________________ PREFACE OF THE SECOND EDITION The Kashi Prasad Jayaswal Research Institute has great pleasure in offering the second edition of Abhidharmadipa to the world of scholars. The first edition of the book had received a generous welcome and brought many private communications and critical appreciations from scholars in India and abroad. The publication of the book in 1959 by the Institute was regarded by some renowned specialists in the field as "a capital event for scholars interested in the history of the Abhidharma class of Buddhist scriptures." It soon ran out of stock and there was a persistant demand for its second edition. To meet with this sacred demand the Institute took it up in right earnest and expresses its thanks to Dr. P. S. Jaini for having accomplished the work within so short a time. It is hoped that the present edition also will receive its due from the world of scholars. 28th Oct, 1977 * J. S. Jha Acting Director
