________________ Out of these three commentaries on PDS, Kiranavali became more popular than the other two. Udayana is, no doubt, a prolific writer on Nyaya-Vaisesiku system. His polemic discourse is very subtle and lucid. His arguments are poignant. Unfortunately his Kiranavali is incomplete, and there also his favourable approach to Nyaya system is conspicuous. The same is the trend of Vyomasiva. Moreover, Vyomasiva 'lacks the vigour of Udayana. Hence the relative merit of Sridhara is enhanced more naturally. That is why perhaps the study of Nyayakandali got momentum in later period. Nyayakandali Sridharacarya has secured an eminent place in the scholastic galaxy of the Nyaya-Vaisesika system by his Nyayakandali-a very valuable commentary on PDS. Sridhara himself gives his short bio-data in the colophon of the Nyayakandali. From it we know that the date of the composition of Kandali was 913 Saka Samvat i.e. 991 A.D. His native place was Bhurisrestha in Radha (modern Bhursut in Howrah district ) in Bengal. His father was Baladeva and mother was Acchoka. He wrote Kandali at the request of Sri Pandudasa, who according to Naracandra and Rajasekhara was a pupil of Sridhara. Dr. Jetly suggests that Pandudasa was the king of Radha.? Nyayakundali was recognized as a standard work for study in course of time. We find Kandali referred to by Abhayadeva Suri (11th Cent. A.D.) in his Vadamaharnavu, by Devasuri ( 12th Cent. A.D.) in his Syadvadaratnakara, by Upadhyaya Abhayatilaka ( 13th Cent. A.D.) in his Nyayalankara Tippana and by Gunaratna Suri ( 15th Cent. A.D.) in his commentary of Haribhadra's Saddarasanasamuccaya. 1 In support of this Pt. Phanibhusana, quotes a verse from the second act of Prabodhacandrodaya Nataka by Ktsna Bhatta, a son of Sridhara. He refers to a commentary of this verse which states that Bhursut is the present name of this Bhurispsti and observes that there is a famous village Bhurasuta in the present Hugali Dist. See. Nyaya Paricaya, Intro. p. 4. 2 Pt. Phanibhusana however refers to the opinion of historians according to whom Pandudasa was a Kayastha king who ruled Radha in 10th 11th Cent. A.D. He was a Buddhist and as such different from the Pandudasa mentioned by Sridhara (Ibid. p. 4). But Dr. Jetly sees no objection in accepting the king Panoudasa to be the pupil of Sridhara.
