The Monkey King is famous for utilizing a vast arsenal of magic powers to protect the monk Tripitaka on the journey to India, chief among them being immortality, shape-shifting, hair clones, super strength, and flight via the cloud somersault (jindou yun, 觔/筋斗雲). The latter is a powerful skill because it enables him to travel 108,000 li (33,554 mi / 54,000 km), [1] or one and one-third the circumference of our Earth, in a single leap. [2] Perhaps the most famous episode involving the somersault appears in Journey to the West (Xiyouji, 西遊記, 1592; “JTTW” hereafter) chapter seven when the Buddha bets Wukong that he’ll give the rebellious monkey the throne of heaven if he can leap clear of the Enlightened One’s palm. Sun gleefully accepts, certain of his success:
What a fool this Tathagata is! A single somersault of mine can carry old Monkey one hundred and eight thousand li, yet his palm is not even one foot across. How could I possibly not jump clear of it? (Wu & Yu, 2012, vol. 1, p. 194).
But of course lovers of the novel know how this wager ends, with a desecrated finger and our hero trapped beneath Five Elements Mountain.

1. Literary Description
While Sun is traditionally portrayed in visual media riding a single cloud (fig. 1), the very name “somersault” points to Monkey leaping from cloud to cloud. And in fact this is demonstrated in chapter 97 when it requires “a series of cloud somersaults” for him to retrieve the soul of an elderly benefactor from the underworld (Wu & Yu, 2012, vol. 4, p. 338). However, the magic skill’s attributes are not always portrayed consistently throughout the novel. For example, it is sometimes shown capable of transporting passengers, such as the “thirty or fifty” of Monkey’s children rescued from captivity in JTTW chapter two, thereby implying a single cloud (Wu & Yu, 2012, vol. 1, p. 129). (See the 04-28-26 update below for more info.) But other times, like in chapter 22, it can’t lift even a single person because the impure nature of mortals renders them “as heavy as the Tai Mountain” (Wu & Yu, 2012, vol. 1, p. 427). Interestingly, the somersault is portrayed as much faster than the clouds of other immortals (see section three below).

2. Ties to Daoist immortals
Sun Wukong first learns to perform his cloud somersault in chapter two while studying Daoist cultivation under his first master, the Sage Subodhi:
[T]he Patriarch gave him an oral formula, saying,
“Make the magic sign, recite the spell, clench your fist tightly, shake your body, and when you jump up, one somersault will carry you one hundred and eight thousand miles.” When the other people heard this, they all giggled and said, “Lucky Wukong! If he learns this little trick, he can become a dispatcher for someone to deliver documents or carry circulars. He’ll be able to make a living anywhere!”
The sky now began to darken, and the master went back to the cave dwelling with his pupils. Throughout the night, however, Wukong practiced ardently and mastered the technique of cloud-somersault. From then on, he had complete freedom (emphasis added), blissfully enjoying his state of long life (Wu & Yu, 2012, vol. 1, p. 123).
Elements of this passage reference the long tradition of cloud-borne transcendents in Daoist literature. For example, Kirkova (2016) highlights a poem by the first Cao Wei emperor Cao Pi describing the great speed of their travel: “Lightened you’ll soar, mount the floating clouds, / in a blink you’ll travel millions of li” (p. 105). She explains the ability to traverse vast distances in a flash “is a primary sign of the immortals’ mastery over space and time and is an important topos in their hagiographies” (Kirkova, 2016, p. 106). Furthermore, Kirkova (2016) points out the term used to denote their great freedom of movement, xiaoyao (逍遙/消搖), emphasized above, appears in works as old as the Huananzi and Zhuangzi (p. 104).
3. Ties to Chan Buddhist Philosophy
Despite the cloud’s apparent ties to Daoism, it has a strong symbolic connection to Buddhism. For example, the distance that a single somersault covers just so happens to correspond to the expanse separating Tripitaka from the Buddha’s paradise. This fact is revealed in chapter 14 by Guanyin while disguised as an old woman: “The Buddha of the West … lives in the Great Temple of Thunderclap in the territory of India, and the journey there is one hundred and eight thousand li long” (Wu & Yu, 2012, vol. 1, p. 316).
Shao (2006) explains that the distance is taken directly from the Platform Sutra (Liuzu tangjing, 六祖壇經, c. 8th to 13th century) of Huineng, the sixth patriarch of Chan Buddhism (p. 718). The particular passage reads:
The governor also asked,
I often see clergy and laity invoking Amitabha Buddha in hopes of rebirth in the [Pure Land of the] West. Please explain this to me. Can we attain rebirth there? Please resolve this doubt for me.
The Master said,
Listen clearly, Governor, and I will explain it to you. When the World Honored One was in the city of Sravasti, he spoke of the Western Pure Land as a teaching device. Scripture is clear that “it is not far from here,” but treatises say it is “108,000 li away.” This number refers to the ten evils and eight wrongs in the one’s person. This says it is far away. Saying it is far away is for people of lesser faculties. Saying it is near is for people of better faculties.
刺史又問曰：「弟子常見僧俗念阿彌陀佛，願生西方。請和尚說，得生彼否？願為破疑。」
師言：「使君善聽，惠能與說。世尊在舍衛城中，說西方引化。經文分明，去此不遠。若論相說，里數有十萬八千，即身中十惡八邪，便是說遠。說遠為其下根，說近為其上智。
[…]
Now I urge you, good friends, to first get rid of the ten evils; that is the equivalent of traveling one hundred thousand li. [3] Then get rid of the eight wrongs; that is the equivalent of crossing eight thousand li. See essential nature in every moment, always acting with impartial directness, and you will arrive in a finger-snap and see Amitabha Buddha (Huineng & Cleary, 1998, pp. 26-27).
As can be seen, the number 108,000 is symbolic of two sets of spiritual hindrances. The “ten evils” (shi’e, 十惡) are killing, stealing, sexual misconduct, greed, hatred, delusion, foul language, lying, harsh speech, and slander. The “eight wrongs” (baxie, 八邪) are opposites of the eight fold path (Huineng, Hsuan, & Buddhist Text Translation Society, 2002, p. 183). Ridding oneself of these piecemeal gets you many li closer to paradise. But only those who achieve enlightenment can arrive instantly. This means the cloud somersault can be read as a Chan metaphor for instant enlightenment. After all, Monkey can travel to the Buddha’s heaven in a flash, whereas Tripitaka is fated to journey thousands of miles over many years “before he finds deliverance from the sea of sorrows” (Wu & Yu, 2012, vol. 1, p. 436). This is because, as suggested by Shao (2006), the demons encountered on the journey embody the “ten evils and eight wrongs” that must be defeated before the monk can enter paradise (p. 719).

This connection to Buddhism may then explain why the novel differentiates Monkey’s somersault (fig. 2) from the clouds of other immortals. As Sun explains in chapter 22: “My cloud somersault is essentially like cloud soaring [jiayun, 駕雲] … the only difference being that I can cover greater distances more rapidly” (Wu & Yu, 2012, vol. 1, p. 427). In light of the Chan evidence, the difference in speed could be read as a further metaphor for the potency of Buddhism over Daoism.
4. Other Influences?
Going back to the early days of Sun’s flight training, Subodhi observes our hero using an unorthodox method for propelling himself into the sky: jumping. This differs from other immortals, so the Sage teaches him a different method:
The Patriarch said, “When the various immortals want to soar on the clouds, they all rise by stamping their feet. But you’re not like them. When I saw you leave just now, you had to pull yourself up by jumping. What I’ll do now is to teach you the cloud-somersault in accordance with your form” (Wu & Yu, 2012, vol. 1, p. 123).
Zhou (1994) suggests this method is likely based on “the novelist’s personal observation” of trained monkey street performances “in the late Ming marketplace” (fig. 3 and 4) (p. 71). He points to an episode in chapter 28 when Wukong returns home to learn his children are regularly captured to perform tricks in the human world:
Those of us who were caught by the net or the trap would be led away live; they would be taught to skip ropes, to act, to somersault, and to do cartwheels. They would have to beat the drum and the gong on the streets and perform every kind of trick to entertain humans (Zhou, 1994, p. 71; cf. Wu & Yu, 2012, vol. 2, p. 31).
Anyone who has viewed monkeys in a zoo or in the wild knows that they are naturally gifted acrobats. Therefore, Zhou’s proposal is certainly an alluring possibility, one that mixes the naturalistic and historical with Daoist tales of cloud-borne immortals.

Scholars favoring a foreign origin for Sun sometimes point to the somersault as evidence for his connection to the Hindu monkey god Hanuman from the epic Ramayana (4th/5th century BCE). For example, Mi (as cited in Mair, 1989) notes similarities in which Sun and the god propel themselves by leaping:
In typical Chinese legends, the spirits and immortals mount on clouds and ride them; they stand on top of the clouds. Sun Wukong, however is different … Rather, he leaps through the air from a crouching position in the same fashion as Hanuman … This proves Sun Wukong’s supernatural abilities were adopted from Hanuman. (pp. 712-713).
Walker (1998) champions this view by citing a passage from the Ramayana in which Hanuman’s mighty leap across the sea from India to Lanka rips trees away from a mountain:
Hanuman, the foremost of monkeys, without pausing for breath … sprang into the air and, such was the force of his leap, that the trees growing on the mountain, tossing their branches, were sent spinning on every side.
In his rapid flight, Hanuman bore away those trees with their flowering boughs filled with lapwings intoxicated with love … Carried away by the impetus of his tremendous bound, those trees followed in his wake, like an army its leader (p. 10).
However, I’m inclined to believe any similarities in propulsion are simply the product of common behavioral traits among monkeys (refer back to my statement above about their gift for acrobatics). If Wukong’s jumping is indeed based on the somersaulting monkeys of vaudevillian street performances in China, then Hanuman’s jumping prowess no doubt has a real world counterpart in India. A prime example is the Gray Langur, which is capable of spectacular leaps (video 1).
Video 1 (LOUD NOISE WARNING) – A Langur takes a mighty jump. The video should start at minute 0:43.
Given the somersault’s symbolic connection to Chan Buddhism, it’s possible Monkey’s jumping has ties to the religion as well. Like immortals, Buddhist saints are also portrayed in Chinese literature as having the power of flight. One example is Maudgalyayana (Ch: Mulian, 目連), a disciple of the Buddha, who is famous for appearing in a late-9th to early-10th century Bianwen (變文) text in which he travels to the underworld to release his mother from karmic torment (fig. 5). One passage from the tale reads:
Maudgalyayana awoke from abstract meditation,
Then swiftly exercised his supernatural power;
His coming was quick as a thunderclap,
His going seemed like a gust of wind.
[…]
With his supernatural power, he gained freedom,
So he hurled up his begging bowl and leaped into space (emphasis added);
Thereupon, instantaneously,
He ascended to the heavenly palace of Brahma (Mair, 1994, pp. 1097-1098).
Like Monkey, Maudgalyayana is depicted leaping into the heavens to freely roam the cosmos at blinding speeds, the only difference being that he stands astride a magic alms bowl (fig. 6) and not a cloud. It’s important to note that the saint’s tale influenced the 13th century precursor of the Ming JTTW. As I show in this article, Sun’s antecedent, the Monkey Pilgrim (Hou xingzhe, 猴行者), serves as a proxy for the saint because he wields magic weapons based on those used by Maudgalyayana, namely a golden-ringed monk’s staff and an alms bowl. The ringed staff would come to influence Sun’s signature weapon in JTTW, including its ability to change size and pick locks. Therefore, it’s possible the saint may have also influenced Monkey’s jumping.

5. Popular Culture
It’s interesting to note that the cloud somersault was adapted in the world famous Dragon Ball franchise. In episode three of the Dragonball anime, the lead character Son Goku, himself based on Sun Wukong, is gifted the yellow, fluffy Kinto’un (筋斗雲) by his would-be martial arts teacher, Master Roshi. [4] This is an obvious reference to Subodhi teaching the somersault skill to Monkey. But before Goku officially takes possession, Roshi gives him a warning: “People with impure thoughts can’t ride on it. In other words, you have to be a good person” (video 2). The master thereafter attempts to stand on it but quickly falls through due to his perverted nature. Goku then leaps up and successfully lands on the cloud, proving his worth. This exchange is no doubt a reference to Sun’s inability to carry passengers on his cloud because the impure nature of mortals renders them too heavy (see section one).

6. Conclusion
The Monkey King first learns the cloud somersault during the early days of his Daoist training under the Sage Subodhi. It enables him to travel 108,000 li in a single leap, making him much faster than the cloud soaring of other transcendents. While this skill shares affinities with the fleet clouds of immortals from Daoist hagiography, Sun’s somersault has a deep connection to Chan Buddhism. The vast distance that it travels is symbolic of the “ten evils and eight wrongs,” two sets of spiritual hindrances from the Platform Sutra said to keep the Buddha’s paradise out of reach. Only those who cleanse themselves of these obstacles can achieve enlightenment and arrive there in a flash, thus making Wukong’s cloud an apt metaphor for instant enlightenment. This suggests the greater speed of the somersault can be read as a further metaphor for the potency of Buddhism over Daoism.
Wukong’s habit of jumping into the heavens differs from the way other immortals rise by stamping their feet. This unorthodox method may have naturalistic or even religious influences. The suggestion that it is based on somersaulting monkeys from Chinese vaudevillian street performances is alluring given their natural gift for acrobatics. Some scholars champion a foreign origin by pointing to the leaping prowess of the Hindu monkey god Hanuman. But this could simply be a passing similarity based on common behavioral traits among monkeys. The jumping may also have ties to the Buddhist saint Maudgalyayana, who is portrayed in a famed 9th/10th century tale leaping into the air to ride his magic alms bowl between heaven and hell. Elements from his story would come to influence the 13th century precursor of JTTW, as well as the Ming edition of the novel, adding support for his possible influence.
7. Updates
Update: 01-04-24
The singular version of Monkey’s cloud is sometimes described as being “auspicious” (xiangyun, 祥雲) or having a “luminosity” (xiangguang, 祥光). Such clouds or lights are commonly associated with the five colors (wuse, 五色) (fig. 7). Chapter 88 makes this explicit:
Marvelous Great Sage! With a loud whistle he somersaulted right up into midair, his two feet treading the auspicious cloud of five colors (emphasis added). At about three hundred paces above ground, he let loose his rod to make [the martial arts moves] Sprinkling Flowers over the Top and the Yellow Dragon Entwining the Body. Up and down he moved, circling left and right. In the beginning his person and the rod so complemented each other that they seemed, as the adage had it, like flowers added to brocade. By and by even the person disappeared, and all one could see was a sky full of twirling rods! (Wu & Yu, 2012, vol. 4, pp. 196-197)
好大聖，唿哨一聲，將觔斗一抖，兩隻腳踏著五色祥雲，起在半空，離地約有三百步高下。把金箍棒丟開個「撒花蓋頂」，「黃龍轉身」，一上一下，左旋右轉，起初時人與棒似錦上添花；次後來不見人，只見一天棒滾。
Fig. 7 – An example of an auspicious cloud (larger version). The scientific term for this phenomenon is “cloud iridescence,” but such nimbuses are commonly called “rainbow clouds” in English.
Update: 04-28-26
Above, I wrote: “[The cloud] is sometimes shown capable of transporting passengers, such as the ‘thirty or fifty’ of Monkey’s children rescued from captivity in JTTW chapter two, thereby implying a single cloud” (Wu & Yu, 2012, vol. 1, p. 129).
However, this was a mistake on my part. As I show in my more recent catalog of Sun Wukong’s powers and skills, these children are actually transported via the “magic of displacement” (shefa, 攝法), a swift, powerful wind appearing in JTTW chapters 2, 3, 62, 71, and 84.
On a different note, I feel like a major aspect of the somersault cloud needs extra context. If you recall in section 3, I discussed how the figure of 108,000 li is a religious allegory for the distance separating man from the Buddha’s paradise. Per the Sixth Chan Patriarch, the number comprises the “ten evils” (shi’e, 十惡) and “eight wrongs” (baxie, 八邪), two lists of negative thoughts and actions that hinder spiritual cultivation. Anyone who manages to rid themselves of these will attain enlightenment, allowing them to travel to the holy land instantly. But not everyone is capable of defeating these spiritual hindrances, so the distance separating them from the Buddha might as well be infinity. Therefore, it’s not wise to assign a real world distance and speed to the somersault cloud. This is regarding my recent response to “powerscaling.”
Update: 05-03-26
Here is an old woodblock print showing Monkey practicing his cloud somersault above Patriarch Subodhi and his early religious brothers (fig. 8). It is one of a few images from The Book to Enlightenment of the Journey to the West (Xiyou Zhengdao Shu, 西遊證道書, 1663), a Daoist commentary on the novel.

Notes:
1) The li (里) is a Chinese measure equaling roughly one-third of a mile. All cited English translations presented here use “mile” instead of the original li. I have, therefore, changed them accordingly.
2) Of course the magic world in which Monkey lives is not our own. It is much, much larger.
3) The English translation originally says “ten myriad” (Huineng & Cleary, 1998, pp. 26-27). The original Chinese reads shiwan (十萬; 10 x 10,000), or 100,000. I have changed the source to make this more explicit.
4) The cloud is called the “Flying Nimbus” in the English dub.
