Jīngāng jīng yǐng shuō 金剛經郢說
The Diamond Sūtra: A Discourse from Yǐng by 徐發 Xú Fā (詮次)
About the work
A one-juan early-Qīng (Kāngxī-era) Vajracchedikā discourse by Xú Fā (sobriquet Nánhú Pǔrén 南湖圃人), Jiāxīng layman who combined Buddhist exegesis with mathematical-calendrical scholarship. The title’s yǐngshuō 郢說 (“Yǐng discourse”) alludes to the Zhuāngzǐ “Wàiwù” parable of Yǐngrén yùn jīn chéng fēng 郢人運斤成風 (“the Yǐng man wielding the axe in the wind”) — Yǐng signaling skilled, intuitive expounding, and shuō signaling discursive rather than verse-by-verse format. Composed in Kāngxī 12 = 1673 per the preface dated Kāngxī shíyǒu èr nián guǐchǒu zhòngdōng nánzhì zhī qīrì 康熈十有二年歲在癸丑仲冬南至之七日 (winter-solstice + 7 days). The catalog credit-line quáncì 詮次 (“explained-and-arranged”) indicates Xú’s work is a topical / topical-sequence exposition rather than a strict line-commentary. Preserved as X25 no. 488. notBefore / notAfter = 1673. Catalog dynasty 清.
Abstract
The self-preface (No. 488-A) opens with a striking cosmo-ontological framing in the Yìzhuàn / Tàijí register: lǐ gēn yú xìng, xìng bì yǒu suǒ shòu zhī tú; xíng qū yú mìng, mìng bì yǒu shōu zào zhī fǔ 理根於性，性必有所受之途；形區於命，命必有收造之府 (“Principle is rooted in nature, and nature must have a path on which it is received; form is divided in life, and life must have a treasury for what it gathers and creates”). The discourse then frames the Vajracchedikā through the zì yǒu rù wú, zì wú ér rù wúwú 自有入無，自無而入無無 (“from being-into-nothingness, from nothingness into nothingness-of-nothingness”) progression — explicitly aligning the sūtra with the Tàijí / Wújí dialectic of late-Sòng Lǐxué (Zhū Xī’s Tàijí tú shuō and after). The body of the discourse is a topical exposition organized by Xú’s signature themes — bùzhù 不住 (non-abiding) read as bùfā zhī zhōng / yǐfā zhī hé (the unmanifest mean / the manifest harmony of the Zhōngyōng), and the sūtra’s negations folded into a Confucian-Buddhist syncretic register typical of Kāngxī-era Jiāxīng lay scholarship.
Translations and research
No substantial dedicated secondary literature located on Xú Fā’s Buddhist work; for context on his calendrical-mathematical writing see modern studies of early-Qīng Jiāxīng intellectual life.
Other points of interest
The combination — Vajracchedikā commentary + Tàijí cosmology + tiānyuán algebraic computation in the same author — is characteristic of the early-Qīng kǎozhèng-tinged Jiāngnán lay scholarly milieu in which Buddhist devotion, Sòng-Míng xìnglǐ metaphysics, and post-Jesuit mathematics coexisted as partial responses to the dynastic-transition intellectual crisis. Xú’s Yǐngshuō is one of the more philosophically ambitious lay Vajracchedikā commentaries of the period.
