Jīngāng jīng zhùjiě tiězǎnxián 金剛經註解鐵鋑錎
The Iron-Borer Annotated Diamond Sūtra by 屠垠 Tú Yín (註)
About the work
A two-juan late-Míng / early-Qīng vernacular Vajracchedikā commentary by the layman Tú Yín (sobriquet Qīngxū jūshì 清虗居士). The catchy title, tiězǎnxián 鐵鋑錎 (“iron-borer,” literally “iron-chisel-and-mount”), is glossed by the author himself in the opening verse: each of the thirty-two sections of the Liáng Zhāomíng division of the sūtra is to be treated as one of “thirty-two iron borers” (三十二個鐵鋑錎) — only the practitioner who can “chew through” them all (jiáopò 嚼破) deserves the title shànzhīshì 善知識 (good spiritual friend, kalyāṇa-mitra). Each section is then cast in a four-line seven-character verse summary followed by a vernacular prose annotation of broadly Chán-Pure-Land character. Preserved in Xùzàngjīng X24 no. 470. notBefore tentatively set to 1573 (a conservative terminus post quem — Wànlì-era lay-Buddhist commentary boom under which Tú is most plausibly active); notAfter = 1648 (the dated Shùnzhì wùzǐ publishing preface of Gōng Tài).
Abstract
Note on author’s name. The catalog meta gives the author as 屠根; the source text consistently writes 屠垠 (with 垠 yín “edge / shore”), as does DILA authority A001036 (note: DILA’s title-rendering uses 鐵鋑䤾 but the X24 source has 鐵鋑錎). The form 屠垠 is followed here.
Author and milieu. Beyond the sobriquet Qīngxū jūshì the author is otherwise unknown. The text was held in manuscript by two Sūzhōu literati (Xià, Lín èrjūn 夏林二君) who showed it to 龔泰 Gōng Tài (sobriquet Yīzhǐ jūshì 一止居士 of Kēshān 柯山, secondary name 瑞麟生父 Ruìlín shēngfù) when Gōng was visiting Sūzhōu in the winter of dīnghài 1647. Gōng — at the time 75 suì — found the manuscript so apt to his own newly-deepened devotional practice (the autobiographical preface narrates losing his father in childhood, a long career of trade in Tiānjīn, encounter with a míngshī 明師 who taught him the discipline of fasting and precepts as a bàomǔ “repaying mother” practice, and decision to publish the manuscript as merit-making) that he funded the printing. The publishing colophon is dated 順治戊子端月朔日 = 1648 first-month first-day (Shùnzhì 5/1/1, Western calendar 1648-01-25). The printing thus marks an early-Qīng (Manchu-conquest era) lay-Buddhist devotional act, recovering a Míng-period manuscript.
Form. Each section (分) of the sūtra is presented in three layers: (a) a four-line seven-character verse epitome (jiē 偈) of the section, framed in the manner of a popular bǎojuàn 寶卷 chapter-couplet; (b) the sūtra text proper; (c) a prose annotation in vernacular-leaning literary Chinese. The doctrinal idiom is broadly Chán with Pure-Land cadences: the recurring contrast is between zhèngniàn 正念 (right-mindfulness) and kōng guò chūnqiū 空過春秋 (“frittering away the seasons”), aimed at “those who recite this sūtra daily but only count their tally of recitations” (i.e., a critique of mechanical recitation in favor of inwardness).

Other points of interest
The work is a noteworthy specimen of late-Míng / early-Qīng bǎojuàn-influenced vernacular Buddhist commentary, a genre in which scholastic Sanskrit-derived terminology yields to four-syllable rhythmic prose and seven-syllable rhymed verse aimed at oral performance and lay reading. The chapter-by-chapter verse-prose-annotation triptych anticipates the format of late-Míng bǎojuàn and Qīng-period lay devotional editions. The publishing context (Manchu-conquest year 1648, Sūzhōu literati, autobiographical filial-piety preface) is itself a small social-history document of how Buddhist printing functioned as a survival strategy and merit-making program for Jiāngnán literati in the dynastic transition.
