Gregory (religion and East Asian studies, Smith College) examines the life and work of Kuei-feng Twung-mi (780-841), traditionally honored as the fifth patriarch in both the Hua-yen scholastic tradition and the Ho-tse line of southern Ch'an. He describes doctrinal classification, the ground of practice, and the broader intellectual tradition. Parts of his study have been published as separate articles. Annotation c.
