as invalid proofs. He deviated also from all definitions of perception and inference as current in his time, and gave his own definitions' against the views of Akşapáda and Vatsyâyana. Dinnaga was the author of the Nyayapraves'asútra, the only available work of his in Sanskrit, which is now being printed for publication in the Gaekwad's Oriental Series. All that we know of his personal history comes from Tibetan sources, and the information we obtain from these sources may be summarised thus: Dinnaga was born of a Brahmin family in Simhavaktra near Kanchi in the Madras Presidency. He was subsequently admitted into the Buddhist Church of the Hinayana by Någadatta; thereafter he became the disciple of Vasubandhu (280-360 ) and studied the scriptures of both Hinayâna and Mahayana. He was then invited to Nalanda where he defeated many Tîrthikas, and since then he was known as the Fighting Bull or a Bull in Discussion. He travelled from place to place, and was mainly engaged in defeating Tirtha logicians and converting them to Buddhist faith. His works were translated into Chinese by Paramartha ( 499-569) and he is reputed to be the author of the following works on logic besides the Nyayapraves'a already refered to.
