Déyīn 德因
Late-Sòng–Yuán transitional Buddhist ritual master. Referred to in the compilation as Gāofēng Yīnshī 高峰因師 (“Master Yīn of Gāofēng”); self-designation Yěshì bǐqiū Déyīn 野釋比丘德因 (“Wild Buddhist Bhikkhu Déyīn”). Not to be confused with the earlier Southern-Sòng LínjìYángqí master 雪峯大夢德因 Xuěfēng Dàmèng Déyīn (DILA A009564), who is a distinct person.
Lifedates approximate: born in a bǐngshēn 丙申 year, per his juan-15 autobiographical declaration in KR6q0165; this places his birth in 1236 (consistent with the compilation’s Zhìyuán 24 = 1287 preface date and the narrator’s statement that he has attained “four decades” of age at the time of the self-narrative’s composition). Death year unrecorded. Native place not explicitly given; his self-narrative describes wandering the southern Chinese Chán circuit (Héngpǔ 橫浦, Língjiāng 凌江, Qūjiāng 曲江, Wēngyuán 翁源).
Father died when he was ten; his mother remarried five years later, leaving him orphaned. Took ordination in his youth. After years of wandering, discovered the ruined Lóngquányuàn 龍泉院 on Gāofēng 高峰, secured imperial patronage and rebuilt it — restoring the dharma-hall, constructing new sleeping-quarters, gatehouse, and corridors, installing 73 Buddha-statues and 84 painted saints, and acquiring over 600 units of tax-land as permanent endowment. Concurrently held abbacies at Liánhuāyuàn 蓮花眾福 (via prefectural appointment).
His one surviving work is the Gāofēng lóngquán yuàn Yīn shī jí xián yǔlù KR6q0165 in 15 juan, compiled by his junior-disciple Rú Yīng 如瑛 — a comprehensive compendium of Yuán-period Chinese Buddhist ritual language for calendrical, life-cycle, and supplicatory occasions. The work is a rare witness to the practical liturgical life of late-Sòng / Yuán popular Buddhism, and uniquely preserves his juan-15 first-person prose autobiography.
