Jhaveri by her friends and well-wishers. As lias been stated by the author, few scholars have utilized the Samkhya-yoga sources and the ideas contained in them to formulate a systematic Samkhya-Yoa theory of Pariņāma, and the Jain sources to formulate the Jain theory of Parināma, and the Jain sources to formulate the Jain theory of Parinama. Although the problem of relation between the Särikhya-Yoga and the Jain systems has been touched by scholrs like Grabe, Jacobi, and others, 110 one has attempted a comparative study of these systems and their bearing on the theory of Parinama. The Thesis has been divided in ten chapters: (!) Seeds of Parināma in the earliest Sanskrit literature (250 B.C. - 200 B.C.); (2) Sankhya Ideas in pre-Isvarakrsna literature; (3) Parinama in the Samkhya-Kārika and its commentaries; (4) Development of Pariņāma in the Yoga-sütras and their important commentaries, as also in the Säinklya-sūtras and their commentaries; (5) Other topics relted to Parināma; (6) Jain sources; (7) Pariņāmavāda in thie Agamas; (8) Parināma in the works of Umāsväti and Kundakuunda; (9) Parinama in the Tarka period; and (Sātkhya-Yoga and Jain - a comparision. There is further an appendix on 'Agurulaglıy', followed by the Bibliograplıy listing 72 Sanskrit and Prakrit works, 45 works in English, and 11 Research Journals. Some of the new points worked out in the thesis are: (1) a new study of the emergence of the idea of Parinama in the early Vedic literature; (2) attention has been drawn, for the first time, to the precise definition of Viparināma or Parināma as given by Yaska; (3) new light has been thrown on the problems of Tattväntara-Pariņāma, the process of Pariņāma - savsrsta-viveka and višesāvisesa - which occur in the Samkhya-Yoga works; (4) the problem of the relation between Pajjava or Paryāya and Pariņāma from the Agama passages is discussed for the first time in this manner; (5) a critical study of the Jain technical terms agurulaghy' has been attempted here for the first time; (6) further applications of ParyāyaParinama, viz., Dravya-paryāya and Guna-paryāya, Pariņāma and Parispanda, PrayogaParinama and Visrasa-Pariņāma, Artha-paryāya and Vyanjana-paryāya, as found in the later Jain dialectical works have been critically examined for the first time in a way done by the alitor; and (7) a new approach has been tried in the study of the nature of Pre-Isvarakssna Sankhya and the historical relation between Samkhya and Jain. In this way, by putting forward in this thesis, a critical study of the views of India's ancient thinkers of the two important scliools on Parinama, the author has attempted to contribute to the understanding of the concept of 'Permanence and Change, a concept of gret significance in the history of philosophy as well as modern knowledge as a scientific principle.
