Story Idea: The REAL Reason Sun Wukong is Expelled from Subodhi’s School

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.

Last Updated: 08-27-2022

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). [1]

This event is a turning point in Sun’s life, for he transitions from an inward pursuit of spiritual cultivation to an external quest for power, ending with an attempt to unseat the Jade Emperor (Yuhuang shangdi, 玉皇上帝). This ultimately leads to the Buddha imprisoning the seditious primate beneath Five Elements Mountain and punishing him to a hellish diet for 600 plus years.

Here, I would like to prepose a different reason, one that makes more sense and better aligns with some of my previous story ideas.

I. The story so far

Last year I posted a story prompt to reddit to inspire writers looking for a Xianxia (仙俠, “immortal hero”) plot. It serves as a good summation of my past ideas:

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.

II. Additions

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. [2]

  1. Guang (廣)
  2. Da (大)
  3. Zhi (智)
  4. Hui (慧)
  5. Zhen (真)
  6. Ru (如)
  7. Xing (性)
  8. Hai (海)
  9. Ying (穎)
  10. Wu (悟)
  11. Yuan (圓)
  12. 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.

III. Why he is really kicked out

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.

IV. My thoughts

I like this idea because it foreshadows Sun’s cosmic transformations throughout the novel (ch. 3, 6, 61, and 97). It also foreshadows his later mischief throughout the cosmos and eventual rebellion. 


Update: 05-16-22

I imagine Master Subodhi’s mask-wearing monastic army would have an ominous feel to them just like the stylized Persian “immortals” from the film 300 (2006) (fig. 4).

Update: 05-20-22

On second thought, a better mask would emulate the six paths of reincarnation in Buddhist cosmology:

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.


Update: 05-24-22

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.


Update: 08-27-23

Above, I suggested that Subodhi’s advanced students could wear masks similar to the Tibetan Cham dancers. Well, someone on Facebook posted lovely images of said dancers by the photographer “JKBoy” Jatenipat Ketpradit (fig. 5-7). I just wanted to share some of them so that readers will have a better understanding of what the students might look like.

Notes:

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).

How Tall is the Monkey King? – A Debate

This was originally posted as a 03-03-2022 update to an existing article, but I decided to make it a standalone piece.

Last updated: 04-27-2024

In “What Does Sun Wukong Look Like?” I highlighted several sentences pointing to the Monkey King’s small stature (fig. 1 & 2). For example, one monster comments:

The old monster took a careful look and saw the diminutive figure of Pilgrim [Monkey]—less than four Chinese feet [buman sichi, 不滿四尺, 4.17 ft or 1.27 m] in fact—and his sallow cheeks. He said with a laugh: “Too bad! Too bad! I thought you were some kind of invincible hero. But you are only a sickly ghost, with nothing more than your skeleton left!” (Wu & Yu, 2012, vol. 1, p. 408).

This information was later used in the making of a youtube video called “10 Facts About Sun Wukong the Monkey King.” Fact number seven was that “He’s really short,” and I ended the section by saying: “That’s right! The Great Sage Equaling Heaven, the conqueror of the heavenly army … is the size of a child.” A Chinese viewer later left a thought-provoking comment on the video stating that I was wrong about Monkey’s size.

The Debate

Here, I will present the comment in full but interspersed with my responses:

Hello! I am a Wukong fan from China. I really enjoyed your video! I would like to say that the height of the Monkey King has been very controversial on the internet in China. The data and appearance depictions in classical Chinese novels can be somewhat exaggerated. Journey to the West is a mythological novel is even more so. For example, seventy-two transformations, a somersault that can travel one hundred thousand eight hundred thousand li respectively refer to infinite changes and fly extremely fast. Seventy-two and one hundred and eighty thousand are not exact numbers, so relying solely on data is not reliable. Besides, in addition to four feet, Wukong has also appeared other height data. For example, the earliest version of the Journey to the West, “世德堂本”, Chapter 21. “大圣公然不惧。那怪果打一下来,他把腰躬一躬,足长了三尺,有一丈长短。” “Our Great Sage was not in the least frightened. When the monster struck him once, he stretched his waist and at once grew three chi, attaining the height of one zhang altogether.”

This PDF scan (page 258) shows the original version of the novel did indeed read “grow three chi” (changle sanchi, 長了三尺) and not six like in the modern version (Wu & Yu, vol. 1, p. 408). I was surprised when this was brought to my attention.

One zhang minus three chi equals seven chi. In other words, the height of the Monkey King here was seven chi (Since the height unit in Chinese classical novels is based on the ancient system, 7 chi is around 5.5 feet). But in later versions and translations, “grew three chi” was changed to six chi. This has always been a point of contention. The figure of four feet (four chi) appears twice, both from the perspective of other monsters, such as the Monstrous King, who is three zhangs tall (around 24 feet). It may be possible that Sun Wukong is short in his eyes in comparison.

For those unfamiliar with ancient Chinese measurements, one zhang () equals ten chi (尺, i.e. “Chinese feet”) (Jiang, 2005, p. xxxi). The passage in question does imply that Monkey is seven chi tall. However, there are two problems. First, during the Ming (1368-1644) when the novel was published, one chi equaled approximately 12.52 inches (31.8 cm) (Jiang, 2005, p. xxxi). This would make Sun a whopping 7.3 feet (2.22 m) tall! I must admit that the chi varied at the local level, but I doubt the variations would lead to a nearly two-foot (60.96 cm) difference. Additionally, if we use the measures for the Tang (618-907 CE), when the story is set, a chi was 11.57 inches (29.4 cm), making Monkey 6.75 feet (2.06 m) tall. There was, however, a “small chi” (xiaochi, 小尺) at this time, which was 9.66 inches (24.6 cm) (Nienhauser, 2016, p. 405 n. 40). This would only make him 5.65 feet (1.72 m) tall. But I would question if the common folk reading the novel during the Ming were aware of and still using this truncated measure. Second, as written above, the figure for “not even four chi” (buman sichi, 不滿四尺, 4.17 ft or 1.27 m) appears twice. But it’s important to note that this estimate is made by two different characters at two different locations and times. The first is spoken in chapter two by the Monstrous King of Havoc (Hunshi mowang, 混世魔王) in the Water Belly Cave (Shuizang dong, 水臟洞) of the Mountain of Flowers and Fruit (east of the Eastern Purvavideha Continent) (PDF page 36; Wu & Yu, 2012, vol. 1, p. 128). This takes place over 100 years before Sun’s initial rebellion during the Han Dynasty (202 BCE-220 CE). And the second is spoken in chapter 21  by Great King Yellow Wind (Huangfeng dawang, 黃風大王) in the Yellow Wind Cave (Huangfeng dong, 黃風洞) of Yellow Wind Ridge (Huangfeng ling, 黃風嶺) somewhere in the Southern Jambudvipa Continent (PDF page 258; Wu & Yu, 2012, vol. 1, p. 408). This takes place sometime after his release from his 600-plus-year punishment under Five Elements Mountain during the Tang Dynasty (618-907 CE). Therefore, this seems like a more reliable measure—given the distance between themthan the ten minus three argument. I suggest the latter was actually a typo that later editions tried to amend by changing three to six. 

Another reason is that the author may be deliberately blurring the height of the Monkey King. Because at least in the story, the author describes Wukong according to the height of normal people. For example: Before Wukong learned Magic skills, when he could not change his height, he had robbed ordinary people’s clothes to wear. If Wukong was the height of a child, the clothes would hardly fit. When Wukong set out on his journey to the west, he once wore the clothes of Tang Monk. Wukong could carry the Taoist priest changed by the Silver Horned King (if he was a child height this would be very difficult).

These are good points, but a 7.3-foot tall Monkey wouldn’t be able to wear the clothing of the aforementioned people either. Conversely, tucking in or rolling up clothing wouldn’t be out of the question. And carrying a priest wouldn’t be a problem for a small-statured hero capable of hoisting the weight of two cosmic mountains while running at meteoric speeds.

In the same chapter, the Tang monk sitting on the horse can pull Wukong’s tiger skin skirt. Wukong can easily grab Eight Rules’ ear. In the Bhikṣu Kingdom, Wukong once exchanged clothes with Tang monk, etc.

Horses are tall animals, so the Tang Monk would’ve probably fallen off before even grabbing the skirt of an adult-sized Sun Wukong. I look at this as something that sounds good on paper until it’s tried in real life.

I think even a 5.5-foot tall Monkey would have problems grabbing the ear of Zhu Bajie, who is likely 10 feet (3.05 m) tall or more given his three chi (3.13 ft / 95.4 cm) snout (PDF page 108; Wu & Yu 2012, vol. 4, p. 149) and giant body that “causes even the wind to rise when he walks” (PDF page 367; Wu & Yu 2012, vol. 2, p. 51). Either way, jumping would be involved, making this irrelevant.

And just because Sun might be smaller doesn’t mean he wears child-sized clothing. I believe the first instance of sharing clothes happens in chapter 14: “Pilgrim … noticed that Tripitaka had taken off a [robe] made of white cloth and had not put it on again after his bath. Pilgrim grabbed it and put it on himself” (PDF page 174; Wu & Yu, vol. 1, p. 313). He seems to wear whatever is available to him.

In China, there is another speculation about Wukong’s height: monkeys are usually hunched over. Wukong is four chi tall when bent over and seven chi tall when standing upright.

I studied primates in college. Monkeys usually walk on their palms (palmigrade) (fig. 3) and only stand when foraging, fighting, or carrying things. But I don’t recall the novel ever mentioning Sun traveling on all fours (please correct me if I’m wrong). Therefore, he likely walks on two legs. In this case, as stated, monkeys have a hunched posture when standing. They can’t stand straight because of mechanical limitations in their skull, spine, hips, legs, and feet (my previous essay on hominids applies to monkeys as well). One could argue that Monkey can overcome these limitations with his immortal body, but this definitely wouldn’t give him three more chi of height. For example, here’s a macaque standing at full height (fig. 4). As can be seen, straightening the head, spine, and legs would only give a handful of inches or centimeters.

Fig. 3 – A macaque skeleton in its natural posture (larger version). Fig. 4 – A young macaque male standing (larger version).

And as stated in this article, Sun shares all of the hallmarks of a macaque, including a “furry, joweless face with fiery eyes, a broken or flat nose, a beak-like mouth with protruding fangs, and forked ears.” This likely includes a smaller stature.

Of course, there is no doubt that he is very thin, and is definitely the shortest one in the scripture takers, but at least, his height is more like that of a shorter adult than a child. The role of Sun Wukong is a combination of human nature, monkey nature, and divinity. The author may be deliberately obscuring his height. Therefore, when describing daily life, Wukong is the same height as normal people, but in the eyes of other demons, he is more prominent in the shape of the monkey. And he has the divine power to change his height at will. Sorry for my bad English, really enjoyed your video!

I will concede that four chi is a rough estimate, so he might be slightly shorter or even taller than this. Either way, he’d be far below average human height.


Update: 03-06-22

Chapter 20 includes a scene where Monkey refers to his stature: “A person like me, old Monkey, may be small but tough, like the skin around a ball of ligaments!” (PDF page 246; Wu & Yu, 2012, vol. 1, p. 395).


Update: 03-08-22

Above, I suggested that the ten minus three argument was a typo. But there might be a numerological explanation. Qing-era scholar Wang Xiangxu (汪象旭, fl.1605-1668) borrowed from the Daoist philosophy of Zhang Boduan (張伯端, 987?-1082) by applying his “three fives equal one” (sanwuyi, 三五一) five elements concept (fig. 5) to numbers appearing in the novel. As Shao (1997) explains:

One set of five consists of wood (3) and fire (2). Wood in the east produces fire in the south. The second set is that of metal (4) and water (1). Metal in the west produces water in the north. The third is earth in the center whose number is five. The whole business of the “gold elixir” is to integrate all three sets of five to produce one—the gold elixir (pp. 16-17).

Shao (1997) goes on to explain the numeric significance of the dharma vessel constructed from Sha Wujing’s 9-skull necklace and the heavenly gourd in chapter 22: 

Wang Xiangxu shows a keen eye for the “one” gourd and “nine” skulls which make a perfect “ten”—the number for the completion of earth. However, it is not the numbers that attract him, but what they indicate—that the gold elixir is creation—a process that involves the integration of all the five elements—not unlike the creation of the universe (p. 18).

Therefore, three (wood) and seven (fire) may be a reference to the completion of ten (the golden elixir) in Daoist numerology. If this is true, even the later switch from three to six still matches this (refer to fig. 5).

Update: 04-27-24

Chapter 37 gives a more precise measurement for Monkey’s height. He first transforms into a “tiny monk about two cun tall” (二寸長的小和尚兒) (based on Wu & Yu, 2012, vol. 2, p. 172). He shortly thereafter grows even bigger when a prince makes fun of him:

Tripitaka pulled open the box’s cover; Pilgrim [Sun Wukong] leaped out and began to hobble all over the place. The prince said, “This little midget! What can he know?” When Pilgrim heard this remark about his size, he at once resorted to magic. Straightening up his torso, he grew about three chi and four or five cun instantly (emphasis added). “If he can grow that rapidly,” said the soldiers, highly startled, “it will only be a few days before he pierces the sky.” When Pilgrim reached his normal height, however, he stopped growing (emphasis added) (based on Wu & Yu, 2012, vol. 2, pp. 174-175).

三藏扯開匣蓋兒,那行者跳將出來,呀的兩邊亂走。太子道:「這星星小人兒,能知甚事?」行者聞言嫌小,卻就使個神通,把腰伸一伸,就長了有三尺四五寸。眾軍士吃驚道:「若是這般快長,不消幾日,就撐破天也。」行者長到原身,就不長了。

As mentioned above, one chi (尺) is roughly 12.3 in or 31.8 cm (Jiang, 2005, p. xxxi). Expanding on this, one chi equals 10 cun (寸; a.k.a. “Chinese inches”) (Jiang, 2005, p. xxxi). One cun would be about 1.25 in or 3.18 cm. Two cun would therefore be 2.5 in or 6.36 cm. Growing the stated additional height would then put our hero at chi and 6 or 7 cun, which is roughly 3.86 ft or 1.176 m. This agrees with the aforementioned estimate of “not (or less than) four chi tall” (buman sichi不滿四尺) (Wu & Yu, 2012, vol. 1, pp. 128 and 408).

It’s important to note that the cited quote above does indeed appear in the original 1592 edition (see PDF page 480) (fig. 6). This proves that the aforementioned “grow three chi” (changle sanchi, 長了三尺) from PDF page 258 was a typo!
