『법화현의』권1 「회이(會異)」에 대한 비판적 검토 －『유마경현소』 권1 「대사실단(對四悉檀)」과의 비교를 중심으로

Abstract

The “Huiyi” (會異) section in Volume 1 of Fahua xuanyi (法華玄義) and the “Duisixitan”(對四悉檀) section in Volume 1 of Weimojing xuanshu (維摩經玄疏) both explore the alignment of the Four Siddhāntas (四悉檀) with the Five Categories of Profound Meaning (五重玄義) to establish Zhiyi’s (智顗, 538-597) doctrinal system. These two sections demonstrate significant interrelations, which are believed to have been influenced by the lost text Si xitan yi (四悉檀義) from Zhiyi’s commentary on the Vimalakīrti Sūtra. Despite the existence of notable similarities between the sections, there are also significant differences in content and scope. This paper addresses these issues through a comparative and analytical study of both texts. An in-depth comparison of the overall structure and content of Fahuaxuanyi and Weimojingxuanshu reveals three main types of variation: (1) differences between the content of the Lotus Sūtra and the Vimalakīrti Sūtra, (2) the influence of Sixitanyi, and (3) discrepancies related to the respective audiences of the texts. Specifically, the variations in “Huiyi” likely resulted from Guanding’s (灌頂, 561-632) editorial revisions based on Zhiyi’s teachings. Additionally, while Fahua xuanyi and Weimojing xuanshu are both dated to the Sui Dynasty, the “Huiyi” section reveals terminological changes that reflect a later era. This suggests that the extant version of Fahua xuanyi was revised after the Tang Dynasty, and this revision is attributed to Guanding’s editorial work. The study also challenges previous claims that Guanding intervened in Weimojing xuanshu and proposes instead that Guanding integrated content from Si xitan yi or Weimojing xuanshu into his personal interpretations. Furthermore, this paper identifies instances where content unique to Fahua xuanyi refers to Guanding’s personal interpretations, demonstrating his deep involvement in the composition of Fahua xuanyi.
