________________ INTRODUCTION XV tioned Sasadhara and Gangesa; moreover, it is controversial that he possessed good knowledge of Navya-Nyaya; again, nowhere in the Jaina literature it is said that Gunaratna, the author of Saddarsanasamuccayatika, has written Tippana on NSD. So, we are inclined to keep the question of the identity of Gunaratnagani, the author of Nyaya-siddhantadipa-Tippana, open. Evaluation of Sukhabodhika lippanika Sukhabodhika Tippanika is not merely an annotation-type commentary, as its title suggests. It is a good expository commentary. It explains the texts it comments on with lucidity and authenticity. It evinces deep study and understanding of Navya-Nyaya. It expounds subtle points of Navya-Nyaya. At times, it draws fine line of distinction between cognate or closely related concepts or terms. At several places it discusses readings too. As an instance in point we quote : atra mulapathe niragnitvad iti patho 'suddha iva laksyate (p. 531). Sometimes it clearly points out as to who are intended by such terms as acaryah, pracam, etc. It clarifies that there pracam stands for Vacaspatimisranam. It refers to and quotes from authoritative texts and authors like Vatsyayana, Vacaspati Misra, Udayana, Kusumanjaliprakasa, Lilavati, Gangesa, Yajnapati Upadhyaya, Paksadhara Misra, Bhaskara, etc. It ably.discusses some grammatical points and there in support of his exposition quotes Panini, Mahabhasyakara Patanjali and Nyasakara. This very well testifies to Gunaratna's erudition and scholarship. The commentary raises doubts and then answers them lucidly and convincingly. This is its main feature. It recapitulates or summarises elaborate discussions or expositions. These recapitulations and summaries are marked by the phrases like ayam asayah, ayam arthah, niskarsas tu, iti bhavah, iti praghattakarthah. Jaina Navya-Nyaya Scholars Jaina tradition has very few Navya-Nyaya scholars to its credit. First we have Gunaratnagani of 14th century A.D., who wrote Tippana on Sasadhara's Nyayasiddhantadipa. Then comes Bhuvanasundarasuri (c. 1390-1450 A.D.) who was a learned Jaina scholar of Navya-Nyaya. His very good commentary on Vadindra's Mahavidya-vidambana called Mahavidya-vidambana-tika bespeaks of his excel1. Edited by M. R. Telang, Gaekwad Oriental Series, No. 12, 1920, Baroda.
