Zuìshàng chéng lùn 最上乘論
Treatise on the Supreme Vehicle
“Treatise on the Supreme Vehicle” — the foundational meditation-instruction treatise of early Chán’s “East Mountain teaching” (Dōngshān fǎmén 東山法門), transmitted under the alternative title Xiūxīn yào lùn 修心要論 (“Essentials of Cultivating the Mind”); attributed (shù 述) to the Fifth Patriarch Hóngrěn 弘忍 (602–675) of the Huángméi 黃梅 Dōngshānsì 東山寺, though possibly a text compiled by his disciples in the decades after his death
About the work
A single-juan early-Chán meditation treatise in question-and-answer format, articulating the shǒu xīn 守心 (“guarding the mind”) practice that is the signature teaching of the East Mountain school. Taishō T48 n2011. The text opens: “Xiū xīn yào lùn: ruò qí bù hù jìng zhě, yíqiè xíng wú yóu qǔ jiàn” (“Essentials of cultivating the mind: if you do not protect purity, there will be no means for any practice to bring about insight”), immediately giving the alternative title under which the treatise widely circulates in the Dūnhuáng manuscript tradition. The opening position: xiūdào zhī běntǐ xū shí dāng shēn xīn běn lái qīngjìng bùshēng bùmiè wúyǒu fēnbié, zìxìng yuánmǎn qīngjìng zhī xīn, cǐ shì běnshī, nǎi shèng niàn shífāng zhū fó — one must recognise that the body-and-mind are originally pure, unborn-and-undying, without discrimination, the self-nature’s complete-and-pure-mind; this is the original teacher, surpassing recollection of the Buddhas of the ten directions.
Doctrinally the text is structured around a set of Q-and-A pairs expanding this opening position: how is it known that one’s own mind is originally pure? (A: the Shí dì jīng / Daśabhūmika sūtra says all beings have the jīn’gāng fóxìng — diamond-buddha-nature — within, merely obscured by the “black clouds” of the five skandhas, but the diamond itself is indestructible); how is it known that one’s own mind is unborn-and-undying?; why is one’s own mind called the “original teacher”?; why is preserving the original mind superior to recollection of the Buddhas? — through several dozen successive topics, all turning on the shǒu běn zhēn xīn 守本真心 (“guarding the original true mind”) practice. Non-commentarial; commentedTextid omitted.
Tiyao
Not a WYG text; no 四庫 tíyào exists. Opening credit line reads dìwǔ zǔ Hóngrěn chánshī shù 第五祖弘忍禪師述 (“composed by the Fifth Patriarch, Chán Master Hóngrěn”). The text’s own opening sentence functions as preface: “yuàn shànzhīshí, rú yǒu xiě zhě, yòng xīn wú lìng tuō cuò, kǒng wù hòurén 願善知識如有寫者，用心無令脫錯，恐誤後人” (“my wish to good-learning-friends: if you copy this, use your mind so as not to err, lest you mislead later students”). This internal address to the reader-copyist reflects the text’s primary medium of transmission through hand-copied manuscripts circulating within and beyond the monastic training setting.
Abstract
The Zuìshàng chéng lùn / Xiūxīn yào lùn is among the most important surviving primary sources for pre-Shénxiù / pre-Huìnéng Chán, documenting the doctrinal world of the East Mountain school in the mid-to-late 7th century. The Fifth Patriarch Hóngrěn 弘忍 (DILA A000237: born 602, died Shàngyuán 2.10.23 = 18 November 675, aged 74), based at the Huángméi Dōngshān sì in Qízhōu 蘄州, inherited the abbacy from 道信 Dàoxìn in Yǒnghuī 2 (651) and taught there until his death; Hóngrěn’s assembly included both 神秀 Shénxiù (606–706) — subsequently the founding figure of the Northern School — and 惠能 Huìnéng (638–713) — subsequently the founding figure of the Southern School. The Dōngshān fǎmén 東山法門 under Hóngrěn was the single largest monastic training institution of its period (recorded as comprising between five hundred and a thousand monks), and the doctrinal language of the Xiūxīn yào lùn — shǒu xīn 守心, shǒu běn zhēn xīn, níng rán shǒu xīn 凝然守心, the diamond-obscured-by-clouds metaphor — is the language that both later schools inherit.
The attribution of the text to Hóngrěn personally has been debated since the early 20th century. The Dūnhuáng manuscript tradition (multiple witnesses including Stein 2669, Pelliot 3434, and several BnF/Sengoku fragments) uniformly carries the attribution, but the language of the text — a finished literary-doctrinal treatise — is less likely the unmediated speech of a seventh-century Chán master than the product of a disciple’s editorial compilation. McRae (1986) argues for a composition by Hóngrěn’s senior disciples in the 675–725 window, as part of the post-Hóngrěn consolidation of the East Mountain teaching; Yanagida Seizan 柳田聖山 takes a similar position in Shoki zenshū shisho no kenkyū 初期禪宗史書の研究. The treatise subsequently circulated throughout Táng Chán — cited in Shénxiù-school and Southern-school texts alike — and the Dūnhuáng manuscript tradition is the principal route by which it survives into the Taishō edition.
Dating bracket: notBefore 675 (Hóngrěn’s death, as terminus post quem for post-Hóngrěn compilation; earlier if the text is indeed Hóngrěn’s own), notAfter 750 (terminus by which the text is solidly circulating, per Dūnhuáng manuscript evidence and early-Táng citation). The received Taishō text is based on the Dūnhuáng recension.

Other points of interest
The treatise’s shǒu xīn 守心 (“guarding the mind”) practice — treating the mind as an object to be watched, protected, and kept clear of defilements by sustained attentive vigilance — is the doctrinal target of the later Southern-School polemical tradition’s characterisation of “Northern-School” gradualism. The Dūnhuáng Platform Sūtra (KR6q0082) and later Southern-School texts explicitly reject the shǒu xīn formulation in favour of wúniàn 無念 (“no-thought”) and jiànxìng 見性 (“seeing-the-nature”), and the doctrinal tension between these two stances defines the eighth-century Chán polemical landscape. That the East Mountain school’s own foundational treatise is pejoratively characterised by its later opponents makes the Xiūxīn yào lùn the principal primary source against which the Southern-School positions are articulated.
The treatise’s language and structure — Q-and-A format, consistent doctrinal vocabulary, citation of a standard Mahāyāna scriptural canon (Shí dì jīng, Wéimó jié jīng, Jīn’gāng jīng, Lèngjiā jīng) — places it at the threshold of the yǔlù 語錄 genre: it is not yet a yǔlù (which would be a record of dialogues with a specific master’s distinctive voice and named disciples) but is one of the immediate generic antecedents of the eighth-to-ninth-century yǔlù development.
