초기 유가행파의 존재론의 형태와 그 의의 : 삼성과 이제의 관계를 중심으로

Abstract

This paper purports to probe into the structure of the ontology of the early Yogācāra-vijñānavāda and its significance in the history of the development of Buddhist doctrines with special reference to the relationship between the three natures and the two truths. It especially focuses on the understanding of the doctrinal and structural relation between the 'vastu' in the chapter of the Tattvārtha in the Bodhisattva-bhūmi and the 'abhūtaparikalpa' in the Madhyāntavibhāga. For these concepts are understood to have served as the prototypes of the theory of the three natures prior to the doctrinal systematization of the notion of vijñapti-mātra. This study is based upon the hermeneutical ground of the Tridharmacakra advanced at the end of the chapter of the niḥsvabhāvalakṣaṇa in the Saṃdhinirmocanasūtra and the hermeneutical stance of Vasubandhu put forward in the explanation of the theory of the two truths of the Yogācāra-vijñānavāda in his Vyākhyāyukti. In fact, important clues for grasping the ontology of the Yogācāra-vijñānavāda can be found in the descriptions of hermeneutical points concerning the theory of the two truths advanced in the Abhidharmakośabhāṣya, the Vyākhyāyukti, the Tattvārtha, etc. Especially, the Yogācāra-vijñānavāda's interpretation of some passages of the Bhavasaṃkrāntisūtra cited in the chapter of the Tattvārtha suggests a structural parallel between the theory of the three natures and the theory of the two truths. Accordingly, the study on the structure of the ontology of the early Yogācāra-vijñānavāda, with special reference to the relationship between the three natures and the two truths, might contribute considerably to the comprehension of the doctrinal systematization of the thought of the Yogācāra-vijñānavāda, including the philosophical and practical significance of the theory of the three natures as one of the three representative theories of this school.
