法雲の『法華義記』における「一仏乗」解釈

抄録

This paper is concerned with Fayun's (467-529) interpretation of the title ‘Lotus Sutra’ and the upayakausalya chapter in his Fahua yiji with an examination of his conception of the bodhisattvayana and ekabuddhayana. By comparing this with Zhu Daosheng's (355?-434) interpretation of the Lotus Sutra, the significance of Fayun's interpretation of the Lotus Sutra will be clarified within the wider historical context of Chinese Buddhism. In his Fahua yiji, Fayun compares the ekabuddhayana as described in the Lotus Sutra with the bodhisattvayana as one of the three yanas and affirms the superiority of the ekayana from the viewpoint of causality. Daosheng, on the other hand, adopts as the ultimate aim the standpoint of emptiness-cum-non-grasping without adherence to the ekayana, despite acknowledging the importance of the ekayana doctrine in the the Lotus Sutra. Due to the greater concentration upon Prajñaparamita Sutra material, the notion of emptiness was more of a focal point during Daosheng's time, whereas the relation between the ekayana and the three yanas remained only a secondary concern. On the other hand, it will be argued that it was not until the time of Fayun that the relation between the ekayana, as recounted in the Lotus Sutra, and the bodhisattvayana as one of the three yanas first becomes a key issue.
