Archive #36 – Sun Wukong and Battles of Magical Transformations

Last updated: 04-10-2022

One of the most famous episodes from Journey to the West (Xiyouji, 西遊記, 1592) happens in chapter six when heaven sends Erlang to confront Sun Wukong during his rebellion. After a prolonged, indecisive battle between the two immortals in their respective humanoid and cosmic giant forms, Monkey loses heart when his children are captured, causing him to flee. He tries to hide in the guise of a sparrow but is soon spotted by Erlang. This leads to an epic battle of magical transformations (video 1):

[…] Erlang at once discovered that the Great Sage had changed into a small sparrow perched on a tree. He changed out of his magic form and took off his pellet bow. With a shake of his body, he changed into a sparrow hawk with outstretched wings, ready to attack its prey. When the Great Sage saw this, he darted up with a flutter of his wings; changing himself into a cormorant, he headed straight for the open sky. When Erlang saw this, he quickly shook his feathers and changed into a huge ocean crane, which could penetrate the clouds to strike with its bill. The Great Sage therefore lowered his direction, changed into a small fish, and dove into a stream with a splash. Erlang rushed to the edge of the water but could see no trace of him. He thought to himself, “This simian must have gone into the water and changed himself into a fish, a shrimp, or the like. I’ll change again to catch him.” He duly changed into a fish hawk and skimmed downstream over the waves. After a while, the fish into which the Great Sage had changed was swimming along with the current. Suddenly he saw a bird that looked like a green kite though its feathers were not entirely green, like an egret though it had small feathers, and like an old crane though its feet were not red. “That must be the transformed Erlang waiting for me,” he thought to himself. He swiftly turned around and swam away after releasing a few bubbles. When Erlang saw this, he said, “The fish that released the bubbles looks like a carp though its tail is not red, like a perch though there are no patterns on its scales, like a snake fish though there are no stars on its head, like a bream though its gills have no bristles. Why does it move away the moment it sees me? It must be the transformed monkey himself!” He swooped toward the fish and snapped at it with his beak. The Great Sage shot out of the water and changed at once into a water snake; he swam toward shore and wriggled into the grass along the bank. When Erlang saw that he had snapped in vain and that a snake had darted away in the water with a splash, he knew that the Great Sage had changed again. Turning around quickly, he changed into a scarlet-topped gray crane, which extended its heel like sharp iron pincers to devour the snake. With a bounce, the snake changed again into a spotted bustard standing by itself rather stupidly amid the water pepper along the bank. When Erlang saw that the monkey had changed into such a vulgar creature-for the spotted bustard is the basest and most promiscuous of birds, mating indiscriminately with phoenixes, hawks, or crows-he refused to approach him. Changing back into his true form, he went and stretched his bow to the fullest. With one pellet he sent the bird hurtling […] (Wu & Yu, 2012, vol. 1, pp. 182-183).

Video 1 – A light-hearted, animated version of the battle between Erlang and Sun Wukong. From the 1960s classic Havoc in Heaven.

My friend Irwen Wong over at the Journey to the West Library blog has analyzed this fight, showing that Erlang’s changes are always a stronger response to the Monkey King’s transformations.

[…] 1.3. Round 3

Type: Transformation
Monkey turns himself into a sparrow and flees by flying away. Erlang notices this transformation and turns himself into a sparrow hawk to attack.
Result: Erlang wins.

1.4. Round 4

Type: Transformation
When Monkey now changes into a cormorant to be able to fly higher, out of Erlang’s hawk’s reach. Erlang was aware of this and transforms into an ocean crane to give chase.
Result: Erlang wins.

1.5. Round 5

Type: Transformation & intellect
Monkey was afraid of Erlang’s powerful transformations and turns himself into a small fish to hide in a stream. Erlang changes into a fish hawk and scans the stream for Monkey’s trace. He cleverly identifies the fish that was Monkey and attempts to catch it.
Result: Erlang wins.

1.6. Round 6

Type: Transformation
Monkey immediately darts out of the water when he sees Erlang and changes into a water snake. Erlang transforms into a grey crane to catch the water snake.
Result: Erlang wins.

1.7. Round 7

Type: Transformation & intellect
Monkey sees that Erlang had turned into a crane to chase him, so he wittily transformed into a spotted bustard to oppose Erlang’s crane.
Result: Monkey wins – Erlang as a crane did not dare approach the bustard.

1.8. Round 8

Type: Transformation & combat
When Monkey changed into a bustard, Erlang was afraid to approach it. Instead, Erlang reverted to his original form and took out his pellet bow. With the bow, he aimed at Monkey’s bustard and succeeded with a strong direct hit.
Result: Erlang wins.
[…]

This magical battle is actually related to an ancient mythic motif involving two warring supernatural beings.

I. Antecedents of the motif

Ioannis M. Konstantakos’ (2016) paper “The Magical Transformation Contest in the Ancient Storytelling Tradition” explains that the motif can be traced to the Near East of the late-3rd millennium BCE. However, the oldest variants instead depict the combatants transforming objects and not their physical bodies in battle. But the outcome is still the same: one competitor produces stronger responses to the other’s initial attack. For example, the Sumerian tale Enmerkar and Ensuhgirana (c. early-2nd millennium BCE) depicts the two titular characters engaged in a magical battle over the fate of their respective homelands. Konstantakos (2016) writes:

The competition of Sağburu and Urğirnuna consists precisely in the magical fabrication of various animals. Each one of the adversaries throws a certain object of witchcraft into the river and draws out a magically produced creature (or group of creatures). Every time, however, Sağburu’s creations are bigger, stronger, and wilder than those of Urğirnuna, which they seize and lacerate as a result. Specifically, the foreign sorcerer produces in sequence: 1) a big carp; 2) a ewe with its lamb; 3) a cow with its calf; 4) an ibex and a wild sheep; and 5) a young gazelle. The wise witch, on the other hand, counters these creations correspondingly with 1) an eagle; 2) a wolf; 3) a lion; 4) a mountain leopard; and 5) a tiger and another kind of lion. In this way, all of Urğirnuna’s creatures are eliminated, and Sağburu wins the contest (p. 210).

This finds parallels with ancient Egyptian stories and even an event from the book of Exodus (7.8-12) (Konstantakos, 2016, pp. 210-213).

The more familiar version of the motif, which sees competitors transforming their bodies, is found in ancient Greek drama. Konstantakos (2016) describes one such tale involving the lustful adventures of Zeus:

The Cypria offers the most expanded and detailed form of the saga. Zeus was amorously chasing [his daughter] Nemesis, but she was averse to his sexual intentions and ran away. In the course of her flight, Nemesis took the form of various beasts; she became a fish in the sea and swam through the Ocean’s stream; then she changed herself into many kinds of animals on the land, in order to escape. In the end, the goddess was transformed into a bird, the species of which is variously given in the ancient sources. … Zeus assimilated himself to the same species of bird, becoming respectively a gander in the former version and a male swan in the latter one. In this form, the great god finally managed to mate with the metamorphosed and bird-like Nemesis (pp. 213-214).

The body transforming motif came to influence later European stories, many involving a battle between a magician and his arrogant pupil (folklore index no. 325) (Konstantakos, 2016, p. 208).

The Greek version is very similar to the battle between Erlang and Sun Wukong, for both feature a character fleeing under different magical disguises while being chased by an assailant who undergoes stronger transformations in response. Given the link between Greek and Indian philosophy, I’d wager that there’s some ancient South Asian version of this motif that came to influence Journey to the West. I’m just happy that Monkey wasn’t handled like Nemesis in the final product. That would have been awkward for everyone!

II. Archive

Below, I archive Konstantakos (2016). The first half of the paper is fascinating, while the second is quite repetitive. It takes up a great deal of space analyzing a Near Eastern-influenced version of the motif in the Greek Alexander Romance. Please keep this in mind.

Update: 04-10-22

I’ve mentioned in this article (section 3) that the Bull Demon King‘s story arc shares many similarities with Sun Wukong’s. He too has a battle of transformations, but instead of Erlang, his opponent is the Monkey King. Chapter 61 reads:

[…] Unable to enter the cave, the old Bull turned swiftly and saw Eight Rules and Pilgrim rushing toward him. He became so flustered that he abandoned his armor and his iron rod; with one shake of his body, he changed into a swan and flew into the air.

[…]

Putting away his golden-hooped rod, the Great Sage shook his body and changed into a Manchurian vulture, which spread its wings and darted up to a hole in the clouds. It then hurtled down and dropped onto the swan, seeking to seize its neck and peck at the eyes. Knowing also that this was a transformation of Pilgrim Sun, the Bull King hurriedly flapped his wings and changed himself into a yellow eagle to attack the vulture. At once Pilgrim changed himself into a black phoenix, the special foe of the yellow eagle. Recognizing him, the Bull King changed next into a white crane which, after a long cry, flew toward the south. Pilgrim stood still, and shaking his feathers, changed into a scarlet phoenix that uttered a resounding call. Since the phoenix was the ruler of all the birds and fowl, the white crane dared not touch him. Spreading wide his wings, he dived instead down the cliff and changed with one shake of the body into a musk deer, grazing rather timorously before the slope. Recognizing him, Pilgrim flew down also and changed into a hungry tiger which, with wagging tail and flying paws, went after the deer for food. Greatly flustered, the demon king then changed into a huge spotted leopard to attack the tiger. When Pilgrim saw him, he faced the wind and, with one shake of his head, changed into a golden-eyed Asian lion, with a voice like thunder and a head of bronze, which pounced on the huge leopard. Growing even more anxious, the Bull King changed into a large bear, which extended his paws to try to seize the lion. Rolling on the ground, Pilgrim at once turned himself into a scabby elephant, with a trunk like a python and tusks like bamboo shoots. Whipping up his trunk, he tried to catch hold of the bear (Wu & Yu, 2012, vol. 3, pp. 156-157).

This fight shows that Sun Wukong learned a lot from his encounter with Erlang, for his transformations are far more fierce in comparison.

Archive #32 – The Precious Scroll of Erlang (Erlang baojuan) (1562)

The Precious Scroll of Erlang (Erlang Baojuan, 二郎寳卷; full name Qingyuan Miaodao Xiansheng Zhenjun Yiliao Zhenren huguo youmin zhongxiao Erlang Baojuan, 清源妙道顯聖真君一了真人護國佑民忠孝二郎開山寶卷), is an important baojuan from the 1560s that contains the heroic deeds of the immortal Erlang (二郎) (fig. 1), including his defeat of Sun Wukong (PDF page 46). This shows that the Monkey King was mentioned in a religious context 30 years before the standard Ming edition of Journey to the West (Xiyouji, 西遊記, 1592) was even published. Therefore, apart from recording the religious story of Erlang, it adds to that of Sun Wukong.

I must thank Dr. Benjamin Brose for sending me a PDF of the scroll. I’m excited to archive it on my blog for other scholars to access and read.

Fig. 1 – A relief carving of Erlang as Yang Jian (楊戩) from Investiture of the Gods (c. 1620) (larger version).

Scroll description:

In 1562 a text entitled Erlang baojuan (Precious scroll on Erlang) appeared, providing further information on the emerging Eternal Mother myth. Based on the story of Erlang’s valiant fight with the Monkey King, a famous and entertaining episode from the classic novel Journey to the West (which, incidentally, was given the finishing touches around the same time), the Erlang baojuan describes the final subjugation of the Monkey King by the semidivine Erlang, thanks in large measure to the assistance provided by the Eternal Mother. This text also seems to presage the legend surrounding the building of the Baoming Si, Temple Protecting the Ming dynasty, as described hereafter. In it the story of the bodhisattva Guanyin incarnating as a nun by the name of Lü is first being told. According to this text, the nun had tried unsuccessfully to dissuade Emperor Yingzong from fighting the Oirat Mongols prior to his debacle at Fort Tumu in 1449. When Yingzong was restored to the throne in 1457 after his long captivity, he rewarded the nun for her loyalty and courage and built a temple for her, naming it the Baoming Si. The temple had been reportedly in existence since 1462. By the late years of the Jiajing reign (1522–1567), however, it came under the sway of believers of the Eternal Mother religion (Shek & Tetsuro, 2004, p. 252).

Archive #31 – The Original 1592 Edition of Journey to the West, Complete with Pictures

I’m proud to present a PDF of the original edition of Journey to the West anonymously published in 1592 by the Shidetang (世德堂, “Hall of Generational Virtue”) publishing house of Jinling (金陵, “Gold Hill,” a.ka. Nanjing). Titled Newly Printed, Illustrated, Deluxe and Large Character, Journey to the West (Xinke chuxiang guanban dazi Xiyou ji, 新刻出像官板大字西遊記), it features 20 scrolls and 100 chapters (minus the current chapter nine). It contains many charming woodblock prints depicting the events described in the story. For example, this print shows the battle between Monkey and Nezha in their three-headed and six-armed forms.

One doctoral thesis shows that this version is based on an earlier edition of the story titled Newly printed, Completely Illustrated, Chronicle of Deliverances in Sanzang of the Tang’s Journey to the West (Xinqie quanxiang Tang Sanzang Xiyou shi ni (e) zhuan, 新鍥全像唐三藏西遊释尼(厄)傳) in ten scrolls (with three to ten chapters each) by Zhu Dingchen (朱鼎臣) of Yangcheng (羊城, i.e. Guangzhou).

The PDF is quite large at 1.5 gigs, so it will take time to download. I’ve provided two options.

Archive #29 – Ruthless Compassion: Wrathful Deities in Early Indo-Tibetan Esoteric Buddhist Art (1999)

I consider one of my greatest accomplishments on this blog to be discovering the origin of Sun Wukong’s golden headband. This would not have been possible without reading about the Hevajra Tantra (8th-century) in Robert Nelson Linrothe’s (1999) Ruthless Compassion: Wrathful Deities in Early Indo-Tibetan Esoteric Buddhist Art. This amazing study analyzes Esoteric Buddhist statues and texts to trace the evolution of these guardians from mere dwarf attendants to mighty warrior gods endowed with the power of the Five Wisdom Buddhas. This is a great resource for anyone researching religious art involving wrathful guardians in Buddhism, Daoism, and of course Chinese folk religion, for the iconography of these divine warriors spread far and wide.

I am sharing a PDF of the book found on libgen for the benefit of other scholars. The black and white portions of the book appear to be based on a xeroxed copy. However, there are full color plates in the back.

Book description:

Buddhists believe that the wrathful spirits represent inherent qualities of our own, and that meditating on them can transmute the otherwise malevolent sides of our own natures into positive qualities and actions. The wrathful deities also provide precious clues as to the early development of esoteric Buddhism in India, about which few early texts survive. Through careful examination of a large body of images as well as Sanskrit, Tibetan, and Indic texts, this lavishly illustrated volume traces the evolution of the forms and the unfolding significance of the wrathful deity in esoteric Buddhist sculpture.

The Tightening Spell of Sun Wukong’s Golden Headband

Last updated: 01-27-2022

Sun Wukong‘s golden headband (jingguquan, 金箍圈) (fig. 1) is an instantly recognizable part of his popular iconography. Anyone who’s read Journey to the West (Xiyouji, 西遊記, 1592) will know that it painfully tightens around our hero’s skull to correct any unsavory behavior. “What kind of behavior?” someone might ask. Well, mass murder, of course! In chapter 56, for example, Monkey’s Buddhist master Tripitaka recites the spell to punish him for beating a group of bandits to death with his magic staff and beheading one of them with a blade (Wu & Yu, 2012, vol. 3, p. 89).

Fig. 1 – A modern replica of Monkey’s golden headband (larger version).

This spell is first revealed to the monk by Guanyin in chapter 14:

I have a spell which is called the True Words for Controlling the Mind [dingxin zhenyan, 定心真言], or the Tight-Fillet Spell [jingu er zhou, 緊箍兒咒]. You must memorize it secretly; commit it firmly to your memory, and don’t let anyone learn of it […] When [Sun Wukong] returns, give him…the cap [containing the headband] to wear; and if he again refuses to obey you, recite the spell silently. He will not dare do violence or leave you again” (Wu & Yu, 2012, p. 317).

You can see the exact words are never revealed. This is not surprising, though, as the spell is one of the few things in the entire Buddho-Daoist cosmos that can control Sun Wukong. Tripitaka’s life would be in danger and the journey would be doomed if any villains got ahold of this secret. But … what if … we could guess the spell, just for fun? I’d like to suggest a mantra based on historical religious beliefs and iconography. This thought experiment was written for the benefit of artists and fanfiction writers looking to create more accurate portrayals of the novel and its characters.

I. The Band’s Religious Background

As I note in this article, the golden fillet is based on a ritual headband worn by Buddhist ascetics in ancient India. The Hevajra Tantra (Dabei kongzhi jingang dajiao wang yigui jing, 大悲空智金剛大教王儀軌經, 8th-c.) states yogins must wear the band and a list of other prescribed ritual items in their worship of the wrathful protector deity Heruka (Linrothe, 1999, p. 250). Most importantly, the tantra states the band symbolizes the Buddha Akshobhya (Ch: Achu, 阿閦; Budong, 不動; lit: “Immovable”) (fig. 2), who gained enlightenment through moralistic practices of right speech and action (Linrothe, 1999, p. 251; Buswell & Lopez, 2013, p. 27).

Fig. 2 – A depiction of Akshobhya (larger version). [1] Artist unknown.

Akshobhya and the other esoteric Wisdom Buddhas are sometimes depicted as small figures or colored jewels in the headdress of the Manjusri Bodhisattva (and other Buddhist personages) (Getty, 1914/1988, p. 37; Vessantara, 1993, p. 155). Akshobhya is symbolized by the color blue (Getty, 1914/1988, p. 36). A cursory Google image search shows the blue jewel is often set in the top most position over Manjusri’s forehead (fig. 3).

This might suggest a more religiously accurate version of Sun Wukong’s golden headband would include a figure or jewel representing Akshobhya.

Fig. 3 – A modern painting of Manjusri by Ben Christian (larger version). Image found here

II. The Mantra

Given the above information, I’d like to suggest the tightening spell for Monkey’s headband—within the context of our thought experiment—is the Akshobhya Mantra! There are two kinds. I’ll leave it up to you which one you like best. The first is a short recitation of the buddha’s name: O a kṣo bhya hūṃ (fig. 4). This can be very roughly translated as “Praise to the Immovable One!”. Om and Hum are both holy syllables invoking spiritual power and enlightenment, respectively. They also appear in the more well-known Oṃ maṇi padme hūṃ (Ch: An mo ni ba mi hong, 唵嘛呢叭咪吽). One Chinese version of the name mantra appears to be “An a bie zha zhi ga hong hong” (唵 阿別炸枝嘎 吽吽).

Fig. 4 – The Siddham and Uchen script versions of the short mantra (larger version). Based on information found here. Fig. 5 – A version of the longer chant with Uchen script, as well as English and Chinese transliterations (larger version). Based on an image found here.

The second is a longer chant, again called the “Mantra of Akshobhya” (Achu fo xinzhou, 阿閦佛心咒) (fig. 5 and video 1). It’s interesting to note that the historical Xuanzang (on whom Tripitaka is based) is known to have translated a version of this mantra. [2]

Reciting this to rein in Sun Wukong not only references the band’s historical and religious connection to Akshobhya but also serves as a physical reminder of right speech and action (how the deity gained buddhahood). It’s Tripitaka’s way of screaming, “Stop murdering everyone within arm’s reach!”

Update: 01-24-22

The DC Comics’ story “The Monkey Prince Hates Superheroes” presents the spell as the Nianfo (fig. 6).

Fig. 6 – Shifu Pigsy (a.k.a. Zhu Bajie) reciting “Amituofo” to activate the golden headband on the Monkey Prince, son of the original Monkey King (larger version). From Yang, 2021, p. 80. Copyright DC Comics.


Update: 01-25-22

The case for Akshobhya’s mantra being the tight-fillet spell is strengthened—again, within the context of our thought experiment—by the fact that he has power over strong negative emotions. According to Bangdel and Huntington (2003): “The transcendental insight represented by Akshobhya is mirrorlike wisdom (adarsha jnana), which…is the antidote to the poison of anger, or hatred” (p. 91). The monk Tripitaka assuages these emotions by activating the golden headband, once again reminding Wukong of right speech and action.

In addition, Akshobhya and Gautama have matching iconography: both are shown seated with the left hand palm up on the lap and the right reaching down to touch the earth. Hinayana Buddhists of Sri Lanka and Southeast Asia worship Gautama in this form, but Mahayana worships Akshobhya as such (see note #1). This is important as Gautama gives the three golden headbands to Guanyin in order to pacify any demons that she might encounter during her search for the scripture pilgrim (Wu & Yu, 2012, vol. 1, pp. 206-207). This shows there is a connection between the two Buddhas, and it also explains why Gautama would gift a headband associated with Akshobhya.


Update: 01-27-22

Various online sources and adaptations sometimes refer to the spell as the “Headache Sutra” (for example). But to my knowledge it’s never explicitly called this in the novel. The pain associated with the spell is generally used as a threat. For example, in chapter 16, Tripitaka exclaims: “Monkey! Aren’t you afraid of your headache [ni toutong, 你頭痛]? Do you still want to behave badly? (Wu & Yu, 2012, vol. 1, p. 347) (emphasis mine).

Chapter 25 provides two more names for the spell:

There is, moreover, the Tight-Fillet Spell or the Tight-Fillet Sutra [jingu er jing, 緊箍兒經]. It’s also [Tripitaka’s] “Old Saying Sutra” [jiuhua er jing, 舊話兒經]. [3] The moment he recites that, I’ll have a terrible headache, for it’s the magic trick designed to give me a hard time (Wu & Yu, 2012, vol. 1, p. 468).

Note:

1) Akshobhya’s iconography is as follows:

[He] is represented seated, like all the Dhyani-Buddhas, with the legs locked and both feet apparent. There are often wheels marked on the soles of his feet, or a protuberance like a button, resembling the urna on the forehead. His left hand lies on his lap in ‘meditation’ mudra. His right touches the earth with the tips of the outstretched fingers, the palm turned inward. This is called the bhumisparsa or ‘witness’ mudra.

The Hinayana Buddhists in Ceylon, Java, Burma, and Siam worship Gautama Buddha under this form, while those of the Mahayana school look upon it as Akshobhya; for, with but rare exceptions, the historic Buddha is only appealed to by the Northern Buddhists in his ethereal form of Amitabha.

Akshobhya may also take in Tibet another form of Gautama Buddha called ‘Vajrasana’ (diamond throne). The attitude is the same as the above, but before him on the lotus throne lies a vajra, or it may be balanced in the palm of the left hand lying in ‘meditation’ mudra on his lap (Getty, 1914/1988, p. 36).

2) The Chinese source refers to Akshobhya as the “Immovable Buddha” (Budong rulai, 不動如來).

3) I’ve added an extra sentence from the Chinese original glossed over in the translation. Yu (Wu & Yu, 2012) translates the spell as the “Old-Time Sutra” in a previous sentence (vol. 1, p. 468).
