Preface to the Samaya Precepts by 空海 (撰)
About the work
A single-fascicle doctrinal preface to the samaya-śīla — the esoteric Buddhist precepts that the candidate accepts at abhiṣeka — composed by Kūkai 空海 (774–835), founder of the Japanese Shingon school. The text is among the most concise and elegant of Kūkai’s writings: it presents the samaya precepts as the natural culmination of the ten-stage progression of mind (shí-zhù xīn 十住心) which Kūkai had set out at length in his Mì-zàng bǎo-yào 祕藏寶鑰 (= KR6m0021) and Shí-zhù xīn lùn 十住心論 (= KR6m0020).
Abstract
Authorship and dating: the header bears the signature “Biànzhào Jīngāng zhuàn” 遍照金剛撰 — “composed by Henjō Kongō,” Kūkai’s esoteric ordination name (Biànzhào Jīngāng = Sanskrit Vairocana Vajra). The text must postdate Kūkai’s articulation of the shízhù xīn doctrine (early 820s, the framework presupposed throughout); it falls within his mature compositional period 822–835.
Doctrinal content: the preface opens by contrasting the bewildering proliferation of Buddhist remedial teachings — “1,200 medicinal herbs, 72 species of golden elixir… twelve-part scriptures, 84,000 doctrinal treatises” — with the unifying samaya-śīla of Shingon, which is the precept of “Mahāvairocana’s self-nature Dharma-body teaching” (大毘盧遮那自性法身之所説眞言曼荼羅教之戒). Kūkai then maps each of the ten stages of mind onto a corresponding ethical-spiritual regimen: the five-relationships and five-precepts are the medicine of the Yú-tóng chí-zhāi xīn 愚童持齋心 (childish fasting); the six perfections and four meditations are the Yīng-tóng wú-wèi xīn 嬰童無畏心 (infantine fearlessness); the 250-precept code and four-contemplations belong to the Śrāvaka stage; and so on up to the 极無自性心 Jí wú-zì-xìng xīn (extreme no-self-nature) of Huayan, beyond which lies only the Shingon samaya. The candidate is then instructed to cultivate four initial mental dispositions — faith, great compassion, ultimate-meaning mind, and great bodhicitta — each broken down into ten sub-aspects (faith comprises purity, decisive resolve, joy, no-fatigue, sympathetic joy, reverence, conformity, praise, indestructibility, and love; etc.).
The structural logic is fully Kūkai’s: the samaya-śīla is neither an arbitrary set of monastic rules nor a mere “esoteric” supplement, but the natural culmination of the entire spectrum of Buddhist ethical cultivation, in which all preceding precepts are seen to be “lacking inherent nature, and so progressively elevated” (皆由無自性故展轉勝進) until they reach the Shingon samaya as their fulfillment.
