, the lead idol is holding a peach in the left hand. All statues are in my personal collection.
He sits in a traditional dragon chair. More kingly depictions of the Great Sage commonly portray him seated (fig. 12 & 13). But this element is rare compared to the number of statues showing him standing (refer back to fig. 12; see also my other statues here).
Fig. 12 – The idol from figure nine is also shown seated in a dragon chair (larger version). Fig. 13 – The statue from figure ten is seated in a similar chair but replaces the dragon elements with lotuses (larger version).
Infront of the chair is a step on which his boots rest. It’s labeled in Chinese “大聖佛祖” (Dasheng fozu), or “Great Sage Buddha Patriarch“. I show in this article that the phrase is sometimes transliterated into Thai as “ต้าเชิ่งโฝจู่” (Dtâa chêrngfŏh jòo) and “ไต้เสี่ยฮุกโจ้ว” (Dtâi sìia húk-jôh, or just “Tai Sia Huk Chou/Zhou/Jow”). Both the chair and step sit on a rectangular base adorned with simplistic stone lions to his left and right. I haven’t seen lions in any of his other imagery. The front of the base is labeled:
“The Equaling Heaven Academy (Altar) of Lam Narai”.
The reverse of the backrest features a large symbol for “Buddha” (Fo, 佛), and below this (between the back legs) is a cloud and thunder-pattern lined placard reading:
รุ่น-ซื้อที่ดิน – จัดสร้างโดย คณะม้าทรงพระบู๊ตระกลูหลี่ จลพบุรี (คณะศิษย์จัดสร้างถวาย) 2565 (Thai: rûn séu têe din jàt sâang doi ká-ná máa song prá bóo ต rá gloo-lèe jà-lóp bù-ree (ká-ná sìt jàt sâang tà-wăai))
“The Young Generation Buys Land – Created by the Royal Horse Riding Troupe Raklu Li, Lopburi Province (a group of students made an offering), 2022”. 
This Thai statue is a welcome addition to my ever-growing collection of Great Sage idols. It’s certainly the biggest metal Monkey statue that I’ve found so far.
1. Thank you to “Nattida” for transcribing and translating the Thai text for me.
Many people assume that Sun Wukong (孫悟空), the immortal monkey hero from Journey to the West (Xiyouji, 西遊記, 1592, “JTTW” hereafter), is the inspired creation of Chinese author Wu Cheng’en (吴承恩, d. 1582). However, the character is known to predate the standard edition of the novel by several centuries. In this article, I’d like to highlight the oldest known media referencing or depicting Sun Wukong’s antecedent, the “Monkey Pilgrim” (Hou xingzhe, 猴行者). I will discuss a eulogy from an early-12th-century tale and a mid-13th-century set of poems, as well as Buddhist cave art in northern China and a stone pagoda carving from the south, which range from the late-11th to late-13th-centuries. I ultimately suggest that the character appeared around circa 1000 based on his connection to oral literature.
1. Northern China
1.1. Oldest known reference
The character is mentioned in a eulogy from a tale in Zhang Shinan’s (張世南, d. after 1230) Memoirs of a Traveling Official (Youhuan jiwen, 遊宦紀聞, 13th-century). The story follows Zhang the Sage (Zhang sheng, 張聖), a farmer-turned-Buddhist monk who gains the ability to read and predict the future after eating a magic peach bestowed by an immortal. He is later asked to write a eulogy (zan, 讚) in honor of a temple’s newly built revolving sutra case. It reads:
Fresh are the pattra (palm) leaves on which are written the unexcelled (anuttara), vigorous texts, In several lives, Tripitaka went west to India to retrieve them; Their every line, their every letter is a precious treasure, Each sentence and each word is a field of blessing (puṇyakṣetra). In the waves of the sea of misery (duḥkha-sāgara), the Monkey-disciple  presses on, Through the waters of the river that soak its hair, the horse rushes forward; No sooner have they passed the long sand than they must face the trial of the golden sands, Only while gazing toward the other shore do they know the reasons (pratyāya) for being on this shore. The demons (yaksas) are delighted that they might get their heart’s desire, But the Bodhisattva, with hand clasped in respectful greeting, sends them on; Now here are the five hundred and sixty-odd cases of scriptures, Their merit is difficult to measure, their perfection hard to encompass (Isobe, 1977, as cited in Mair, 1989, pp. 693-694).
The tribute references elements that would later appear in The Story of How Tripitaka of the Great Tang Procures the Scriptures (Da Tang Sanzang qujing shihua, 大唐三藏取經詩話, c. late-13th-century), the earliest printed edition of the JTTW story cycle comprising a seventeen-chapter storytelling prompt. These include Xuanzang’s quest to India over several lifetimes, the Monkey Pilgrim coming to his rescue, the tribulations at the river of sand (a nod to Sha Wujing’s precursor), the demons encountered, and heavenly assistance.
Japanese scholar Isobe Akira dates the tale of Zhang the Sage to the late-Northern or early-Southern Song (circa 1127) based on the mention of certain historical figures therein (Mair, 1989, pp. 693-694).
1.2. Oldest known depictions
The oldest depictions of the Monkey Pilgrim and his master appear in a genre of Silk Road Buddhist cave art representing the adoration of the reclining “Moon in the Water Avalokiteśvara (Guanyin)” (Shuiyue Guanyin, 水月觀音).  Different grottoes depict them as small details to the left or right of the much larger Bodhisattva. The pilgrims are always depicted alongside a horse, which is sometimes ladened with sutras.
Wei and Zhang (2019) provide many examples of early art depicting Xuanzang on his quest. Some show him alone, while others portray him with a disciple. This latter figure ranges from human to the Monkey Pilgrim. The problem here is deciding when the first ends and the second begins. Some depictions are heavily degraded, making them ambiguous enough to be either. A prime example comes from Zhao’an Grotto cave no. 3 (c. 1094-1102) at Ansai District, Yan’an Province, China (Yan’an Ansai Zhao’an di 3 ku, 延安安塞招安第3窟) (fig. 1). The rock carving features two sets of figures at the base, two to the left of the Bodhisattva and three to the right. I’d like to begin with the latter. The first of the three figures has what Wei and Zhang (2019) call a “monkey[-like] form” (houxing, 猴形) (fig. 2) (p. 13). But I have three problems with this being a depiction of the Monkey Pilgrim. One, while vaguely simian, the figure is too degraded to be sure. Two, it makes no sense for Monkey to be the first figure when other examples show Xuanzang in the lead. And three, there is no sutra horse. Conversely, the two figures to the left feature a monk standing in the front with elbows bent as if his (missing) hands are pressed in prayer. And behind him is a faceless disciple tending to the horse. Their right arm is bent at the elbow and angled to where their fist might have original been positioned at the chest. Everything else from the left side of the chest up is missing, however (fig. 3).

Fig. 2 (middle) – Detail of the three degraded figures to the right (larger version). Fig. 3 (right) – Detail of the two figures to the left (larger version). Images from Wei & Zhang, 2019, pp. 12-13.
But this side of the carving shares similarities with three late-Xixia dynasty (late-12th or early-13th-century) murals. The first appears in Yulin Cave no. 2 (Yulin di 2 ku, 榆林第2窟) in Gansu Province. The Monkey Pilgrim is seemingly saluting with his right hand and holding the horse reins with his left fist at the chest. This might explain the disciple’s bent elbow in figure three. Xuanzang is shown with hands clasped in prayer similar to the monk from figure three. Both are depicted facing left and standing at the bank of a river separating them from Avalokiteśvara (fig. 4 & 5) (Wei & Zhang, 2019, p. 35).

The second appears in Yulin Cave no. 3 (Yulin di 3 ku, 榆林第3窟). Xuanzang is again worshiping from a riverbank, but this time he is facing right and the subject of adoration is Samantabhadra(fig. 6). We see that the disciple is far more monkey-like in appearance, complete with furry arms. He stands next to the sutra horse with hands clasped in prayer (fig. 7) (Wei & Zhang, 2019, pp. 36).

The third appears in Eastern Thousand Buddha Cave no. 2 (Dong qianfo dong di 2 ku, 東千佛洞第2窟) in Gansu. It contains iconography similar to Yulin Cave no. 2, complete with the Monkey Pilgrim standing next to a horse in a matching “salute and fist over chest” pose (fig. 8-11) (Wei & Zhang, 2019, pp. 38-40). It’s interesting to note that this is one of the oldest depictions of Monkey with his famous golden headband.

Fig. 9 (top right) – An easier to see line drawing of the scene (larger version). Images from Wei & Zhang, 2019, pp. 38-39. Fig. 10 – Detail of Xuanzang and the Monkey Pilgrim (larger version). Image found randomly on the internet. Fig. 11 – A line drawing of master and disciple (larger version). Images from Wei & Zhang, 2019, pp. 39-40.
Additionally, there are two other examples with varying degrees of similarity. The first also comes from the late-Xixia Eastern Thousand Buddha Cave no. 2. Master and disciple are again worshiping the Moon in the Water Avalokiteśvara at a river bank (fig. 12 & 13), but the Monkey Pilgrim instead holds his staff at the ready like a soldier (fig. 14 & 15).

Fig. 15 – A line drawing of master and disciple (larger version). Images from Wei & Zhang, 2019, pp. 40-42.
The second is the earlier Buddha Cave Grotto (c. 1103-1104) at Hejiagou District, Yichuan County, Shaanxi (Yichuan Hejiaguo Foye dong shiku, 宜川賀家溝佛爺洞石窟), which is similar yet different from the above examples. It’s similar in that the master and disciple are again worshiping from the river bank (fig. 16). The Monkey Pilgrim is also depicted with the “salute and fist over chest” posture. And it’s different in that Xuanzang is shown in the lead kowtowing to the Bodhisattva, while a third degraded figure loiters behind the sutra horse (fig. 17) (Wei & Zhang, 2019, pp. 17-18).
Fig. 16 (top) – The complete Moon in the Water Avalokiteśvara carving from the Buddha Cave Grotto (c. 1103-1104) (larger version). Fig. 17 (bottom) – A detail of Xuanzang and the Monkey Pilgrim (larger version). Images from Wei & Zhang, 2019, pp. 17-18.
There are enough similarities shared between the art of Zhao’an Grotto, Yulin Cave, Eastern Thousand Buddha Cave, and Buddha Cave Grotto to suggest that the disciple from figure three “could” be the Monkey Pilgrim. That’s as far as I’m willing to go without more information.
3. Southern China
3.1. Oldest known reference
Writing in the 1250s, the Song poet Liu Kezhuang (劉克莊, 1187-1269) mentioned our hero twice in his work. The first reads:
From one stroke of the brush it was possible to learn the sense of the Śūraṅgama(sūtra), Yet three letters accompanied the presentation of a robe to Dadian [大顛]. To fetch scriptures (it was necessary to) trouble [the Monkey Pilgrim]. In composing verse (the Buddhists?) do not rival He A’shi [鶴阿師] (Dudbridge, 1970, pp. 45-46). 
The poem is openly critical of Buddhism,  showing that the Monkey Pilgrim was so common at this time that he was used in political satire.
And the second uses Monkey as a metaphor to describe the ageing 70-year-old’s failing appearance. It reads:
A back bent like a water-buffalo in the Zi stream [泗河], Hair as white as the silk thread issued by the “ice silkworms”, A face even uglier than [the Monkey Pilgrim], Verse more scanty than even He Heshi [鶴何師] (Dudbridge, 1970, p. 46).
This shows that even by the mid-13th-century, the character’s ugly features were already well-known. This is mirrored in his monstrous description from the 1592 edition.
3.2. Oldest known depiction
The Kaiyuan Temple (Kaiyuan si, 開元寺; est. 686) in the southern Chinese seaport of Quanzhou in Fujian is home to two 13th-century stone pagodas covered in 80 life-size relief carvings of bodhisattvas, arhats, patriarchs, protector deities, and various mythological creatures. The Monkey Pilgrim (fig. 18) figures among them and is located on the northeastern side of the western pagoda’s fourth story. This structure was erected in 1237 (Ecke & Demiéville, 1935, p. 91), dating the carving to around the same time period as the late-Xixia cave murals along the Silk Road in northern China. This gives us incite into how people of different regions viewed the primate hero.
Fig. 18 – The Kaiyuan Temple stone pagoda carving of the Monkey Pilgrim (1237) (larger version). Image found randomly on the internet.
Three things are immediately apparent. One, the pagoda carving gives precedence to the Monkey Pilgrim, with his entire body taking up most of the available space. Xuanzang, who is normally in the lead position, is instead given a tiny corner above his disciple’s left shoulder. He is shown ascending into the heavens on a divine cloud. Two, Monkey is wearing a double “curlicue-style” headband, the motif being associated with protector deities in religious art of this time. And three, he wields a broadsword with a lick of heavenly flame instead of a staff (refer back to fig. 14 & 15). I’ve theorized in this article that (among other indicators) the combination of the headband, the heavenly blade, and Xuanzang’s ascent to paradise designates the Monkey Pilgrim as a protector deity who removes obstacles to enlightenment. If true, his southern persona was elevated in importance from a mere body guard and horse groom (like in northern art) to a hand of the Buddha.
Before continuing, it’s interesting to note that the aforementioned poet Liu Kezhuang was a native of Putian (Ebrey, 2005, p. 95), which neighbors Quanzhou. This means that his unflattering mental image of the Monkey Pilgrim was likely influenced by the Kaiyuan pagoda carving.
4. First appearance?
To my knowledge, these are the oldest known forms of media mentioning or depicting Sun Wukong’s antecedent, but they certainly aren’t the first. We will never conclusively find his “first” appearance. This is not only because a lot of physical media has been lost to the ravages of time, but also because the Monkey Pilgrim was a product of oral storytelling. He was likely given life in urban storytelling stalls (fig. 19 & 20) and nourished by amateur retellings of his adventures at home. Such tales would have predated any artistic depictions or written references. It’s important to remember that oral literature is intangible and ultimately leaves no trace (that is unless it was written down like the 13th-century version). 
The fact that Zhang the Sage’s eulogy (section 1.1) is just a vague list of events suggests that the original storyteller knew his audience was already intimately familiar with the tale and therefore didn’t need more exposition. This further suggests that the JTTW story cycle had already been circulating for some time prior to circa 1127 (as dated by Isobe Akira). The earliest examples of cave art push the Monkey Pilgrim’s existence back to the earliest years of the 12th-century and possibly even to the late-11th-century. Therefore, we can safely conclude that he dates to at least some time in the 11th-century. And since it can take generations for a story to become engrained in the public psyche, the Monkey Pilgrim might even date to the early Song Dynasty (960-1279). This is why I usually cite circa 1000 as a general time frame for the hero’s appearance.
1) The eulogy writes “Monkey Pilgrim” as Hou xingfu (猴行復) instead of the more familiar Hou xingzhe (猴行者).
2) Buswell & Lopez (2014) explain:
The name of this bodhisattva derives from this image’s most characteristic feature: a luminous disk that encircles the bodhisattva and evokes both a nimbus and a full moon, effectively suggesting its power to dispel the darkness of the night. Another connotation is indicated in texts such as the [Mahāprajñāpāramitāśāstra], where the term “moon in the water” connotes that all phenomena are like reflections of the moon on the surface of the water, thereby signifying insubstantiality and impermanence (pp. 813-814).
3) Source altered slightly. I have changed the Wade-Giles to Pinyin.
4) It openly mocks Buddhist philosophy as shallow (“From one stroke of the brush it was possible to learn the sense of the Śūraṅgama (sūtra)). And it references historical tensions between Buddhism and Confucianism by mentioning the monk Dadian (大顛, 732-824) (“Yet three letters accompanied the presentation of a robe to Dadian”). The Buddhist master was an acquaintance of the Confucian official Han Yu (韓愈, 768-824), who had been exiled to southern China for writing a memorial reprimanding the Tang emperor for patronizing Buddhism. Dudgbridge (1970) believes that the reference to the Monkey Pilgrim “ridicules the degrading of [Xuanzang’s] great mission to the west into a story in which the traveller depends on the support of a fantastic monkey” (p. 46).
5) See, for example, the introduction in Dudbridge (1970).

Plucking a handful of hairs from his own body and throwing them into his mouth, he chewed them to tiny pieces and then spat them into the air. “Change!” he cried, and they changed at once into two or three hundred little monkeys encircling the combatants on all sides. For you see, when someone acquires the body of an immortal, he can project his spirit, change his form, and perform all kinds of wonders. Since the Monkey King had become accomplished in the Way, every one of the eighty-four thousand hairs on his body could change into whatever shape or substance he desired (Wu & Yu, 2012, vol. 1, p. 129).
This tactic of transforming chewed up hairs into dozens, hundreds, or even thousands of monkey clones also appears in chapters 3, 5, 21, 35,44, 86, and 90 (A & B) (Wu & Yu, 2012, vol. 1, pp. 132, 165, 172, & 409; vol. 2, pp. 138 & 277; vol. 3, p. 332; vol. 4, pp. 164-165, 168, 219, & 221). But these chewed up hairs can also be transformed into other objects, such as sleep-inducing bugs in chapters 5 and 86, as well as seven kinds of hawks in chapter 72 (Wu & Yu, 2012, vol. 1, p. 165; vol. 3, p. 332; vol. 4, p. 168).
But the novel states that Sun sometimes changes his hair by first blowing on it with his magic “immortal breath” (xianqi, 仙氣). This article will provide a brief survey of this skill and its abilities.
Explicit mentions of the immortal breath show that it can transform hair into:
Yellow-gold rope to replace a magical weapon of the same name (ch. 34) (Wu & Yu, 2012, vol. 2, p. 130).
Gold-plated, red lacquered box to hold a white jade token (ch. 37) (Wu & Yu, 2012, vol. 2, p. 169).
Wrapper to infiltrate a demon’s lair (ch. 41) (Wu & Yu, 2012, vol. 2, pp. 235-236).
Yellow hound to carry away a bogus immortal’s decapitated head (ch. 46) (Wu & Yu, 2012, vol. 2, p. 308).
Hungry hawk to eat a bogus immortal’s entrails (ch. 46) (Wu & Yu, 2012, vol. 2, p. 310).
Group of 30 tigers to scare away monks (ch. 64) (Wu & Yu, 2012, vol. 3, p. 194).
Sleep-inducing insects and lice, fleas, and bedbugs (ch. 71 (A & B) & 84) (Wu & Yu, 2012, vol. 3, pp. 303 & 304; vol. 4, p. 139).
Gold-headed fly to scare a demon king (ch. 75) (Wu & Yu, 2012, vol. 3, p. 366).
Bow drill (comprised of a diamond bit, a bamboo strip, and a cotton string) to drill out of a dangerous magic treasure (ch. 75) (Wu & Yu, 2012, vol. 3, p. 369).
Very thin but long rope to climb out of a monster’s stomach (ch. 76) (Wu & Yu, 2012, vol. 4, p. 3).
Thirty ropes for tying up bandits (ch. 97) (Wu & Yu, 2012, vol. 4, p. 328).
It should be noted, however, that the novel is very inconsistent regarding this ability. The immortal breath is not always used; Sun often just commands the hair to transform or changes it without saying anything, such as in chapters 4, 33, 34 (A, B, & C), 42, 46, 49, 51, 59, 65, 68, 71, and 74 (Wu & Yu, 2012, vol. 1, p. 156; vol. 2, p. 115, 124-125, 237, 301, 305, & 345-346; vol. 3, p. 13, 120, 216, 269, 305, & 358). The “chewing” and “spitting out” of the hair is another example (see above). But one might argue that spitting requires a build of air in the lungs, so by extension, the immortal breath is being used.
This inconsistency is probably due to the standard 1592 edition of Journey to the West coalescing from independent oral stories developed and told over the centuries (see the late-13th-century version of the story, for example). Therefore, some story tellers likely employed the immortal breath, while others did not.
Fig. 1 – “Wukong Blows His Hair” (c. 1882) by Yoshitoshi (larger version).
This immortal breath is also shown capable of transforming the magic iron staff (fig. 2).
Steel file to file through a magic golden ring pinning Monkey’s neck to a column (ch. 34) (Wu & Yu, 2012, vol. 2, p. 129).
Razor to mutilate two lesser demons (ch. 63) (Wu & Yu, 2012, vol. 3, p. 180).
Flag pole to make a pair of magic cymbals stand upright (ch. 65) (Wu & Yu, 2012, vol. 3, p. 216).
Seventy forked weapons to cut the threads of supernatural spider webs (ch. 73) (Wu & Yu, 2012, vol. 3, p. 340).
Nail to prop open a demon’s mouth while Monkey climbs out of their stomach (ch. 83) (Wu & Yu, 2012, vol. 4, p. 113).
Three-pointed drill to make a covert hole in a wardrobe (ch. 84) (Wu & Yu, 2012, vol. 4, p. 139).
As noted above, the novel is inconsistent in this regard. For instance, Monkey changes the staff into a steel drill without blowing on it in chapter 65 (Wu & Yu, 2012, vol. 3, p. 218). Likewise, no breath is used in chapters 46 and 84 when Sun transforms the weapon into razors for shaving heads (Wu & Yu, 2012, vol. 2, p. 305; vol. 4, p. 139).
Monkey can also transform items not in contact with his body. For instance, in chapter 46, he changes a Daoist lad’s clothing from a spring onion white robe into a brown monk’s robe (Wu & Yu, 2012, vol. 2, p. 305). In chapter 78, Sun transforms Tripitaka into his likeness using a mask made from mud:
Pilgrim, too, had little alternative but to flatten the mud and press it on his own face and, after a little while, succeeded in making an apelike mask. Asking the Tang Monk to stand up but without uttering another word, Pilgrim pasted the mask on his master’s face and recited a magic spell. He then blew his immortal breath onto the mask, crying, “Change!” At once the elder took on the appearance of Pilgrim. He was told to take off his own garments and switch clothes with Pilgrim, who made the magic sign and then recited another spell to change into the form of the Tang Monk (Wu & Yu, 2012, vol. 4, p. 47).
Again, the novel is inconsistent regarding external objects. Sometimes Monkey bights his tongue and spits blood out to change said item, such as in chapter 25 (A & B) (Wu & Yu, 2012, vol. 1, pp. 474-475 & 477; vol. 2, p. 303). [1-2] But, again, one could argue that the immortal breath is used as spitting requires a build-up of air in the lungs.
IV. Special abilities
The immortal breath (fig. 3) is also shown to have other special abilities. For instance, in chapter 46, Monkey uses it to heal a gaping wound in his stomach:
With a swagger, Pilgrim walked down to the execution site. Leaning himself on a huge pillar, he untied his robe and revealed his stomach. The executioner used a rope and tied his neck to the pillar; down below, another rope strapped his two legs also to the pillar. Then he wielded a sharp dagger and ripped Pilgrim’s chest downward, all the way to his lower abdomen. Pilgrim used both his hands to push open his belly, and then he took out his intestines, which he examined one by one. After a long pause, he put them back inside, coil for coil exactly as before. Grasping the skins of his belly and bringing them together with his hands, he blew his magic breath on his abdomen, crying, “Grow!” At once his belly closed up completely (Wu & Yu, 2012, vol. 2, p. 309).
The novel implies that Sun’s immortal breath also has the ability to manipulate souls. For example, in chapter 88, Sun uses it in an arcane ritual designed to bestow three human disciples with super human strength. The pertinent section reads:
In a secluded room behind the Gauze-Drying Pavilion, Pilgrim traced out on the ground a diagram of the Big Dipper. Then he asked the three princes to prostrate themselves inside the diagram and, with eyes closed, exercise the utmost concentration. Behind them he himself recited in silence the true sayings of realized immortality and intoned the words of Dharani as he blew divine breaths into their visceral cavities. Their primordial spirits [yuanshen, 元神] were thus restored to their original abodes …
The term “primordial spirits” (yuanshen, 元神) is commonly associated with Buddhahood or enlightenment. In Daoism, it is synonymous with the attainment of immortality via the formation of a “Sacred Embryo” (shengtai, 聖胎), which is forged from spiritual energies over long years of self-cultivation (Darga, 2008). This suggests that Monkey’s immortal breath also grants the disciples some form of immortality. You can read about the entire ritual here.

And in chapter 97, Sun uses the immortal breath to transform an old man’s soul into “ether” for easy transport back to the world of the living:
Pilgrim changed the soul of the squire into ether [qi, 氣] by blowing on him. The ether was stored in his sleeve so that they could leave [Hell] and go back to the world of light together. Astride the clouds, he soon arrived at the Kou house. Eight Rules [Zhu Bajie] was told to pry open the lid of the coffin, and the soul of the squire was pushed into his body. In a moment, he began to breathe once more and revived (Wu & Yu, 2012, vol. 4, p. 339).
The phrase “immortal breath” (xianqi, 仙氣) is missing in the original Chinese, but the ability’s use is understood as the passage mentions Monkey “blowing” (chui, 吹) on the soul.
Various chapters of Journey to the West show that Sun Wukong can use his immortal breath to transform his hair, his magic staff, and items not directly in contact with his body into anything he desires. These range from utilitarian items like files, blades, drills, and ropes to living creatures like insects, birds of prey, dogs, tigers, lesser demons, and even independent copies of himself. It can also change the color and appearance of clothing, as well as magically disguise someone when used in tandem with a mask. The skill’s special abilities include healing and soul manipulation. Evidence suggests that it can restore the “primordial spirit”, granting some form of immortality, as well as transform souls into “ether” for better ease of transport.
The immortal breath, however, is not used consistently throughout the novel. Monkey sometimes chews up and spits out the hair, commands it to change, or simply transforms it without saying anything at all. This inconsistency is likely due to the novel coalescing from independent oral stories developed and told over the centuries.
1) Thank you to Irwen Wong for reminding me of this.
If you were to ask someone to name Sun Wukong‘s master, those familiar with Journey to the West (Xiyouji, 西遊記, 1592) would probably say the Tang monk Tripitaka (Tang Sanzang, 唐三藏). But many forget that the cleric is actually his second master. His first, the Patriarch Subodhi (Xuputi zushi, 須菩提祖師; a.k.a. “Patriarch Puti / Bodhi“, Puti zushi, 菩提祖師), is rarely brought up in conversation. But this wise old man / elderly martial arts master archetype is the source of the Monkey King’s divine longevity, magical skills, and fighting prowess. He therefore deserves his own article. I’ve already written several pieces mentioning him, so I’ve decided to combine everything (including new material) onto a single page.
This article describes his origins, story in the novel, and description; the location, description, and the meaning of the name of his mountain home; his school uniform; how he names his students and why the Monkey King is called Sun Wukong; his religious, magical, and martial arts curriculum, including tests of spiritual intelligence; and his spiritual powers. Despite his common portrayal as a Daoist immortal (xian, 仙), the novel stresses a connection to Buddhism. I ultimately suggest that the Patriarch Subodhi is in reality a bodhisattva (pusa, 菩薩), albeit one with Daoist leanings.
Subodhi is based on Subhūti (Xuputi, 須扶提 / 須浮帝 / 蘇補底 / 蘇部底) (fig. 1),  one of the ten principle disciples of the Gautama Buddha. He plays an understated role in the original Pāli canon of Theravāda Buddhism, being recognized by the Buddha as the most accomplished in meditating on the concept of “loving-kindness” (Pāli: Metta; Sanskrit: Maitri), or wishing for the happiness of others (Buswell & Lopez, 2014, pp. 861-862; Osto, 2016, pp. 126-127). On the contrary, Subhūti plays a much larger role in Prajñāpāramitā texts of Mahāyāna Buddhism in which he is famed for contemplating “emptiness” (Pāli: suññatā; Sk: śūnyatā; Ch: kong, 空), a subject with textual interpretations ranging from ridding oneself of sexual desires to realizing the truth of the illusionary nature of Saṃsāra (Buswell & Lopez, 2014, pp. 872; Osto, 2016, p. 126). Because of this, he is also known in Chinese as the “One who expounded vacuity [emptiness]” (Kongsheng, 空生) (Soothill & Hodous, 1937/2014, p. 277). In fact, Osto (2016) suggests that Subhūti was secretly a bodhisattva, reasoning: “How else would he have the necessary insight to understand the profound and paradoxical philosophy of emptiness (śūnyatā) as it is found in these texts?” (p. 128). 
Fig. 1 – A detail of Subhūti from a woodblock frontispiece appearing in an 868 CE copy of the Diamond Sutra (larger version). This document is the oldest known dated printed book in the world (full woodblock).
Shao (2006) suggests that Subodhi was modeled on the historical disciple “to evoke a scriptural tradition that identifies Subhūti as the Buddhist at his best, one having the spiritual and intuitive approximation to ’emptiness’ … that the Chan [Zen] Buddhists value tremendously” (p. 723). He continues:
Is it then possible that what the novelist tried to highlight with Subhūti’s name was his reputation as the epitome of emptiness? We can certainly find ample textual evidence to support this line of thinking. Although Monkey’s Taoist realization is worthy of heaven, his Buddhist given name Wukong, or Awaken to Emptiness, obviously represents Subhūti’s Buddhist heritage, for the name is exactly what distinguishes Subhūti in the Buddhist tradition. What gives proof of the power and vitality of this bequest is the fact that “emptiness” constitutes the core of Monkey’s religious being (Shao, 2006, p. 724).
It should be noted that the complete Chinese name Xuputi (須菩提) is only used once in the novel to refer to the Patriarch (see here), while Puti (菩提) is used at least three times (see here). This is interesting as the latter term is a transliteration of bodhi (Pāli / Sk: “awakening” or “enlightenment”), an important concept in Buddhism in which one discovers the Four Noble Truths, thereby achieving enlightenment and freeing themself from the cycle of rebirth (Buswell & Lopez, 2014, p. 129). Therefore, the novel positions the Patriarch as a means to or even embodiment of enlightenment. This is fitting given Osto’s (2016) suggestion above that the historical Subhūti was a bodhisattva, “a ‘being’ (sattva) intent on awakening (bodhi) who has aroused the aspiration to achieve buddhahood” (Buswell & Lopez, 2014, p. 129). More on this below.
2. The literary teacher
2.1. His story
Subodhi is introduced by name in chapter one when a woodcutter tells the Monkey King about the sage and the location of his mountain home. He learns that the Patriarch “has already sent out innumerable disciples” and that at present “there are thirty or forty persons who are practicing austerities with him” (Wu & Yu, 2012, vol. 1, p. 112). After a quick exchange with an immortal lad at the front door, the Stone Monkey is led to a hall where Subodhi is lecturing to a group of “lesser immortals” (xiaoxian, 小仙). The Patriarch asks for his name and the location of his home but becomes upset as he believes Monkey is lying about his ten year journey from afar. However, after being assured of the truth and hearing of the miraculous stone birth, Subodhi officially accepts the primate as a disciple, giving him the religious name Sun Wukong (孫悟空, “Monkey Awakened to Emptiness”).
In the opening of chapter two, the Patriarch has his immortal students tutor Monkey in menial tasks like fetching firewood and water, tending the garden, and cleaning the monastery grounds, as well as provide lessons on human language and etiquette, calligraphy, scripture reading, and minor ritual procedures like incense burning. Seven years later, Subodhi notices Sun jumping around in excitement as the primate listens to his lecture. He thereafter offers to teach Monkey a number of skills, but the latter refuses multiple times since they won’t lead to immortality. This rejection makes the Patriarch visually upset, leading him to strike Sun on the head three times with a ruler and then walk away with his hands behind his back. His senior religious brothers chastise him for angering their master, but, due to his spiritual intelligence, Sun knows that the admonishment was really secret code. He later enters Subodhi’s room at the third watch (three hits) using a back door (hands behind back), and it is there where the teacher reveals the secret of immortality in a flowery poem.
After Monkey successfully attains eternal life three years later, the Patriarch teaches him the 72 transformations in order to hide from heaven-sent punishment slated to destroy him. In addition, he teaches the cloud-somersault, a method of super fast flight. Sun’s religious brothers are amazed at his attainments and request that he display his power of transformation by changing into a pine tree. The resulting applause greatly disturbs Subodhi, who sends the others away before reprimanding and expelling his disciple under the pretense of saving Monkey’s life from those who would harm him to learn his heavenly secrets. But before Sun has a chance to leave, his master threatens him with everlasting torment in the underworld if he ever reveals that the Patriarch had been his tutor. Monkey promises never to speak his name. This is the last time that Subodhi is seen in the story, but he is referenced two more times in later chapters (see section 3.4 below).
2.2. Allusions to Buddhist masters
Shao (1997) writes that Subodhi hitting Monkey on the head three times—a coded message for receiving secret teachings in the Master’s room at the third watch—is likely based on two episodes from the life of Huineng (惠能, 638-713), the Sixth Chan (Zen) Patriarch:
According to [the Platform Sutra], Huineng was pounding grain when Hongren [the 5th Chan Patriarch] came in, “hit on the mortar three times with his stick and then left” (以杖击碓三下而去). The non-verbal message occurred to the young man as a piece of intuition. By the third watch he arrived dutifully at the master’s chamber where Hongren passed the secret Dharma by way of enlightening him on [the Diamond Sutra], behind a raised cassock used to protect them from the intrusion of prying eyes. The other source is Caoxi dashi biezhuan 曹溪大师别传 (An Alternative Biography of the Great Master From Caoxi) in which Huineng hit Shenhui … a few times, seemingly annoyed by the insolence of his disciple’s clever repartee. But it was to none other than Shenhui that he imparted the secret Dharma—in the middle of the night, and with a similar group of dumb disciples who had seen nothing but impudence in Shenhui (pp. 60-61).
The allusion to Hongren and his use of the Diamond Sutra is apt as the historical Subhūti plays a large part in the scripture. His questions fuel the lesson, with the “Buddha’s reply constitut[ing] the body of the sutra” (Watson, 2010, p. 72).
Therefore, the aforementioned episodes associate the Patriarch with two enlightened Chan masters and their secret, unorthodox transmission of the Dharma, supporting his connection to Buddhism.
The novel includes a third allusion to Huineng. This will be discussed in section 4.3 below.
2.3. His description
The novel never gives an overt description of Subodhi’s features or dress. This ambiguity makes him a blank slate onto which anyone’s personal vision can be written. But there are a few references to his stately, awe-inspiring presence. A poem in chapter one reads:
A Golden Immortal of Great Awareness and of great ken and purest mien,
Master Bodhi, whose wondrous appearance like the West
Had no end or birth by work of the Double Three.
His whole spirit and breath were with mercy filled.
Empty, spontaneous, it could change at will,
His Buddha-nature able to do all things.
The same age as Heaven had his majestic frame.
Fully tried and enlightened was this grand priest (Wu & Yu, 2012, vol. 1, p. 114). 
Numerous elements from this poem require explanation. “Golden Immortal of Great Awareness” (Dajue jinxian, 大覺金仙) was a title bestowed on the Buddha by Song Emperor Huizong in 1119 in order to bring Buddhism under the banner of Daoism (Eskildsen, 2008, p. 43). “Wonderous appearance like the West” (Xifang miaoxiang, 西方妙相) compares the splendor of his person to the Western Pure Land (Sk: Sukhāvatī; Ch: Xifang jingtu, 西方淨土) of the Amitābha Buddha. “No end and no birth” (busheng bumie, 不生不滅) refers to his eternal life free from the wheel of reincarnation, which is thanks to his mastery of the “Double Three” (Sansan xing, 三三行). Yu (Wu & Yu, 2012) explains that this term likely refers to the “three samādhis“, a high-level meditation technique which focuses on the Buddhist philosophical concepts of emptiness, no appearance, and no desires (Wu & Yu, 2012, vol. 1, p. 507 n. 16). “Empty” (kong, 空) in the next line of course refers to Subodhi’s constant meditations on emptiness. “Buddha-nature” (Sk: tathāgatagarbha, lit: “womb of the tathāgata“; Ch: Zhenru benxing, 真如本性; a.k.a. Rulai zang, 如來藏) is “the potential to achieve buddhahood that, according to some Mahāyāna schools, is inherent in all sentient beings” (Buswell & Lopez, 2014, p. 897). This is an open reference to the Buddho-Daoist philosophy of the Southern Quanzhen School Patriarch Zhang Boduan (張伯端, mid to late-980s-1082), which greatly influenced Journey to the West. He believed that in order to become a true transcendent (xian, 仙), one had to achieve both the Daoist elixir of immortality and Buddha-nature (Shao, 1997; 2006). This dual achievement thus signifies that Subodhi is a celestial of the highest order. His “majestic” (or stately) body (zhuangyan ti, 莊嚴體) is said to have the “same age as heaven” (yutian tongshou, 與天同壽), a phrase used in the novel to denote the endless longevity of such divine beings (see here). The last line notes that he is a fully “enlightened” (mingxin, 明心; lit: “illuminous heart-mind”) master. Taken together, the allusions to Buddhas, the Western paradise, emptiness, and enlightenment speak to Subodhi’s identity as a Buddhist deity. And given his association with bodhi (awakening), I suggest that he is in fact a bodhisattva like his namesake, albeit one with Daoist leanings.
A Daoist bodhisattva may seem paradoxical, but this concept comfortably fits into the syncretic worldview espoused in late-Ming literature. For example, three well-known bodhisattvas are depicted as former high-ranking immortals in Investiture of the Gods (Fengshen yanyi, 封神演義, c. 1620). These include Guanyin (觀音) as “Person of the Way, Compassionate Ferry” (Cihang daoren, 慈航道人) (fig. 2), Mañjuśrī (Wenshu, 文殊) as the “Dharma-Spreading Heavenly Master of Outstanding Culture” (Wenshu guangfa tianzun, 文殊廣法天尊), and Samantabhadra (Puxian, 普賢) as the “Perfected Man of Universal Virtue” (Puxian zhenren, 普賢真人). Together, they later convert to Buddhism and become disciples of the Buddha (hou xing shimen, chengyu fojiao, 後興釋門，成于佛教) at the end of chapter 83.

2.4. Ancient depiction
The standard 1592 edition of Journey to the West was originally published with a series of quaint woodblock prints. One features an image of the Patriarch, depicting him as a robed master holding a palace fan while seated in an ornate chair. He wears a guan-cap and has a kind face with airy whiskers and hints of large-lobed ears (fig. 3 and 4).

The novel remarks on the beauty of the mountain as Monkey walks through a forest to the school’s front entrance:
Mist and smoke in diffusive brilliance,
Flashing lights from the sun and moon,
A thousand stalks of old cypress,
Ten thousand stems of tall bamboo.
A thousand stalks of old cypress
Draped in rain half fill the air with tender green;
Ten thousand stems of tall bamboo
Held in smoke will paint the glen chartreuse.
Strange flowers spread brocades before the door.
Jadelike grass emits fragrance beside the bridge.
On ridges protruding grow moist green lichens;
On hanging cliffs cling the long blue mosses.
The cries of immortal cranes are often heard.
Once in a while a phoenix soars overhead.
When the cranes cry,
Their sounds reach through the marsh to the distant sky.
When the phoenix soars up,
Its plume with five bright colors embroiders the clouds.
Black apes and white deer may come or hide;
Gold lions and jade elephants may leave or bide.
A Blessed Land [Fudi, 福地] to be seen in spirit:
It has the true semblance of Paradise (Wu & Yu, 2012, vol. 1, pp. 112-113).
“Blessed lands” (Fudi, 福地) are thought to be “earthly paradises that do not suffer from floods, wars, epidemics, illnesses, old age or death” (Miura, 2008, p. 368). Daoism recognizes 72 Blessed Lands, each with their own documented name and location (Miura, 2008, p. 371).
3.2. Cave description
Once Sun is invited inside, the cave is described as having “rows and rows of lofty towers and huge alcoves, of pearly chambers and carved arches”, as well as “innumerable quiet chambers and empty studios” (Wu & Yu, 2012, vol. 1, p. 114). The hall where Subodhi gives his lessons is said to be centered around his “green jade platform” (yaotai, 瑤臺) (Wu & Yu, 2012, vol. 1, p. 114). This kind of terrace is often associated with the immortal lands of Mount Kunlun (Santangelo, 2013, p. 604 n. 5).
3.3. Buddho-Daoist metaphor
The names of the cave and mountain reference the philosophical concept of the “heart-mind” (xin, 心), the center of spiritual intellect, no less than three times. As I explain in this article, the name “slanted moon and three stars” is a literal description of the Chinese character for the heart-mind (fig. 5). “Spirit Tower/platform” (lingtai, 靈臺) is used in Daoist literature to refer to the heart-mind, more specifically the middle elixir field (zhong dantian, 中丹田) around the heart, which is considered the seat of the spirit. During internal alchemical meditation, the spirit is directed from here, along with other energetic substances from elsewhere, into the “square inch” (fangcun, 方寸). This too is a Daoist reference to the heart-mind, more specifically the lower elixir field (xia dantian, 下丹田) around the abdomen, the storehouse of vital energies. The synergy of these energies is thought to bolster the body and bring about immortality. Therefore, a more accurate translation of Patriarch Subodhi’s home, which takes into account the veiled Daoist meanings, would be “Cave of the Slanted Moon and Three Stars on the Mountain of Spiritual Heart and Elixir Mind”.
Fig. 5 – The Chinese character for heart-mind (xin) literally looks like a crescent moon surmounted by three stars. Original image found here.
At the same time, this triple emphasis on the heart-mind references Monkey’s role in the novel as the “Mind Monkey” (xinyuan, 心猿), a Buddhist concept denoting the disquieted thoughts that keep man trapped in Saṃsāra. Evidence for this includes the titles for chapters seven (“From the Eight Trigrams Brazier the Great Sage escapes; / Beneath the Five Phases Mountain, Mind Monkey is still”) and fourteen (“Mind Monkey returns to the Right; / The Six Robbers vanish from sight”). Also, a poem in chapter seven reads: “An ape’s body of Dao weds the human mind. / Mind is a monkey—this meaning’s profound” (yuanhou dao ti renxin / xin ji yuanhou yisi shen, 猿猴道體配人心 / 心即猿猴意思深) (Wu & Yu, 2012, p. 190). 
Therefore, the name of the Patriarch’s mountain home is a double metaphor for Daoist alchemical and Buddhist philosophical concepts.
3.4. References in later chapters
Monkey references Subodhi and his mountain home twice in the novel. He recites a biographical poem in chapter 17 in which he states:
Seedlings of herbs I plucked on Spirit Tower Mountain. / There was in that mountain an old immortal. / His age: one hundred and eight thousand years! / He became my master most solemnly / And showed me the way to longevity (Wu & Yu, 2012, vol. 1, p. 352). 
In another biographical poem from chapter 67, he states: “I bowed to the Patriarch of Spirit Tower and Square Inch / and perfected with him the martial arts” (Wu & Yu, 2012, vol 3, p. 243). These statements are veiled admissions of studying alchemical and combat arts under the Sage, thereby not revealing his true master’s identity (as promised in chapter two).
The location of this mountain is revealed in the first conversation between Monkey and Subodhi. After hearing of Sun’s travels, the Patriarch asks:
[H]ow is it that you mention the East Purvavideha Continent? Separating that place and mine are two great oceans and the entire region of the Southern Jambudvipa Continent. How could you possibly get here? (Wu & Yu, 2012, vol. 1, p. 114).
The world of Journey to the West is modeled on Hindo-Buddhist cosmic geography, which places the Eastern Purvavideha Continent (Sk: “Surpassing the body”; Ch: Dongsheng shenzhou, 東勝神洲), the Southern Jambudvipa Continent (Sk: “Rose-Apple”; Ch: Nanshan buzhou, 南贍部洲), the Western Godaniya Continent (Sk: “Using Cattle”; Ch: Xiniu hezhou, 西牛賀洲), the Northern Uttarakuru Continent (Sk: “Unpleasant Sound”; Ch: Beiju luzhou, 北俱盧洲) around the four respective faces of Mount Sumeru (Ximi shan, 須彌山; Miaogao shan, 妙高山), a giant mountain that serves as the axis mundi of the cosmos, as well as the abode of assorted gods and sages (Buswell & Lopez, 2014, p. 869) (fig. 6). While said geography traditionally associates Southern Jambudvipa with India, or the known world to the ancient people of South Asia (Buswell & Lopez, 2014, p. 377), the novel places the “Land of the East” (Dongtu, 東土) (i.e. China) within the continent and associates India with Western Godaniya (Wu & Yu, 2012, pp. 204-205). Therefore, Subodhi’s mountain is located in India, further strengthening his link with Buddhism.
Fig. 6 – A diagram showing a bird’s-eye view of Hindo-Buddhist cosmic geography as presented in Journey to the West. Adapted from Buswell & Lopez, 2014, p. xxix (larger version).
Upon returning to the Mountain of Flowers and Fruit from Subodhi’s school in chapter two, the novel describes Sun Wukong’s uniform through the voice of a monster imp: “He is bare-headed, wears a red robe [hongse yi, 紅色衣] with a yellow sash [huang tao, 黃絛], and has a pair of black boots [wu xue, 烏靴] on” (Wu & Yu, vol. 1, p. 127). The “red robe” is vague, but a poem in chapter one states that the immortal lad who invited Monkey into the cave was wearing “[a] wide robe with two sleeves of wind” (kuanpao liangxiao feng, 寬袍兩袖風). This probably references the large, open arms of the zhiduo robe (直裰; a.k.a. haiqing, 海青), which is known colloquially in English as “Buddhist monk” or “Taoist monk” robes (fig. 7).
Fig. 7 – A zhiduo robe with large sleeves (larger version). Image found here. Imagine this robe red, with a yellow sash at the waist.
4.2. Student names
Subodhi is shown to have 12 generation names (zibei, 字輩) used to name the generational cohorts of his religious lineage.
Jue (覺) (Wu & Yu, 2012, p. 115).
Three of the listed names, Zhi (智), Yuan (圓), and Jue (覺), were historically used in Daoism. 
Monkey is part of the tenth generation (Wu & Yu, 2012, p. 115). This means that all of Subodhi’s students taken in around the same time would all have Wu (悟) in their name.
The novel explains in detail why Subodhi names his primate disciple Sun Wukong, tying it to Buddho-Daoist philosophy:
The Patriarch laughed and said, “Though your features are not the most attractive, you do resemble a pignolia-eating monkey (husun [猢猻]). This gives me the idea of taking a surname for you from your appearance. I intended to call you by the name Hu [猢]. If I drop the animal radical [犭] from this word, what’s left is a compound made up of the two characters, gu [古] and yue [月]. Gu means aged and yue [“moon”] denotes feminine yin energy [陰], but aged yin cannot reproduce. Therefore, it is better to give you the surname of Sun [猻]. If I drop the animal radical from this word, what we have left is the compound of zi [子] and xi [系]. Zi means a boy and xi means a baby, and that name exactly accords with the fundamental Doctrine of the Baby Boy [Ying’er zhi benlun, 嬰兒之本論]. So your surname will be ‘Sun.'”
[After explaining the generational names] “You will hence be given the religious name ‘Aware of Emptiness’ (wukong [悟空]). All right?” (Wu & Yu, 2012, vol. 1, p. 115).
Yu (Wu & Yu, 2012) explains: “The Baby Boy is none other than the ‘holy embryo or shengtai 聖胎,’ the avatar of the realized state of immortality in the adept’s body” (p. 86). Daoist doctrine dictates that the “Three Treasures” (Sanbao, 三寶) of semen (jing, 精), breath (qi, 氣), and spirit (shen, 神) be combined to create a holy embryo. The third stage of this internal alchemical process involves the nurturing of said embryo to maturation with spiritual energies and eventually guiding it upwards and out the Heavenly Gate (Tianguan, 天關), or the top of the crown. This results in a fledgling immortal spirit body that must be trained over an additional three year period in which it learns to travel far and wide apart from the physical vessel (Kohn, 2008, pp. 179-180). Therefore, Sun (孫) not only references the primate disciple’s appearance but also his Daoist immortality.
“Wukong” (悟空) combines “Emptiness” (Kong, 空) with “Awakening”, Wu (悟) being “one of the common Chinese translations for the Sanskrit term bodhi (awakening)” (i.e. the bodhi of Subodhi) (Buswell & Lopez, 2014, p. 998). Awakening takes two forms in Chan Buddhism: “instant” (dunwu, 頓悟) and “gradual” (jianwu, 漸悟). The former involves the sudden manifestation of inherent Buddha-nature (see section 2.3), while the latter involves compounding realization, often over a long period of purification (Buswell & Lopez, 2014, p. 998; see also pp. 273 and 384-385). As explained in section 1, bodhi involves realizing the Four Noble Truths, thereby achieving enlightenment and freeing oneself from the cycle of rebirth. Therefore, Wukong references said enlightenment.
Given the above information, another translation for Sun Wukong would be “Immortal Enlightened By Emptiness”. This shows that Monkey’s name incapsulates his story arc: attaining divine longevity in the beginning and ascending to Buddhahood at the end. This, again, is an open reference to the highly influential Buddho-Daoist philosophy of Zhang Boduan (see section 2.3).
4.3. Tests of spiritual intelligence
The Patriarch first offers to teach Monkey a selection of skills from the 360 “Side Gates” (bangmen, 傍門; a.k.a. pangmen, 旁門), noting that they will “result in illumination” (zhengguo, 正果; lit: “right fruit”) (Wu & Yu, 2012, vol. 1, p. 117). The skills include:
Method gate (Shuzi menzhong, 術字門中) – “[C]onsists of summoning immortals and working the planchette, of divination by manipulating yarrow stalks, and of learning the secrets of pursuing good and avoiding evil” (Wu & Yu, 2012, vol. 1, p. 117).
Dissemination gate (Liuzi menzhong, 流字門中) – “[I]ncludes the Confucians, the Buddhists, the Daoists, the Dualists, the Mohists, and the Physicians. They read scriptures or recite prayers; they interview priests or conjure up saints and the like” (Wu & Yu, 2012, vol. 1, p. 117).
Silence gate (Jingzi menzhong, 靜字門中) – “To cultivate fasting and abstinence … quiescence and inactivity, meditation and the art of cross-legged sitting, restraint of language, and a vegetarian diet. There are also the practices of yoga, exercises standing or prostrate, entrance into complete stillness, contemplation in solitary confinement, and the like” (Wu & Yu, 2012, vol. 1, pp. 117-118).
Action gate (Dongzi menzhong, 動字門中) – “[G]athering the yin to nourish the yang, bending the bow and treading the arrow, and rubbing the navel to pass breath. There are also experimentation with alchemical formulas, burning rushes and forging cauldrons, taking red lead, making autumn stone, and drinking bride’s milk and the like” (Wu & Yu, 2012, vol. 1, p. 118).
However, the Side Gates, which number 3,600 in Daoist literature, were historically considered “unorthodox training methods of limited benefit” (Eskildsen, 2019, p. 43). This shows that Subodhi is testing his disciple to see if he will fall for studying lesser arts. But Sun passes by refusing to learn them.
Another test takes place when Monkey visits his master’s room at the third watch to receive secret teachings. Shao (2006) explains that, once again, the novel alludes to the Sixth Chan Patriarch Huineng:
[Monkey] sets the stage for a striking display of his unusually profound insight when he announces his intentions to become an immortal. This provokes Subhuti to issue him a challenge by refusing to teach him, for he is “some what different from other people.” Monkey may not realize that the master is trying to gauge his spiritual power, but he rises to the occasion with a genuine clarity of vision: “I have a round head pointing to Heaven, and square feet walking on Earth. Similarly, I have nine apertures and four limbs, entrails and cavities. In what way am I different from other people?”
[W]e may look to Huineng’s story from which Monkey garners meaning. No doubt, Monkey’s inspired cleverness is modeled on Huineng’s reply to Hongren, the fifth patriarch of Chinese Chan Buddhism, in Huineng’s Tanjing (The Platform Sutra). When Huineng announces his intentions to become a Buddha, Hongren pounces upon him with a poignant reminder that he is “from Lingnan,” a “barbarian,” and therefore cannot become a Buddha. Huineng refuses to be intimidated, however. He holds his own with an unparalleled depth of insight about Buddha-nature: There may be “northern and southern men,” but “the Buddha nature fundamentally has no north or south.” Surely Monkey’s phrasing, his unusual insightfulness, and the quickness and aplomb with which he rises to the challenge are reminiscent of Huineng… (pp. 719-720).
Monkey clearly passes this test, for his insightful reply convinces the Patriarch to teach him the secret of eternal life.
Subodhi no doubt uses such examinations to filter out unsuitable candidates, allowing only the brightest individuals to become his inner disciples.
4.4. Overtly stated curriculum and tools
The novel specifically mentions Subodhi offering or teaching Monkey the following concepts:
1) Chinese philosophy – A poem describes one of these lectures with esoteric imagery. Most importantly, a section states: “For a while he lectured on Dao [道] / For a while he spoke on Chan [禪] / To harmonize the Three Parties [Sanjia, 三家] is a natural thing” (Wu & Yu, 2012, vol. 1, p. 116).
The “Three Parties” refer to the Ming syncretic philosophy of the “Three Teachings” (Sanjiao, 三教), which combines elements from Buddhism, Daoism, and Confucianism. This shows that his disciples are given a well-rounded religious education, which explains why Sun is competent even in Buddhist scripture. 
Also, during his lectures on philosophy, Subodhi is said to wield a “Precepts ruler” (jiechi, 戒尺), which he uses to admonish his students (Wu & Yu, 2012, vol. 1, p. 118). Such a device figures among the tools of Buddhism (Leong, 2001, p. 49).
2) Secret of Immortality – Breathing exercises designed to absorb yang energy during prescribed times (after midnight and before noon), the retention of chaste semen and transformation into qi energy, and the purification and circulation of the resulting spiritual energy throughout the body.
These internal methods are passed onto Monkey in secret via a flowery poem chocked full of alchemical imagery. It ends with the line, “When that’s done, be a Buddha or immortal at will!” (Wu & Yu, 2012, vol. 1, p. 120). Combined with his syncretic philosophy, this suggests that the Patriarch offers his students more than one spiritual path to divinity.
3) Transformations – A series of oral formulas that allow the user to change their body into any person, animal, or object. Two forms are offered: the 72 changes of the “Multitude of Terrestrial Killers” (Disha shu, 地煞數) and the 36 changes of the “Multitude of the Heavenly Rectifiers” (Tiangang shu, 天罡數) (Wu & Yu, 2012, vol. 1, p. 122). 
Subodhi teaches this skill to Monkey with the expressed purpose of helping him hide from three calamities of cosmic lightning, fire, and wind sent by heaven to destroy immortals for defying fate and achieving eternal life. But beyond the power of metamorphosis, the novel implies that the ability also grants the user multiple lives (similar to a video game), which might serve as a buffer against the calamities. For example, in chapter 41, after Sun passes out from Red Boy‘s fiery attack, Zhu Bajie reassures everyone by saying: “If he is capable of seventy-two transformations, he has seventy-two lives” (Wu & Yu, 2012, vol. 2, p. 232). Also, in chapter 46, Monkey magically regrows his head after being non-fatally beheaded in a contest of magical skill. Sha Wujing remarks: “If he knows seventy-two ways of transformation, … he may have altogether seventy-two heads!” (Wu & Yu, 2012, vol. 2, p. 308). In addition, while not directly related to the primate hero, the Bull Demon King is said in chapter 61 to also know the 72 changes (Wu & Yu, 2012, vol. 3, p. 148). He uses the extra lives to survive being beheaded by Prince Nezha a number of times:
[Nezha] leaped onto the bull’s back and brought his monster-cleaving sword down on the bull’s neck: the bull was beheaded at once. Putting away his scimitar, the devaraja was about to greet [Sun Wukong] when another head emerged from the torso of the bull, his mouth belching black air and his eyes beaming golden rays. [Nezha] lifted his sword once more and cut off the bull’s head; as soon as it dropped to the ground, another head came out. It went on like this more than ten times. At last, [Nezha] took out his fiery wheel and hung it on the Bull’s horn. The wheel at once started a great blaze of true immortal fire, which burned so fiercely that the bull began to growl and roar madly, shaking his head and wagging his tail (Wu & Yu, vol. 3, p. 160). 
This agrees with the connection between transformation and immortality in Daoism. Robinet (1979) explains that gods and saints are portrayed in Daoist literature as being in constant flux, changing with the seasons, taking on different guises and titles, disappearing and reappearing, never remaining the same, thereby living eternally.
4) Flight – A method of flying through the sky on divine clouds. Two types are offered: “cloud-soaring” (jiayun, 駕雲), the most common method used by celestials throughout the cosmos. It involves stamping the foot to summon clouds (Wu & Yu, 2012, vol. 1, p. 123); and “cloud-somersaulting” (jindou yun, 筋斗雲), the method chosen by Sun (fig. 8). It involves simultaneously “mak[ing] the magic sign, recit[ing] the spell, clench[ing] the fist tightly, shak[ing] the body” and then jumping into the sky, leaping from cloud to cloud (Wu & Yu, 2012, vol. 1, p. 123). The latter method is by far the fastest, enabling the user to travel 108,000 li (33,554 mi / 54,000 km) in a single instant.
Shao (2006) states that the latter skill is based on a philosophical metaphor from Huineng’s Platform Sutra. The Chan Master explains that the common trope of the Buddha’s paradise being separated from the world of man by 108,000 li is based on a combination of the “Ten Evils” (Shi’e, 十惡) and “Eight Wrongs” (Baxie, 八邪) of Buddhism (see section III here). Those who rid themselves of these spiritual flaws will achieve enlightenment and thus arrive instantly at the Buddha’s paradise (Shao, 2006, p. 718; Huineng & Cleary, 1998, pp. 26-27). Therefore, Subodhi teaches a skill that’s a metaphor for instant enlightenment, further supporting his connection to Buddhism.
As noted in section 3.3, Sun states: “I bowed to the Patriarch of Spirit Tower and Square Inch / and perfected with him the martial arts [wuyi, 武藝]” (Wu & Yu, 2012, vol 3, p. 243). 
5) Military arts – Monkey demonstrates knowledge in troop movement, weapons (swords, spears, axes, bows and arrows, staves, etc.), and unarmed boxing. His preferred method is “Short Fist” (Duan quan, 短拳), which is known for compact, short-ranged attacks. This is likely just one of many boxing styles taught by Subodhi.
Shahar (2008) explains that the martials arts of the famed Chan Buddhist Shaolin Monastery developed during the Ming-Qing transition from a synthesis of Daoist gymnastics (stretching and breathing exercises), religious rituals, and fist techniques. This new form of spiritual cultivation ushered in the era of so-called “internal martial arts“, Taiji boxing being the most famous among them. Journey to the West was published during the late-Ming when this synthesis was in full swing. Therefore, the study of martial arts in a religious institution is an accurate snapshot of one facet of 16th-century monastic life.
Although not directly stated, the following skills are likely learned while studying under the Patriarch.
6) General magic – Monkey is shown capable of calling forth gods and spirits, growing or shrinking to any size, parting fire and water, creating impassable barriers, conjuring wind storms, casting illusions, freezing people in place, making endless doubles of himself, unlocking any lock, bestowing superhuman strength, bringing the dead back to life, etc.
7) Traditional Chinese Medicine – Monkey knows how to analyze a patient’s pulse and then concoct individualized medicine from a number of raw ingredients.
This makes sense as a knowledge of harming and healing often goes hand in hand in traditional Chinese martial arts. A prime example is the folk hero Wong Fei-Hung (黃飛鴻, 1847-1925), a Hung Ga boxer and physician from Qing-era Guangdong.
The breadth of skills taught to Monkey speaks to the Patriarch’s own vast array of religious, magical, and martial abilities. But he displays (or at least hints at having) the following three powers.
Subodhi demonstrates the ability to see peoples, events, and times beyond his person in chapter one when Monkey first arrives at his home. An immortal lad opens the door and tells the primate:
“My master … has just left his couch to give a lecture on the platform. Before even announcing his theme, however, he told me to go out and open the door, saying, ‘There is someone outside who wants to practice austerities. You may go and receive him'” (Wu & Yu, 2012, vol. 1, pp. 113-114).
At the end of chapter two, Subodhi makes a statement suggesting that he is aware of all things:
I forbid you ever to mention that you are my disciple. For if you but utter half the word, I’ll know about it; you can be assured, wretched monkey, that you’ll be skinned alive (Wu & Yu, 2012, vol. 1, p. 125).
5.3. Control of spirits and karmic results
He continues: “I will break all your bones and banish your soul to the Place of Ninefold Darkness [Jiuyou zhi chu, 九幽之處], from which you will not be released even after ten thousand afflictions!” (Wu & Yu, 2012, vol. 1, p. 125). This latter ability implies that he has some control over souls and their karmic punishment in the afterlife.
5.4. Possible reason for expelling Monkey
The aforementioned powers bring up the following question: “If Subodhi has these abilities, why would he take Sun as a disciple knowing full well that he would later expel him for simply displaying his newly cultivated powers?” Someone might say showing off is a sign of ego and the need for validation, qualities unbecoming of a spiritual cultivator. But there is a better answer. Being a bodhisattva with the power of foresight, the Patriarch would no doubt foresee Monkey’s later attainment of Buddhahood, realizing that the trials and tribulations of protecting the Tang Monk on the journey to India would be the price that he needs to pay to gradually awaken (jianwu, 漸悟) his enlightenment. Therefore, expelling Sun would ignite the chain of events leading to his eventual Buddhahood. This makes Subodhi an agent of Dharma, one who uses whatever methods necessary to bring about the enlightenment of his disciples.
The Patriarch Subodhi finds his origins in Subhūti, one of the ten principle disciples of the historical Buddha known for his knowledge of “emptiness”. The literary figure’s connection to Buddhism is not in name only, however. The Chinese name used most in the novel to refer to Subodhi is Puti, a transliteration for bodhi (“awakening” or “enlightenment”). His story in Journey to the West is partly based on events from the lives of the respective Fifth and Sixth Chan (Zen) Patriarchs and their transmission of the Dharma. A poem in chapter one even compares him to the Buddha and the splendor of the Western paradise, as well as further ties him to emptiness and enlightenment.
The name of Subodhi’s home, Cave of the Slanted Moon and Three Stars on the Mountain of Spiritual Heart and Elixir Mind, serves as a double metaphor for Daoist internal alchemical practices and Buddhist concepts of the mind. It is described as a mountain paradise, and the cave therein is said to be filled with grand architecture, which is centered around the Patriarch’s green jade lecture platform. The mountain is located in the Western Godaniya Continent of Hindo-Buddhist cosmic geography, placing it squarely in India, home of the historical Subhūti.
Subodhi’s students likely wear a red robe with large, open sleeves, a yellow sash, and black boots, and they are named according to a twelve generation character list. His choice for the Monkey King’s religious name, Sun Wukong, is packed full of philosophical significance related to the formation of a Daoist immortal spirit embryo and the manifestation of enlightenment. As for the Patriarch’s curriculum, he teaches Buddho-Daoist philosophy, the secret of eternal life, transformations, flight via cloud, armed and unarmed military arts, general magic, and Traditional Chinese Medicine. Tests of spiritual intelligence appear to be used to permit only the brightest into his inner circle.
Subodhi exhibits (or hints at having) clairvoyance, omniscience, and control over souls and karmic results. His power of foresight might then explain why he accepted Monkey as a student, only to later expel him. This was likely done to ignite the chain of events that would eventually lead to Sun’s achievement of Buddhahood, thereby completing the last of Zhang Boduan’s two-step process towards Buddo-Daoist transcendence.
Journey to the West stresses the Patriarch’s status as a Buddhist deity, albeit one with Daoist leanings. Therefore, I suggest that he is a bodhisattva like (as one scholar has proposed) the historical Subhūti. A Daoist bodhisattva, however, is not a paradox as such figures appear in late-Ming syncretic popular literature. Examples include the former high-ranking immortals-turned-bodhisattvas Guanyin, Mañjuśrī, and Samantabhadra from Investiture of the Gods (c. 1620).
Above I mentioned that Puti (菩提) is used at least three times to refer to Subodhi, thus stressing the Patriarch’s connection to the Buddhist concept of bodhi (Pāli / Sk: “awakening” or “enlightenment”). There’s actually a fourth usage, appearing in the title of chapter two: “Fully awoke to Bodhi’s wondrous truths / He cuts off Mara, returns to the root, and joins Primal Spirit” (Wu che puti zhen miao li / Duan Mo gui ben he yuanshen, 悟徹菩提真妙理 / 斷魔歸本合元神) (Wu & Yu, 2012, p. 116). The title serves as a double reference to the end of Prince Siddhārtha‘s path to enlightenment. (I explain in this article that the author-compiler of the standard 1592 edition of Journey to the West likely based Monkey’s early life on the Buddha to make his spiritual journey more familiar to the reader.) As part of the Prince’s meditative journey inward to discover hidden truths, he faces off against the army of the heavenly demon Māra (Mo, 魔), the ruler of the illusionary world of Saṃsāra. But these evil forces are rendered powerless by Siddhartha’s supreme focus of mind and burgeoning grasp of reality. He shortly thereafter achieves enlightenment (a.k.a. bodhi) (Beal, 1883, pp. 156-163). Likewise, thanks to [Su]Bodhi’s guidance, Sun Wukong is able to also stop Mara and achieve immortality.
This free association between Buddhist (bodhi/Mara/returning to the root) and Daoist (primal spirit) concepts was common place in Ming-era religious literature. Darga (2008) explains:
Comparing the development of the embryo to the revelation of Buddhahood is typical of neidan texts of the Ming period. For instance, the Xingming guizhi (Principles of Balanced Cultivation of Inner Nature and Vital Force) uses Body of the Law (fashen 法身, dharmakāya) as a synonym for shengtai. The birth of the embryo represents the appearance of the original spirit (yuanshen 元神) or Buddhahood and is understood as enlightenment (p. 884).
Therefore, the Monkey King’s immortality is synonymous with the Buddha’s enlightenment. And since Subodhi is key to Sun’s spiritual achievement, and given the Patriarch’s demonstrated connection to Buddhism in the novel, I’d like to further suggest that the character is the original disciple Subhūti. After all, he still lives in India like his namesake.
Despite all of the overwhelming evidence for the Patriarch’s connection to Buddhism, someone might point out that the novel refers to him as a “Spirit Immortal” (shenxian, 神仙) (for example). The Anthology of the Transmission of the Dao from Zhongli Quan to Lü Dongbin (Zhong Lü Chuan Dao Ji, 鐘呂傳道集, c. late-Tang) explains that this is the fourth of five kinds of transcendents  who has cast off the mortal body (per the methods outlined above) to enjoy a life free from the dust of the world (Wong, 2000, p. 29; see also here). But making this distinction in the face of Ming syncretism amounts to little more than arguing semantics. As we’ve seen, this philosophy equates achieving immortality with enlightenment. And Subodhi’s description above as having “no end and no birth” (busheng bumie, 不生不滅) embodies that, for he has both the Daoist elixir and the Buddha-mind and has thus broken free of the wheel of rebirth.
Taking a page from the Daoist Bodhisattvas of Investiture of the Gods (Fengshen yanyi, 封神演義, c. 1620), perhaps Subodhi/Subhūti was an immortal recruited by the Buddha, or the Buddhist disciple trained under the former high-ranking immortals-turned-bodhisattvas Guanyin, Mañjuśrī, and Samantabhadra. Knowing different paths to divinity would make him a more affective teacher and bodhisattva.
Here is a welcoming, modern image of Subhūti (fig. 9). The top line reads “The Honored Monk Subhūti’s Understanding of Emptiness is Number One” (Xuputi zunzhe jiekong diyi, 须菩提尊者解空第一). I love the golden halo.
Subodhi is alluded to in Investiture of the Gods (c. 1620). It reproduces a poem about the sage from chapter one of Journey to the West (section 2.3). The original reads:
A Golden Immortal of Great Awareness and of great ken and purest mien,
Master Bodhi, whose wondrous appearance like the West
Had no end or birth by work of the Double Three.
His whole spirit and breath were with mercy filled.
Empty, spontaneous, it could change at will,
His Buddha-nature able to do all things.
The same age as Heaven had his majestic frame.
Fully tried and enlightened was this grand priest (Wu & Yu, 2012, vol. 1, p. 114).
Chapter 61 of Investiture of the Gods reproduces the poem with only minor changes (indicated in red):
A Golden Immortal of Great Awareness and timelessness,  Dharma Master Bodhi of the wondrous West
Had no end or birth by work of the Double Three.
His whole spirit and breath were with mercy filled.
Empty, spontaneous, it could change at will,
His Buddha-nature able to do all things.
The same age as Heaven had his majestic frame.
Fully tried and enlightened was this grand priest (emphasis mine). 
It goes on to associate the poem with a Buddhist deity known as “Person of the Way, Cundī“ (Zhunti daoren, 準提道人) (fig. 10). This figure is traditionally considered a multi-armed, female bodhisattva with a strong connection to the Cundā Dhāraṇī, a power-bestowing mantra (Buswell & Lopez, 2014, p. 204). Therefore, it appears that the author was trying to provide an origin for Subodhi (likely based on “提” (ti) appearing in both character’s names). Afterall, the novel is often considered a sequel to Journey to the West because it reveals the origins of many secondary characters (Li Jing, Nezha, Muzha, Erlang, etc.). However, it’s important to remember that Investiture of the Gods is still a separate novel by a different author. So, any events therein should NOT be considered canon for Journey to the West. Besides, the latter work clearly establishes a link between Subodhi and the historical Subhūti.
Fig. 10 – Person of the Way, Cundī (top right) fighting against a rogue immortal (lower left) (larger version). From a modern manhua comic book. Image found here.
It turns out that Subodhi is not the invention of the author-compiler  of the standard 1592 edition of Journey to the West. He appears in the earlier “Zhu edition” of the novel, a.k.a. Chronicle of Deliverances in Tang Sanzang’s Journey to the West (Tang Sanzang Xiyou shi e zhuan, 唐三藏西遊释厄傳) by Zhu Dingchen (朱鼎臣).  The following quote indicates the differences between the Zhu edition (red) with the 1592 edition (black):
With solemnity the Monkey King set his clothes in order and followed the boy into the depths of the cave. They passed rows and rows of lofty towers and huge alcoves, of pearly chambers and carved arches. After walking through innumerable quiet chambers and empty studios, they finally reached the base of the green jade platform. Patriarch Subodhi was seen seated solemnly on the platform, with thirty lesser immortals standing below in rows. He [It] was truly a realm of immortals. Let’s listen to the explanation in the next chapter. (emphasis mine)
[Poem describing Master Subodhi. See above for translation. The Zhu version has a typo in the line “Grand priest” (“大怯師” instead of “大法師”).]
The Zhu version is comprised of ten scrolls (juan, 卷) with three to ten subsections each. These subsections differ from the chapter layout of the 1592 edition. For example, subsections one to three and four to five respectively correspond to chapters one and two of the 1592 edition (Koss, 1981, pp. 14-15). It’s interesting to note that the above poem caps the first subsection of scroll one. This is why it ends with: “Let’s listen to the explanation in the next chapter” (qieting xiahua fenjie, 且聽下回分解).
Monkey’s religious name Wukong (悟空), or “Awakened to Emptiness“, predates the 1592 and Zhu editions, appearing as early as an early-Ming zaju play. Therefore, I’d like to suggest that the historical Subhūti was chosen as the basis for a master worthy of bestowing this name because of his great knowledge of emptiness, as well as the large role that he plays in the Diamond Sutra (Sk: Vajracchedikā Prajñāpāramitā Sūtra; Ch: 金剛般若波羅蜜多經, Jingang bore boluomiduo jing, a.k.a. Jingang jing, 金剛經). After all, the scripture “deals with the concept of emptiness” despite never once “employ[ing] the word for emptiness śūnyatā [Ch: kong, 空]” (Watson, 2010, p. 75).  Alluding to the sutra makes sense as it was so overwhelmingly popular when Journey to the West was written that tales of its miracles were eventually compiled during the late-Ming and Qing dynasties (Ho, 2019). So, the people reading the novel would have no doubt recognized Subodhi as an allusion to Subhūti from the scripture.
The late-13th-century version of the Journey to the West story cycle already presents Monkey as an ancient Daoist immortal with magic powers from the very beginning. Therefore, this element likely played a role in draping the Buddhist master in a thin veil of Daoism to create the Buddho-Daoist sage Subodhi.
I just learned that the uber popular cartoon Lego Monkie Kid has introduced Master Subodhi in the recent 4th season. The following clip shows him training the reincarnations of Tripitaka, Zhu Bajie, and the White Dragon Horse and apparently the original Sha Wujing (video 1).
Video 1 – Master Subodhi trains new students in Lego Monkie Kid season 4.
Above in section 2.3, I mentioned how Subodhi’s seemingly paradoxical depiction as a Daoist bodhisattva wasn’t weird as other vernacular literature of the time included such beings:
A Daoist bodhisattva may seem paradoxical, but this concept comfortably fits into the syncretic worldview espoused in late-Ming literature. For example, three well-known bodhisattvas are depicted as former high-ranking immortals in Investiture of the Gods (Fengshen yanyi, 封神演義, c. 1620). These include Guanyin (觀音) as “Person of the Way, Compassionate Ferry” (Cihang daoren, 慈航道人), Mañjuśrī (Wenshu, 文殊) as the “Dharma-Spreading Heavenly Master of Outstanding Culture” (Wenshu guangfa tianzun, 文殊廣法天尊), and Samantabhadra (Puxian, 普賢) as the “Perfected Man of Universal Virtue” (Puxian zhenren, 普賢真人). Together, they later convert to Buddhism and become disciples of the Buddha (hou xing shimen, chengyu fojiao, 後興釋門，成于佛教) at the end of chapter 83.
Well, I was happy to learn that Qingyang Temple in Chengdu, Sichuan Province, China (Chengdu Qingyang Gong, 成都青羊宮) houses idols to the three Daoist bodhisattvas from Investiture of the Gods (fig. 11 to 14).

1) The list of Xuputi variations comes from Soothill & Hodous, 1937/2014, p. 394.
2) Osto (2016) continues:
This conception that certain disciples of the Buddha were actually crypto-bodhisattvas fits in well with the Prajñāpāramitā idea … that a true bodhisattva does not maintain the idea that ‘I am a bodhisattva‘. Though these bodhisattva-disciples are actually bodhisattvas in guise of disciples, as true bodhisattvas, they would never admit to being bodhisattvas, because the false conception of ‘bodhisattva‘ as a truly existent dharma with ‘own-being’ never occurs in their minds (p. 128).
3) The English translation glosses over this, choosing instead to state how the three “not long thereafter” became the aforementioned bodhisattvas (Gu, 2000, p. 1737).
4) Source slightly altered. I’ve made the translation more accurate. I will do this with the rest of Yu’s (Wu & Yu, 2012) translation where necessary.
5) Yu (Wu & Yu, 2012) suggests that this poem is related to the Buddha’s statement that Sun is “only a monkey who happened to become a spirit, … merely a beast who has just attained human form in this incarnation” (p. 70). This alludes to a Confucian hierarchical scale present in the novel where animals are able to attain human qualities through spiritual cultivation. So Monkey’s training under Subodhi allows him to wed his monkey form to the human heart-mind.
8) An example of the Monkey King’s knowledge of Buddhist scripture happens in chapter 93:
“Disciple,” said the Tang Monk, “it may be true that the land of Buddha is not far away. But remember what the temple priests told us the other day: the distance to the capital of the Kingdom of lndia is still some two thousand miles. I wonder how far have we gone already.”
“Master,” said Pilgrim, “could it be that you have quite forgotten again the Heart Sūtra [Xinjing, 心經] of the Crow’s Nest Chan Master?”
Tripitaka said, “That Prajñā-pāramitā is like a cassock or an alms bowl that accompanies my very body. Since it was taught me by that Crow’s Nest Chan Master, has there been a day that I didn’t recite it? Indeed, has there been a single hour that I didn’t have it in mind? I could recite the piece backward! How could I have forgotten it?”
“Master, you may be able to recite it,” said Pilgrim, “but you haven’t begged that Chan Master for its proper interpretation.”
“Ape-head!” snapped Tripitaka. “How dare you say that I don’t know its interpretation! Do you?”
“Yes, I know its interpretation!” replied Pilgrim. After that exchange, neither Tripitaka nor Pilgrim uttered another word. At their sides, Eight Rules nearly collapsed with giggles and Sha Monk almost broke up with amusement.
“What brassiness!” said Eight Rules. “Like me, he began his career as a monster-spirit. He wasn’t an acolyte who had heard lectures on the sūtras, nor was he a seminarian who had seen the law expounded. It’s sheer flimflam and pettifoggery to say that he knows how to interpret the sutra! Hey, why is he silent now? Let’s hear the lecture! Please give us the interpretation!”
“Second Elder Brother,” said Sha Monk, “do you believe him? Big Brother is giving us a nice tall tale, just to egg Master on his journey. He may know how to play with a rod. He doesn’t know anything about explaining a sūtra!”
“Wuneng and Wujing,” said Tripitaka, “stop this claptrap! Wukong’s interpretation is made in a speechless language. That’s true interpretation” (Wu & Yu, 2012, vol. 4, pp. 264-265)
9) These methods are named after a set of 108 stellar deities from Chinese astrology and popular literature. Sources describe the 72 stars as malevolent, while the 36 are more helpful. I follow the translation of these names from Meulenbeld (2019).
10) Thanks again to Irwen Wong for bringing these examples to my attention.
11) The term wuyi has been used as far back as the third-century CE to refer to Chinese martial arts. It predates the more familiar wushu (武術) by some three centuries (Lorge, 2012, p. 10).
The three paths of cultivation are the Lesser Path, the Middle Path, and the Great Path. The five classes of immortals are ghost immortal, human immortal, earth immortal, spirit immortal, and celestial immortal (Wong, 2000, p. 29).
13) The original Chinese characters that I chose to translate as “timelessness” are “不二時” (bu ershi). Soothill and Hodous (1937/2014) define the phrase “二時” (ershi) as: “The two times or periods—morning and evening. Also 迦羅 kāla, a regular or fixed hour for meals, and 三昧那 samaya, irregular or unfixed hours or times” (p. 25). They further define kāla as: “a definite time, a division of time; the time of work, study, etc., as opposed to leisure time” (Soothill and Hodous, 1937/2014,p. 316). Therefore, the Investiture of the Gods poem might be suggesting that the intended character is beyond time.
14) The English version doesn’t even translate the poem (Gu, 2000, pp. 1248 and 1249).
15) The question of Wu Cheng’en‘s authorship is beyond the scope of this article.
16) Koss (1981) performs an in-depth analysis of the standard 1592, Zhu, and Yang editions of the Ming-era Journey to the West, showing that the 1592 edition is an expansion of Zhu and Yang is a later abridgement of the former. Zhu being the oldest, with portions likely predating 1450, is based on its earlier style phrasing and chapter structure; the use of vernacular language with simplistic two-person dialogue and fewer and less literary poems, suggesting a reliance on oral literature; and Zhu illustrations serving as the basis for many pictures from the 1592 edition.
17) The Diamond Sutra uses an “A is not-A” structure to negate anything and everything that might lead to physical or spiritual clinging. For example, one passage reads:
“Subhūti, [if a bodhisattva] were to say, ‘I am going to save a countless number of living beings,’ then one could not call that person a bodhisattva. Why? Because, Subhūti, there is no such dharma called a bodhisattva. Therefore, the Buddha teaches that, with regard to all dharmas, there is no self, no being, no living creature, no individual.”
“Subhūti, if a bodhisattva were to say, ‘I will adorn the buddha lands,’ he cannot be called a bodhisattva. Why? Because the Buddha teaches that to adorn the buddha lands is not to adorn them. This is called adorning. Subhūti, if the bodhisattvas thoroughly understand that there is no such thing as a self, then the [Tathāgata] declares that they are truly worthy to be called bodhisattvas” (Watson, 2010, p. 90).
“Adorning the Buddha land” refers to the treasure-like splendor of the heavenly paradises created for those saved by bodhisattvas (Watson, 2010, p. 83 n. 20).

From time to time I like to post a fun blog not directly related to (though informed by) my research. A past example can be seen here. Regular articles will resume after this entry.

Sun Wukong is kicked out of Patriarch Subodhi‘s (Xuputi zushi, 須菩提祖師) school in chapter two of Journey to the West (Xiyouji, 西遊記, 1592) for showing off his transformation skills to his less-accomplished religious brothers. Upon their request, he changes into a perfect pine tree that’s completely indistinguishable from a real one. The subsequent applause greatly disturbs the Master, who reprimands and expels the Monkey King under the pretense of saving his life from those who would harm him to learn his heavenly secrets (Wu & Yu, 2012, vol. 1, pp. 123-125). 
The novel briefly mentions that Sun Wukong lives for ten years in the mountain home of the Buddho-Daoist sage Master Subodhi. The first seven are spent as a junior Daoist monk doing menial tasks and learning basic religious or life skills. However, the last three years are spent as a close disciple of Subodhi, learning elixir arts, magic, and combat skills. The novel glosses over his early cultivation in order to jump directly into the action. But imagine a Xianxia story focusing on those three years.
Drama with fellow disciples could arise from Monkey’s supernatural aptitude for quickly learning and mastering a skill. After all, it only takes him three years to go from a mere stone monkey to a powerful immortal capable of going toe-to-toe with gods and demons with millennia of cultivation and combat experience. Think of the resulting battles between our hero and his jealous senior religious brothers and sisters frustrated with his great progress.
In addition, given Sun’s demonstrated knowledge in boxing, weapons, and troop movement, I came up with the story idea that Subodhi’s school is the training ground for an immortal monastic army akin to the famous Shaolin temple. Shaolin was mobilized by the Chinese government during the 16th-century to battle pirates attacking the coast. Records indicate that one historical Shaolin monk was made the leader, and he was later forced to singlehandedly defend himself against eight individuals vying for his position. Likewise, I imagine heaven calls up Subodhi’s army to battle some demonic evil, and Monkey might quickly rise through the ranks. This would naturally lead to more tension with his fellow disciples, causing him to defend his position. All of these challenges, plus any action seen by the monastic army in heavenly battles, would explain how Sun Wukong became such a seasoned fighter in such a short time.
Plus, there is the added bonus of Subodhi’s army being called upon to fight Sun during his rebellion against heaven. He might have far surpassed his religious brothers and sisters in skill at this point.
In chapter one, Subodhi is shown to have 12 generation names (zibei, 字輩) used to name the students of his religious lineage, three of which were historically used by Daoism. 
Jue (覺) (Wu & Yu, 2012, p. 115).
Monkey is part of the tenth generation (Wu & Yu, 2012, p. 115). This means that all of Subodhi’s students taken in around the same time would all have Wu (悟) in their name. Perhaps Sun trains with his fellow Wu cohort but quickly moves on to older generations as his skill rapidly progresses.
This leads me to my next point. Above, I mentioned that Subodhi’s army might be called to bear against Monkey during his rebellion. But wouldn’t they recognize him? This feeds into a common question asked around the internet:
Why doesn’t Wukong run into any fellow disciples on the journey?
Well, the simple answer is that this isn’t important to the plot. But I’ve considered two ideas to work around this: One, his younger religious brothers are likely still studying under the Master. And two, the older generations—the ones serving in the monastic army—probably don’t know what Monkey looks like because advanced disciples, within the present story, are made to wear a host of fierce, multi-colored masks (fig. 1) as a way to forsake their identity and subsume the self into deep spiritual and martial cultivation. They would represent the negative thoughts and emotions that keep humans trapped in the illusionary world of Saṃsāra and chained to the wheel of rebirth. Perhaps the face becomes more human and peaceful-looking as the students progress through their training.
Also, in my version of the story universe, all immortals and deities attain a halo upon achieving divine status. Here, for example, is a photomanipulation of a haloed Sun Wukong by Elijah McTaggart and myself. Take note of the fiery aureola engulfing the halo. This will come into play shortly (fig. 2). I imagine that these halos/aureolas respectively spin and shine brighter when a divinity’s spiritual power is used.
The reason I’ve devised is connected to one of the aforementioned fights between Monkey and his older religious brothers or sisters. Perhaps Sun is attacked by multiple powerful assailants at once (just like the historical Shaolin monk), and when they start to overwhelm him, his anger ignites his halo, which begins to furiously spin and produce a radiant splendor. Instantly, he takes on a titanic cosmic form, growing 100,000 feet (30,480 m) tall and stomping on his assailants. At the same time, his docile-looking mask cracks and reverts to it’s original, fierce form. This, combined with a fiery aureola, gives him the appearance of a giant Dharmapala (Ch: Fahu, 法護), a wrathful “Protector of the Dharma” (Buddhist Law) (fig. 3) (Buswell & Lopez, 2014, pp. 249-250). This display of raw, untamed spiritual power frightens his older religious brethren. Subodhi himself is also taken aback as Monkey exhibits a great, fiery anger, while also manifesting advanced cultivation techniques that haven’t even been taught to him yet—a testament to his great spiritual intelligence. The Master fears that this rage, combined with Monkey’s demonstrated talent for exponential spiritual growth and perhaps a problem with controlling this power (given Sun’s short years of study), will lead him down the path to villainy.
This brings us back to the pine tree incident. Perhaps the fight causes Subodhi to uncharacteristically allow Monkey a chance to visit his generational cohort. And when Sun acquiesces to their requests to see his transformation powers, the Master uses this as an opportunity to expel his student.
As before, each would indicate the level of a disciple’s spiritual attainment. Perhaps Master Subodhi’s army would have different units of each category, each one being more powerful than the last.
Some readers might question why I’ve included so many Buddhist elements if Master Subodhi is a Daoist immortal. While this is true, I choose instead to refer to him as a “Buddho-Daoist Sage” as he preaches aspects of both religions in his lectures:
With words so florid and eloquent That gold lotus sprang from the ground. The doctrine of three vehicles he subtly rehearsed, Including even the laws’ minutest tittle. The yak-tail waved slowly and spouted elegance: His thunderous voice moved e’en the Ninth Heaven. For a while he lectured on Dao; For a while he spoke on Chan– To harmonize the Three Parties is a natural thing. One word’s elucidation filled with truth Points to the birthless showing nature’s mystery (Wu & Yu, 2012, p. 122) (emphasis mine).
He even advocates for his students to become Buddhas. For example, the poem that Subodhi uses to reveal the secret of immortality to Monkey ends with: “When that’s done, be a Buddha or immortal at will!” (Wu & Yu, 2012, p. 120).
It’s also important to remember that Master Subodhi is based on Subhuti, a historical disciple of the Buddha.
1) I quote the scene of his expulsion below:
“You, Wukong, come over here! I ask you what sort of exhibition were you putting on, changing into a pine tree? This ability you now possess, is it just for showing off to people? Suppose you saw someone with this ability. Wouldn’t you ask him at once how he acquired it? So when others see that you are in possession of it, they’ll come begging. If you’re afraid to refuse them, you will give away the secret; if you don’t, they may hurt you. You are actually placing your life in grave jeopardy.” “I beseech the master to forgive me,” Wukong said, kowtowing. “I won’t condemn you,” said the Patriarch, “but you must leave this place.” When Wukong heard this, tears fell from his eyes. “Where am I to go, Teacher?” he asked. “From wherever you came,” the Patriarch said, “you should go back there.” “I came from the East Purvavideha Continent,” Wukong said, his memory jolted by the Patriarch, “from the Water-Curtain Cave of the Flower-Fruit Mountain in the Aolai Country.” “Go back there quickly and save your life,” the Patriarch said. “You cannot possibly remain here!” “Allow me to inform my esteemed teacher,” said Wukong, properly penitent, “I have been away from home for twenty years, and I certainly long to see my subjects and followers of bygone days again. But I keep thinking that my master’s profound kindness to me has not yet been repaid. I, therefore, dare not leave.” “There’s nothing to be repaid,” said the Patriarch. “See that you don’t get into trouble and involve me: that’s all I ask.” Seeing that there was no other alternative, Wukong had to bow to the Patriarch and take leave of the congregation. “Once you leave,” the Patriarch said, “you’re bound to end up evildoing. I don’t care what kind of villainy and violence you engage in, but I forbid you ever to mention that you are my disciple. For if you but utter half the word, I’ll know about it; you can be assured, wretched monkey, that you’ll be skinned alive. I will break all your bones and banish your soul to the Place of Ninefold Darkness [Jiuyou zhi chu, 九幽之處], from which you will not be released even after ten thousand afflictions!” “I will never dare mention my master,” said Wukong. “I’ll say that I’ve learned this all by myself.” Having thanked the Patriarch, Wukong turned away, made the magic sign, pulled himself up, and performed the cloud-somersault (Wu & Yu, 2012, pp. 124-125).
