A Buddhist chánshī 禪師 (“meditation master”) associated with Wǔyīn Shānshì sì 五陰山室寺, attested only in the colophon of the apocryphal Fó wèi xīnwáng púsà shuō tóutuó jīng KR6u0022 (T85n2886) as the commentator of that text: “五陰山室寺惠辨禪師註”. The figure is not recorded in the Gāosēng zhuàn literature, the Lìdài fǎbǎo jì, or other standard early-Chán histories; his lifedates and place of activity are not securely known. The temple name and the doctrinal cast of his comments place him plausibly in the late 7th- or 8th-century early Chán milieu of northern China but the identification is provisional. Not to be confused with the much later Sòng-dynasty Chán master 慧辨琦 (Huìbiànqí, fl. 11th century) of the Jìngshān zhì tradition, who is a distinct figure.
