What is "shenhui"

Heze Shenhui (Chinese:菏泽神會/神会; Wade–Giles: Shen-hui; Japanese: Kataku Jinne, 684-758) was a Chinese Buddhist monk of the so-called "Southern School" of Zen and the dharma heir of Huineng.

Shenhui is notable for his strident attacks on Yuquan Shenxiu and the associated "Northern School", which was the most prominent branch of Chan Buddhism in China at the time. He accused them of propagating gradual teachings, as opposed to his own sudden teachings.

Shenhui's own lineage, called the Heze lineage , probably died out around the time of the Great Anti-Buddhist Persecution in 845, with Guifeng Zongmi being the only notable monk in the lineage.
