『涅槃経』所説戒聖行の果について

――智顗の教学を中心として――

抄録

How does one reach the first Bodhisattva stage according to the Jie shengxing 戒聖行 (Holy Practice of Discipline) of the Tiantai Biejiao 別教 (Distinct Teaching) scheme? Different opinions are offered in the Sijiaoyi 四教義 of Zhiyi 智顗 (538–597), the Weimo jing xuanshu 維摩経玄疏 of Zhiyi and the same author’s Miaofa lianhua jing xuanyi 妙法蓮華経玄義 (Fahua xuanyi).

In the Southern version of the Nirvana Sutra there are three Holy Practices, Jie shengxing, Ding shengxing 定聖行 (Holy Practices of Meditation), and Hui shengxing (Holy Practices of Wisdom). In the Weimo jing xuanshu it is taught that in order to attain the first Bodhisattva stage in the Biejiao, one must practice the three Holy Practices beginning from the Shixin wei 十信位 (Ten Faiths which form the first portion of the Bodhisattva stages). According to the same text, the Jie shengxing is the tenth stage for the Biejiao Bodhisattva.

In the Fahua xuanyi, one disregards the Ding shengxing and Hui shengxing, only cultivating Discipline and thus goes directly to the First Bodhisattva Stage. In the same manner, in the Sijiaoyi of Zhiyi one attains the First Bodhisattva Stage solely through the Jie shengxing. However, in another place in the same work, agreeing with the Weimo jing xuanshu the text teaches that one must practice all three and not only Discipline.

The problem of these competing schemes is discussed in this paper.
