攝山系 三論師의 定慧雙修說과 天台師의 敎觀兼修說 比較

Abstract

The purpose of this paper is to examine the feature, similarity and difference of their thought between Jeonghye Ssangsu theory(the theory of simultaneous cultivation of Samadhi and Prajna) and Gyogwangyeomsu theory(the theory of harmonious cultivation of Zen and Doctrine) and their inter-exchange in the Buddhist history of Weijinnanbeichao Period. The two theory is an important theory that Samron masters and T'ientai masters asserted respectively. They have a inter deep relation both in the similarity of Jeonghye(samadhi and prajna) thought and in their thought background. Then,T'ientai's Gyogwangyeomsu theory derives from Jeonghye Ssangsu theory of Samron masters. In particular, Seungrang founded Samron master's Jeonghye Ssangsu theory. If Jizang's assertion is relevant,then it is certain that Seungrang established the thought system of "Jeonghye is One", based on Samron. Actually, these two thought systems have many overlapped factors in region, period, and thought, so which forms the source of similarity between these two thoughts. However, an eminent relgious master such as T'ientai embraced both doctrine and zen schools widely and then unified them including Jeonghye Ssangsu theory. While the roots of Samron masters' thought were Samron or Heart Sutra and Treatise on the Great Perfection of Wisdom,T'ientai masters tried to cover all Gyopan(doctrine school) and to set up a practical zen system chiefly on the Lotus Sutra. The thought of "Jeonghye is One" made T'ientai complete unification philosophy, 'the unification of doctrine tenet and zen tenet,' which is the marrow of Gyogwangyeomsu theory. In brief, if Samron masters' Jeonghye Ssangsu theory were a starting and triggering point, then Gyogwangyeomsu theory would be a arriving point and a completed stage as well. However, in that any thought cannot ignore a social and cultural background, the unification philosophy of T'ientai can be referred as the completion of Jeonghye Ssangsu theory.
