Taehyun 太賢 commented on the Fanwang-jing 梵網経 in his Pommanggyong kojokki 梵網経古迹記,and saw it as the One Vehicle teaching 一乗教.He accepted the trividhāni śīlāni and included the Precepts for the seven groups of disciples 七衆戒 and the Yogācāra precepts in the precepts of the Fanwang-jing 梵網戒.In addition, he cited the Yogācāra precepts as a basis for the non-transgression 無違犯 of Bodhisattvas.
Taehyun is the founder of the Silla Yogācāra School, and it is natural that he quotes Yogācāra precepts. However, he did not comment on the Yogācāra precepts as did Seungjang 勝荘,but cited the Yogācāra precepts as the basis of his commentary.
In this study I confirm the characteristics of quotations from the trividhāni śīlāni and Yogācāra precepts in Taehyun’s Pommanggyong kojokki. And I examine how it had an influential relation with commentaries later tham Zhiyi 智顗.I further confirm the location of Taehyun in the history of commentaries on the Fanwang-jing.
