A Northern-Sòng Huáyán 華嚴 scholar and the principal Sòng-period editorial-redactor of the Tang HuáyánChán synthesis tradition, particularly of the corpus of Zōngmì 宗密 (780–841). Lay surname Dōngpíng 東平 — alternate persona-name Chángshuǐ Zǐxuán 長水子璿 (after his Chángshuǐyuàn 長水院 residence). Born 965 CE; died 1038 CE, age 73.
His scholarly career was devoted to reorganizing and editing the great Tang doctrinal-Buddhist commentaries for Sòng-period reading-and-practice — particularly those of Zōngmì, the fifth Huáyán patriarch and the principal Tang HuáyánChán synthesizer. His major editorial works include:
- Jīngāng jīng shūlùn zuǎnyào 金剛經疏論纂要 (KR6c0040–KR6c0041) — Sòng editorial recension of Zōngmì’s Diamond Sūtra commentary.
- Yuánjué jīng dàshū 圓覺經大疏 (T1795) and Yuánjué jīng dàshū chāo 圓覺經大疏鈔 (T1796) — Sòng editorial recensions of Zōngmì’s commentary on the Sūtra of Perfect Enlightenment.
- Various Huá-yán-school sub-commentaries.
His work was foundational for the Sòng-period Huá-yán-school revival and the continued availability of Tang HuáyánChán synthesis literature in Sòng-and-after monastic-pedagogical practice.
