Sòng-dynasty Chán monk, abbot of the Bǎifúyuàn 百福院 in Lóngxīngfǔ 隆興府 (modern Nánchāng, Jiāngxī; the prefecture was created under that name in 1163, fixing a terminus post quem for the author’s activity). Lifedates not preserved (DILA “生平不詳”). His sole surviving work is the Xiāoshì Jīngāng kēyí 銷釋金剛經科儀 — a liturgical-recitation outline of the Vajracchedikā in the seven-fold kēyí format (提綱, 要旨, 長行, 結類, 頌經文, 警世, 結歸淨土). The work circulated independently as a Pure-Land-tinged Chán performance text and is preserved both as ZW0053 (the bare kēyí) and as the substrate of the much larger Míng-period annotated compendium KR6c0055 Xiāoshì Jīngāng jīng kēyí huìyào zhùjiě (X24 no. 467) of 覺連.
Not to be confused with the more famous Yǒngmíng Yánshòu 永明延壽 (904–975), author of the Zōngjìnglù 宗鏡錄 — that is a work title, not a personal name; nor with the Japanese Sōtō Sōkyō 大圓宗鏡 (DILA A036656) or the Republican-era 性法宗鏡 (1898–?, A046524).
