________________ Preface tedium of scholarly life does not stand in the way on account of the constant encouragement and words of appreciation received from him. I should also thank Samani Smitaprajna, Ujjvalaprajna and Chinmayaprajna for their unstinted co-operation and scholarly suggestion on many an occasion. My thanks are also due to Dr. M.P. Mehta who prepared the nice press copy of the book and carefully revised the proofs. The assistance rendered by Sri R.S. Soni from time to time was also valuable. I also thank Sri Sudhir Kumar, Librarian, and Sri Ramesh Dan charan, Library Assistant, for the quick discharge of their job in supplying necessary reference material to me. The workers of the press also deserve my thanks for printing the book so quickly and efficiently. Jain Vishva Bharti, Ladnun (Rajasthan) March 31, 1986. Nathmal Tatia Director Research Department
