Southern-Sòng Buddhist monk and Vinaya editor; lifedates not preserved (DILA A001543). Disciple-successor (in the lineage rather than necessarily a personal disciple, since Yuánzhào died in 1116) of Língzhī Yuánzhào 靈芝元照 (元照, 1048–1116) at Língzhīsì 靈芝寺 in Hángzhōu. His one surviving work is the editorial compilation Zhīyuán yíbiān 芝園遺編 (KR6k0216, X1104), the three-fascicle gathering of Yuánzhào’s miscellaneous writings (jiètǐ 戒體 treatises, lecture pieces for major patrons including Ŭich’ŏn 義天 of Goryeo, the founding-inscription for the Kāiyuánsì ordination-platform at Míngzhōu, etc.). Distinct from the homonymous Dìngguāng Dàoxún 定光道詢 (DILA A014705).
