Surviving work: the Tiānzhēn Dúfēng Shàn chánshī yào yǔ 天真毒峰善禪師要語 KR6q0194, compiled by Wùshēn. Běnshàn’s teaching-position distinguishes itself by its programmatic emphasis on pre-Bǎizhàng ascetic-discipline (tóutuó 頭陀, dhūta) practices, in contrast to the institutionalised-monastery Chán of his day.
