Late-Yuán / early-Míng Chan monk and imperial Buddhist administrator, principal Buddhist confidant of the Hóngwǔ 洪武 emperor Zhū Yuánzhāng 朱元璋 (r. 1368–1398). Sobriquets Jìtán 季潭 and Quánshì 全室. Born Yánjù 5 (= 1318, seventh month, seventeenth day) under the Yuán Rénzōng era; died Hóngwǔ 23 (1390). Successively abbot of Jìngshān 徑山 and Tiānjiè 天界 monasteries — the latter the leading Buddhist institution of Hóngwǔ’s new dynastic capital at Nánjīng — hence his common designations 徑山宗泐 and 天界宗泐.
Hóngwǔ relied on him for the early-Míng reorganisation of the Buddhist saṅgha and for the production of state-sponsored Buddhist texts. With his collaborator 如玘 (1320–1385), he edited the Bōrě bōluómìduō xīn jīng zhùjiě 般若波羅蜜多心經註解 (T1714 = KR6c0141), the Jīngāng bōrě bōluómì jīng zhùjiě 金剛般若波羅蜜經註解, and the Léngqié ābáduóluó bǎojīng zhùjiě 楞伽阿跋多羅寶經註解 — the three so-called “imperially-decreed commentaries” of Hóngwǔ 11 (1378), each carrying the emperor’s own preface. He was sent on diplomatic missions to the Western Regions and India in Hóngwǔ 11–14 (1378–1381) to obtain Sanskrit texts.
Doctrinally Línjì-school Chan, but his commentarial output is markedly latitudinarian, drawing on Huáyán, Yogācāra, and Pure Land sources — characteristic of late-Yuán syncretic Chan. His collected literary writings circulate as Quánshì wàijí 全室外集.
