Guifeng Zongmi

Guifeng Zongmi (Chinese: 圭峰宗密; pinyin: Guīfēng Zōngmì; Japanese pronunciation: Keihō Shūmitsu) (780–1 February 841) was a Tang dynasty Buddhist scholar and bhikkhu, installed as fifth patriarch of the Huayan school as well as a patriarch of the Heze school of Southern Chan Buddhism. He wrote a number of works on the contemporary situation of Tang Buddhism, which also discussed Taoism and Confucianism. He also wrote critical analyses of Chan and Huayan, as well as numerous scriptural exegeses.

Zongmi was deeply interested in both the practical and doctrinal aspects of Buddhism. He was especially concerned about harmonizing the views of those that tended toward exclusivity in either direction. He provided doctrinal classifications of Buddhist and non-Buddhist teachings, accounting for the apparent disparities in doctrines by categorizing them according to their specific aims.
