「新義教学の大成者」たる聖憲について―「四種身」に対する解釈を中心として―=About Shōken, “A Master Scholar of Shingi-Shingon Doctrine”: Focusing on the interpretation of “four kinds of Buddha-Body”
Shōken inherits Raiyu’s Kajishin-setsu and is called “a master Scholar of Shingi-Shingon Doctrine.” One of Shōken’s masterpieces is “Daisyo -daisanjū,” and one of its characteristics is to explain various topics in parallel with the “theory of Jishō-setsu(Kogi-Shingon) is…” and the “theory of Kaji-setsu (Shingi-Shingon) is… .” In this paper, I picked up “four kinds of Buddha-Body” from among them and examined the validity of those two theories. In addition, I considered the reason Shōken is said to be “A Master Scholar of Shingi-Shingon Doctrine.” Results found that Shōken’s “theory of Jishō-setsu” did not agree with the theory of Kogi-Shingon’s scholars, for instance, Dōhan, Gōhō, and Yūkai and that it was not necessarily the theory of Raiyu. Therefore, Shōken as “a master Scholar of Shingi-Shingon Doctrine” is not simply an arrangement of the doctrine of Kogi and Raiyu but is systematized in a way that further clarifies the Shingi-Shingon doctrine’s uniqueness.
