lTa ba'i khyad par における「経 (部) 中観」の意味

抄録

Despite a number of studies so far conducted on the formation and reality of the so-called Sautrankika as well as on the history of the Madhyamika school, there still remains an important yet unsolved question. That is, what Ye shes sde means by his usage of both mdo sde (pa'i, spyod pa'i) dbu ma and rnal 'byor spyod pa'i dbu ma in his doxographical work titled lTa ba'i khyad par (TKh). It was Prof. Sh. Matsumoto who first critically discussed the above topic and drew the following two conclusions: (1) The above two appellations used in TKh refer not to the sub-schools of the Madhyamika but to respectively Bha (va) viveka's Prajñapradipa & Madhyamakahrdaya and Santaraksita's Madhyamakalankara. (2) In TKh, mDo sde (経) of mDo sde (pa'i, spyod pa'i) dbu ma means not the Sautrantika school but sutras such as Prajñaparamitasutra and others, while rNal 'byor spyod pa (瑜伽行) of rNal'byor spyod pa'i dbu ma refers not to the Yogacara school but to the treatise Yogacarabhumi.
The present paper deals with whether the above two interpretations given by Prof. Matsumoto are tenable or not by analyzing his grounds for discussion. The conclusion of this paper is the following: While the first point is rightly documented, the second, rather revolutionary one has unfortunately no good grounds.
