Jīngāng jīng lüètán 金剛經略談
Brief Discussion of the Diamond Sūtra by 觀衡 Guānhéng (撰)
About the work
A short one-juan discussion-essay on the Vajracchedikā Prajñāpāramitā-sūtra by Zhuānyú Guānhéng 顓愚觀衡 (1579–1646; sobriquets Sǎnjū 傘居 “Umbrella-Dwelling,” Yúnjū 雲居), late-Míng / early-Qīng monk in the Yúnjū lineage. The format is lüètán — discursive essay, not verse-by-verse commentary — and the text moves directly to the doctrinal heart: the title is parsed (金剛 as figure, 般若 as dharma; jīngāng signifies the cutting-off-and-emptying power of prajñā rather than the unbreakability of vajra-as-substance), the relation of the contemplation-prajñā (觀照) to the reality-prajñā (實相) is laid out, and the sūtra is read as a unified instrument for bùqǔ 不取 (“not-grasping”) — the abolition of attachment to any of the xīn / fó / zhòngshēng triad. Preserved as X25 no. 481. notBefore / notAfter = Guānhéng’s active period (1610 / 1646 — death year).
Abstract
The opening passage offers a reconfigured reading of the title-character jīngāng: rather than relying on the standard “vajra is hard, sharp, cuts everything” gloss (the gem-substance figure), Guānhéng emphasizes that the sūtra belongs in the Mahāprajñāpāramitā corpus under the heading néngduàn fēn 能斷分 (“the section on cutting-power”), so the figure’s operative meaning is cutting and emptying — the diamond’s function, not its substance. The essay then traces how the sūtra’s negations (心佛眾生無性, 本寂; “mind, Buddha, sentient beings have no self-nature, are originally quiescent”) work as an instrument: the practitioner’s bùqǔ (not-grasping) discloses, rather than constructs, the běnlái miànmù 本來面目 (“original face”). A brief but pointed cross-reference is made to the Śūraṅgama-sūtra’s jīngāng-wáng bǎojué rúhuàn sānmótí 金剛王寶覺如幻三摩提 — establishing that jīngāng in Mahāyāna scripture is consistently the figure for cutting-emptying power, not for unbreakable substance. The essay form is brisk, oral-feeling, and shorter than most works in this section — fitting Guānhéng’s reputation for zhuānyú (“simple-minded foolishness”) plain teaching.

Other points of interest
Guānhéng’s reading shifts the operative meaning of jīngāng from substance-figure (the Indian vajra gem) to function-figure (the néngduàn cutting-power) — a small but consequential hermeneutic move that re-aligns the Vajracchedikā’s figural register with its doctrinal operation. This reading is followed implicitly by Hānshān Déqīng (KR6c0062) and explicitly by Zhìxù (KR6c0067), placing Guānhéng in the same exegetical wave that re-grounded Vajracchedikā commentary in the late Míng.
