Pramāṇasamuccayaṭīkā 第1 章に見る Ṣaṣṭitantra 注釈書の知覚論 : Yuktidīpikā との関連を中心に

Abstract

Vārṣagaṇya's Ṣaṣṭitantra ( ṢT ) is no longer extant, and its fragments are available only from the literature of other schools. One of the most important reconstructions of the ṢT is that of its theory of perception, which is found in the first chapter of Jinendrabuddhi’s Pramāṇasamuccayaṭīkā ( PSṬ ) a commentary on the Pramāṇasamuccayavṛtti of the Dignāga (480–540). In this paper, I will discuss the three commentaries, Ṣaṣṭitantravṛtti ( ṢTV ) (ṢTVa, ṢTVb and ṢTVc), from the perspective of the definition of perception in the ṢT. I will also discuss their relation to the Yuktidīpikā (ca. 680–720, YD), a commentary on the Sāṃkhyakārikā( SK ). The ṢT characterizes perception as the function of the sense faculties (indriya) that are controlled ( adhiṣṭhita ) by the mind (manas). Therefore, I particularly examine the function of the mind and sense faculties in the ṢTV and the YD.//The ṢTVb regards perception as the instrument of valid cognition ( pramāṇa ) that requires sentience (caitanya) of the Spirit (puruṣa). Perception arises with the mind providing sentience for the operation of the sense faculties through the mind. Similarly, the YD discusses the Spirit in relation to the pramāṇa theory and considers that the sense faculties,when they are provided with sentience through the 'adhiṣṭhita' of the mind, begin to grasp objects. Furthermore, the ṢTVa and ṢTVb consider that sense faculties, in grasping objects, transform into the form of those objects. YD also holds that view. Since the SK defines perception as the function of intellect ( buddhi ), it is natural that the ṢT and the YD have different views on perception. However, their points of agreement are noteworthy.// Thus, the YD shares common features with the ṢTV, especially ṢTVb. In addition, we have found text in the YD that might have been quoted directly from the ṢT. Consequently, it is necessary to take into account its relation to the YD, which holds similar views to the ṢT and ṢTV, in order to reconstruct the perception theory of the ṢT and to reaffirm anew the importance of the study of the YD
