Zizhou Zhishen

Zhishen (智詵, 609–702) is named in the *Lìdài Fǎbǎo Jì* and other early Sichuan Chan documents as a direct disciple of the Fifth Patriarch Hongren who, on leaving Mount Huangmei, settled at Dechun Temple in Zizhou (modern Sichuan) and transplanted East Mountain teaching to the southwest^[1]. He thus stands at the head of the line of teachers — Zhishen → Chuji → Wuxiang → Wuzhu / Shenhui — that twentieth-century scholarship has called the "Sichuan school" or the Bao-Tang / Jingzhong stream of early Chan^[2].

Modern reconstructions, drawing on the Dunhuang manuscripts recovered in the early 1900s, treat Zhishen as a historically important figure who anchored a regional lineage of Chan distinct from the later northern (Shenxiu) and southern (Huineng) orthodoxies eventually canonised in the *Platform Sūtra*^[3]. The doctrinal content of his teaching is poorly preserved, but his presence in the Hongren-disciple lists in both the *Léngqié Shīzī Jì* and the *Lìdài Fǎbǎo Jì* shows that Sichuan was an active early Chan centre well before the rise of the classical Tang houses.
