Fóxìng guān xiūshàn fǎ 佛性觀修善法

The Method of Buddha-Nature Contemplation and Cultivation of the Good by 信行 (Xìnxíng, 撰); critical edition by 西本照真 (整理)

About the work

A Suí-period Chinese Buddhist treatise in one fascicle attributed to Xìnxíng 信行 (540–594), founder of the Sānjiējiào 三階教. A foundational Sānjiē text alongside KR6v0053 Dàshèng wújìnzàng fǎ and KR6v0052 Fóxìng wèndá (which itself contains a long Fóxìngguān xiūshàn fǎ 佛性觀修善法 section). The work expounds Sānjiē’s signature doctrines: fóxìngguān 佛性觀 (“contemplation of the Buddha-nature”), the universal Buddha-nature in all beings, and the practical xiūshàn fǎ 修善法 (“methods of cultivating the good”) that follow from this contemplation — including pǔjìng 普敬 (universal reverence — bowing to every passer-by as a future Buddha), rènè 認惡 (self-acknowledgment of evil), and the Chángbùqīngbóusà 常不輕菩薩 (Sadāparibhūta-bodhisattva) practice modelled on the Lotus Sūtra.

Abstract

Two Dūnhuáng manuscript witnesses survive at the National Library of China: Běidūn 07879 (zhì 制 79; microfilm 8386) — head damaged, tail intact, with damaged tail-cartouche reading □□guān xiūshàn fǎ (the first two graphs lost); and Běidūn 14802 (xīn 1002) — head intact, tail damaged. The two manuscripts are demonstrably copies of the same work: they overlap by approximately 2,600 graphs in the middle, with Běidūn 14802 preserving the head-portion and Běidūn 07879 the tail-portion. Combined, they reconstruct nearly the entire text — over 10,000 graphs — and confirm the title as Fóxìngguān xiūshàn fǎ 佛性觀修善法 (filling in the lost two-graph head of the tail-cartouche of Běidūn 07879).

The text is unrecorded in any historical Buddhist catalog and absent from all canonical editions. Yè Lùhuá 業露華 had already published a transcript of Běidūn 14802 in Zàngwài fójiào wénxiàn vol. 4 (under KR6v0052 in modified form). The present edition by Nishimoto Teruma 西本照真 prints Běidūn 07879 with collation against Běidūn 14802 and the Yè transcript — completing the reconstruction. The composition window is bracketed by Xìnxíng’s emergence as Sānjiē founder (ca. 580) and his death in 594.

Other points of interest

With this reconstruction, Fóxìngguān xiūshàn fǎ becomes the largest extant Xìnxíng-attributed Sānjiē text — substantially larger than either Dàshèng wújìnzàng fǎ or Fóxìng wèndá. Together these three constitute the surviving documentary base for Sānjiē doctrinal study; outside this trio, the school’s literature is reconstructed from quotations.
