The Zifang yiwang ji 自防遺忘集 has been studied by means of the sentences quoted under this title in a commentary on Fazang’s Huayan wujiao zhang 華厳五教章 compiled by a Japanese monk, and the Huayanjing yichao 華厳経義鈔 in 10 fascicles, which is considered the only extant source. However, there are two problems. One is the supposition that the Huayanjing yichao is the Zifang yiwang ji on the basis of a colophon of the former, which was written in later times. Another problem concerns the existence of Wenchao’s 文超 Guan jian 関鍵 based on a portion missing from the Huayanjing yichao.
Examining their sentence structures, I confirm that the Huayanjing yichao is the Zifang yiwang ji. And I report the discovery of the page of chapter 8 missing from the Huayanjing yichao, which is relevant for the question of the existence of the Guan jian.
