and logic in particular and of the entire medieval Indian epistemology and logic
in general. There are several works composed by him in this area, among which
"Pramāṇa Samuccaya" and "Nyāya Praveśa" are most important. "Pramāṇa
Samuccaya" is not available in its complete form, even though some of its chapters
have been restored from Tibetan and other sources. However "Nyāya Praveśa" is
available to us in its full form. An attempt has been made here to translate it in
English for the benefit of English language readers. The text is presented here in
Roman script with a view to have wider readership. Explanatory notes have also
been provided to clarify some knotty points.

"Nyāya Praveśa" is a classical work pertaining to the modes of knowing and
reasoning in the Buddhist tradition. For centuries it has been studied as a manual
of the Buddhist theory of knowledge in India, Tibet, China, and other countries.
It provides a foundation to the famous Buddhist art of debate (vāda-vidhi). There
are several Tibetan and Chinese commentaries and sub-commentaries on "Nyāya
Praveśa" apart from the ones in Sanskrit. This accounts for its significance and
popularity among classical scholars.

In a cryptic, but succinct, manner "Nyāya Praveśa" presents Diṅnāga's views
on the nature of perception and inference and their fallacies. It also elaborately
discusses the modes of argumentation and refutation along with their fallacies.
