Heze Shenhui

Heze Shenhui was a student of the Sixth Patriarch Huineng who played a decisive political role in establishing the supremacy of the Southern School of Chan over the Northern School of Shenxiu. At the great debate of Huatai in 732, Shenhui publicly argued that Huineng, not Shenxiu, was the true Sixth Patriarch, and that sudden awakening, not gradual cultivation, represented the authentic teaching. His arguments ultimately prevailed, reshaping the institutional landscape of Tang dynasty Buddhism.

Despite his enormous influence on the shape of Chan orthodoxy, Shenhui's own lineage did not endure beyond a few generations. Later Chan historians, particularly those of the Linji school, tended to downplay his contribution, viewing him more as a political figure than a realized master. Modern scholarship has recovered his significance through the discovery of Dunhuang manuscripts containing his teachings, which reveal a subtle and sophisticated understanding of the relationship between knowledge, practice, and awakening.
