The Śūraṅgama Sūtra (Chinese Lengyan jing, Taishō no. 945) is a ten-roll Mahayana scripture that appeared in Chinese at Guangzhou in 705 CE and became one of the most commented-on texts in Chinese Buddhism. It opens with Ananda’s near-seduction, asks where the mind is, and carries the Śūraṅgama mantra. Its authenticity has been disputed since the eighth century.

This page gives the text: its setting, its passages in the sutra’s own order, how the two standard English versions differ, and the dispute as scholarship leaves it. For the wider library see Buddhist scriptures; for the school that made it central, Chan, Sŏn and Thiền.

What is the Surangama Sutra?

Its full Chinese title is a sentence: The Sutra of the Foremost Shurangama at the Great Buddha’s Summit Concerning the Tathagata’s Secret Cause of Cultivation, His Certification to the Complete Meaning and all Bodhisattvas’ Myriad Practices. Everyone shortens it. The earliest catalogue notice, by the bibliographer Zhisheng in 730, already records ten rolls (juan).

Its shape is unusual for a Mahayana sutra: it begins with an incident, not a cosmic vision. Ananda, the Buddha’s cousin and attendant, is caught by a mantra while begging alone, and Mañjuśrī is sent with a counter-mantra to fetch him back. Everything after that undoes the assumption Ananda made when he fell — that he knew his own mind.

It is not the Surangama Samadhi Sutra

Two texts carry the word śūraṅgama, “heroic march”. The Śūraṅgama-samādhi-sūtra is Taishō no. 642, translated by Kumārajīva, who died in 413; the sutra on this page is Taishō no. 945, which surfaced in 705, on a different subject. George Keyworth’s 2022 study warns in as many words that “T no. 945 should not be mistaken for T no. 642”.

The discourse, passage by passage

Every passage below is the Buddhist Text Translation Society’s English, quoted in the sutra’s own order with that edition’s line references. The text is long; this is a selection from it.

Ananda begs house to house in strict order, resolved to pass over neither the high-born nor the outcast: he does everything correctly and is undone anyway. Of all the disciples he is the one remembered for hearing and retaining the teaching — the faculty the sutra sets up to fail. The counter-mantra Mañjuśrī carries is the sutra’s own, arriving before any doctrine.

This opens what Chinese tradition calls the seven locations of the mind. Ananda answers: inside the body; outside it; concealed in the eye, like crystal bowls laid over it; seeing darkness with closed eyes is seeing within; wherever it meets things; in the middle; attached to nothing at all. Each is refused. The simile just before assumes a military fact — a king cannot send troops until he knows where the thieves are.

The listener is King Prasenajit, sixty-two, who has just conceded that the Ganges looked no different to him at three and at thirteen. The argument has a named target: Katyayana and Vairatiputra, the teachers he had met before the Buddha, who told him the body is annihilated at death. “The Seeing Nature” is the title this translation gives the whole chapter — and note the limit of the claim. The seeing does not wrinkle; the sutra does not say here that a self sits behind it, a distinction that matters whenever the passage is read as a statement about buddha-nature.

Twenty-five bodhisattvas and arhats each describe the sense-door by which they awakened; this is the last. The speaker is Guan Shi Yin — Guanyin — whose name the same translators render “Contemplating the World’s Sounds”. The sutra turns it into a method: turning the hearing back on itself until hearing and heard both drop away.

Mañjuśrī, asked to judge the twenty-five methods, answers in verse, turning each of the others aside with a version of one line — “How can this bring perfect penetration?” His reason for choosing the ear is regional, not absolute: the true teaching in this land resides in hearing.

The chapter this translation calls “The Three Non-Outflow Studies” turns practical, with four instructions the text names “clear and unalterable” — against lust, killing, stealing and lying, the last aimed at false claims of attainment. The one on killing has consequences: it revokes the Buddha’s earlier permission to eat “five kinds of pure meat”, and the next chapter, “The Three Gradual Stages”, forbids the five pungent plants — which is why East Asian Buddhists avoid onion and garlic.

The syllables in the middle are Chinese characters used for their sound alone, standing in for Sanskrit; the same community gives this mantra the full title “Great White Canopy of Light Dharani Mantra”. The sutra attaches practice to it: recite 108 times, build a ritual platform, keep it up for three weeks.

The Buddha says this as he is about to leave the Dharma seat, then turns back: the ending is an afterthought that runs to the close of the sutra. What follows are the fifty skandha-demon states, ten for each of the five aggregates — a sudden certainty of sagehood, an appetite for powers. Master Hsüan Hua counted this section, with the four decisive deeds and the twenty-five sages, among the parts of the sutra its critics could least bear.

Is the Surangama Sutra authentic?

This has been the live question for twelve hundred years. The Japanese monk Genei (d. 840), whose account both modern studies rely on, records that the sutra reached Japan in 754 and at once caused a debate about whether it was genuine; masters of the Sanron and Hossō schools were convened and concluded that “it is an authentic Buddhist scripture”. In the 770s a Japanese mission to the Tang court came home with the report that a lay Buddhist named Faxiang had said it was composed by Fang Rong — the exiled official whose name stands in its colophon as the man who wrote it down. In 779 a petition to destroy the sutra circulated among the temples of Nara; it was saved by the monk Kaimyō. Centuries later the Neo-Confucian Zhu Xi (1130–1200) put the suspicion bluntly: the sutra “was originally only a spell-text”, to which Fang Rong later added, in George Keyworth’s translation, “many discussion points about the natural ordering” of things.

Modern scholarship reopened the case in 1922 with the Japanese scholar Mochizuki Shinkō. Jia Jinhua’s 2022 survey lists those who followed him in calling the text a Chinese apocryphon — Lü Cheng, whose essay is titled One Hundred Reasons Why the Śūraṃgama-sūtra Is Apocryphal, Paul Demiéville and James Benn among them. Keyworth states the field’s position plainly: there are “three points of scholarly consensus among scholars of East Asian Buddhism regarding the apocryphal status of this scripture” — its provenance is dubious, the seventh roll’s dhāraṇī may or may not be apocryphal, and it “promotes ideas and practices that cannot easily be corroborated using Indian Buddhist textual precedents”. The objection is internal as much as documentary: the text reads, in Keyworth’s summary, “like a proper Chinese text”, carrying Chinese and Daoist turns of phrase. Waley, Demiéville and Benn have all called it a masterpiece of Chinese philosophy with a Buddhist flavour — praise and verdict in one phrase. Keyworth also unsettles the date on this page’s own opening line: because the monk Huaidi named in the earliest account was apparently working on another translation project between 705 and 713, he argues the sutra’s “translation and/or fabrication must have taken place after 713”.

The case is not closed. Ron Epstein argued in 1976 that the sutra may be authentic, raising an objection others have accepted: scholars count its agreements with other sutras as theft and its disagreements as invention, and both cannot be evidence. Jia, working from the Fangshan stone-canon version and Tang court chronology, concludes it was “likely a late Mahāyāna scripture composed by monk-scholar(s) residing in the Nālandā monastery” — translated, not forged.

The traditions that use the sutra accept none of this. Master Hsüan Hua (d. 1995), under whom the standard English translation was made, called the forgery charge a rumour started by demon kings and staked everything on it: “if the Shurangama Sutra were phony, then I would willingly fall into the hells forever through all eternity.” A religious judgement, not a historical one.

How the translations differ

Two English versions are standard: the Buddhist Text Translation Society’s, made in Hsüan Hua’s community, and Charles Luk’s (Lu K’uan Yü), which follows Chan master Han Shan’s late sixteenth-century commentary and carries his glosses in brackets.

The first row costs something. Luk restores the Indian name, Avalokiteśvara; the BTTS keeps the Chinese, Guan Shi Yin. Since the passage is about hearing, the Chinese name does work the Sanskrit cannot, and a reader given only Luk misses why the sutra assigns this bodhisattva this method. The second row shows each house’s habit: BTTS stays close and terse, Luk expands to explain. Both are translating a Chinese text.

How the Surangama Sutra is used today

The mantra outlived the argument. The community that produced the English translation calls it the king of mantras, “the longest and most important”, and the City of Ten Thousand Buddhas gives two hours every Saturday morning to a Śūraṅgama Mantra recitation for world peace — two hours of chanting one text.

Its dietary rule outlived it too: Chinese, Korean and Vietnamese monastics avoid the five pungent plants on this sutra’s authority. The Pali Canon imposes nothing of the kind on monks — its one rule touching garlic is a training rule for nuns about taking too much from a donor. And the sutra is still read as a manual: it sets out the fifty states so that a meditator can name one instead of being “engulfed by deviant views”, which is why the list still circulates where meditation goes wrong. Keyworth counts four commentaries in the Tang, twenty in the Song, four in the Yuan, thirty-four in the Ming and six in the Qing.
