p. 197-8). He was a great logician and commentator of his time, and was one of the gems of Nalanda University. He is said to have flourished in about 700 A.D. His commentary on the present treatise is very learned and helpful to understand fully the position and motive of Dinnāga in writing the present work. Almost all important portions of this commentary have been translated into French by S. Yamaguchi and H. Meyer from its Tibetan translation, and again translated into English by me and added as notes to my English translation of the treatise.
In concluding the preface I should offer my sincere thanks to the authorities of the Adyar Library, especially the Director, Dr. G. Srinivasamurti, B.A, B.L., M.B. & C.M., Vaidyaratna, and the Editor Dr. C. Kunhan Raja, M.A., D. Phil. (Oxon.) for kindly publishing this book in the Adyar Library Series. I should like also to thank M. Bhikshu Arya Asanga (formerly A. J. Hamerster) Jt. Director and Curator for the Western section of the Library for the help he has kindly rendered by going through some portions of my English translation of the French passages. However, I must say that I hold myself responsible for those portions as printed in this volume.
