As a lay Buddhist, Lǐ Hùn contributed the 1294 postface (跋) to Ch’ŏnch’aek’s 天頙 Chán mén bǎo zàng lù KR6q0162, framing the Sŏn–doctrinal controversy of his day with the classical Chán imagery of “the lion biting the person” versus “Hánlú chasing clods” and praising Ch’ŏnch’aek’s apologetic project for its contribution to the future Sŏn cause.
