Wúzhù 無住
Táng-dynasty Chán master, founder of the Sìchuān Bǎotáng 保唐 school. Dharma heir of Wúxiàng 無相 (684–762, the Korean monk known in Korean as Musang and as Jìngzhòngsì Kim héshang 淨眾寺金和尚). In lineage terms, Wúzhù’s line descends through Wúxiàng, Chǔjí 處寂 (665–732), Zhìshēn 智詵 (609–702), and claims unbroken continuity back to the Sixth Patriarch Huìnéng 慧能.
The Bǎotáng school is best known for its radical interpretation of “no-thought” (wúniàn 無念) and its rejection of conventional monastic-ritual forms. Wúzhù’s teaching is preserved primarily through the Lìdài fǎbǎo jì 曆代法寶記 (KR6q0001), compiled by his disciples in the years immediately after his death and organised around the Bǎotáng claim to be the true heirs of the Bodhidharma transmission. The Bǎotáng school itself did not survive long past the late Táng; Wúzhù is a key figure in the eighth-century Sìchuān Chán milieu and an important — though combative — voice in the wider Chán-lineage debates of the period.
