반야중관경론과 연화계(蓮華戒)의 주석에 따른 『반야심경』 이해 및 중관학파의 수행 오도와 ‘즉’의 의미

Abstract

Looking at the current status of domestic and international research on the Prajñāpāramitā-hṛdaya-sūtram, most of them are based on the Yogācāra thought or the Buddha-nature thought, and there are not many that are based on the Madhyamaka thought. The reason for this is that Xuanzang (玄奘, 602-664), said to be the first translator of the Prajñāpāramitā-hṛdaya-sūtram, and his disciples were all monks of the Yogācāra thought lineage, and the center of East Asian Buddhism was the Buddha-nature thought. However, I believe that in order to understand the original intent of the Prajñāpāramitā-hṛdaya-sūtram, research based on the Madhyamaka thought is also necessary. This is because it was not the Yogācāra thought or the Buddha- nature thought but the Madhyamaka thought that orthodoxly inherited the emptiness thought of the Prajñāpāramitā-sūtra while considering the Prajñāpāramitā- sūtra as a sutra of clear teaching. Therefore, in this study, I divides the Prajñāpāramitā-hṛdaya-sūtram into several parts according to the ‘Five Paths of Practice’ mentioned by Kamalasila, a scholar of the later Madhyamaka school, and attempts to understand each part based on the Prajñāpāramitā-Madhyamaka literature and related previous studies. And then, based on that understanding, I tried to define the ‘Five Paths of Practice’ of the Madhyamaka school, and along with that, I tried to figure out the meaning of ‘卽’ found in ‘色卽是空 空卽是色’.
