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).

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).

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.

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).

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!”

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

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.

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).


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).
