吉蔵『仁王経疏』について -釈二諦品・「三種仏性説」を中心に-

抄録

Jizang (吉蔵), in his Renwang bore jingshu (『仁王般若経疏』), proposed a new theory about Buddhadhatu (仏性) which asserted the three kinds of Buddhatva, i. e. xianchang-foxing (現常仏性), dangchang-foxing (当常仏性), and liaoyin-foxing (了因仏性). His aim seems to combine the idea of Prajña (般若) with Buddhadhatu. The source of his new theory, I suppose, can be found in the Foxing lun (『仏性論』) and She dacheng lunshi (『摂大乗論釈』) of Zhendi (Paramartha 真諦), as well as the Shizihou pusa pin 師子吼菩薩品, a chapter of the Mahaparinirvana-sutra (『浬槃経』).
