Shàndǎo 善導 (613–681), one of the Five Patriarchs of Chinese Pure Land Buddhism (Lúshān Huìyuǎn 廬山慧遠 → Tánluán 曇鸞 → Dàochuò 道綽 → Shàndǎo → Hùaigǎn 懷感 → Shǎokāng 少康 → Yánshòu 延壽), and the most consequential figure of the Tang Pure Land tradition. Native of Sìzhōu 泗州 (modern Anhui). Studied under Dàochuò 道綽 (562–645) at the Xuánzhōngsì 玄中寺, then settled in the Cháng’ān region. He is reported in Pure Land hagiography to have written 100,000 copies of the Amitābha Sūtra and to have painted 300+ Pure Land paintings; he is one of the principal Tang figures of explicit Pure Land devotional practice. His [[KR6f0076|Guān wú liàng shòu fó jīng shū 觀無量壽佛經疏]] (T1753, the Four-Fascicle Pure Land Commentary) became the foundational doctrinal text of Hōnen’s and Shinran’s Japanese Pure Land schools.
