良栄理本における自受用身の扱いについて――『群疑論』所説の「覚照性」に着目して――

抄録

This paper concerns Ryōei Rihon’s良栄理本 （1346-1428）understanding of juezhaoxing覚照性 in the seventh century Shi Jingtu qunyi lun 釈浄土群疑論 of Huaigan 懐感. Heretofore, it has been understood that the wisdom of the self-enjoyment body自受用身 recognizes the truth 理 of the Dharma body. However, adding to this previous interpretation, Ryōei established the interpretation that juezhao覚照 is the work of wisdom connected with the Dharma body. The main point of these two interpretations concerns the difference between the Dharma body and the self-enjoyment body. That is, if the former interpretation is adopted, the Dharma body and the self-enjoyment body are distinguished. In contrast, if the latter is adopted, the two bodies are the same.

Therefore, the fact that Ryōei uses these two exegeses together suggests that he is using the difference between the Dharma body and the self-enjoyment body in different ways.
