The book A Brief Lecture on the Headstream of the Chinese Buddhism written by Lyu Cheng is a modern masterpiece of Chinese Buddhism. It contains the two parts-"Hsien-shou School" and "Hua-yen School"-concerning the discussions on Hua-yen Thought specifically. I consider that there are some problems in approximately 30 comments about Lyu Cheng’s Hua-yen Thought, such as the sources and ratings of Five Teachings, Fa-tsang Ten School and Kuei-chi Eight School, Huei-kuang Three Teachings, Instant Teaching and the Method of Teaching, Instant Teaching and Chan School, Pan-chiao and Gotra, the Mind of True Suchness and Water and Wave in Mahyna raddhotpda stra, insentient things having the Buddha nature, Avatasaka stra and Complete Teaching, the same body and the different bodies, mutual identity and interpenetration, Chih-yen and Fa-tsang, She-lun School and Wei-sci School, and gate seeing mutually. This paper is to give comments and discussions on the places like these.
