The Nyayapravesa of Dinnaga
By Vidhushekhara Bhattacharya
Summary
The Nyayapravesa of Dinnaga is a foundational Buddhist logic text attributed to the 8th-century philosopher Dinnaga. Originally titled *Nyayapravesa*, it is also known as *Nyayadvara* (Rgyal-ba-rigs-pa-la-rjug-pa) in Tibetan and *Yiming* ( logical analysis) in Chinese. The work systematically explores Buddhist epistemology and logic, emphasizing valid cognition (*pramana*) through ten chapters. It has been influential in Tibetan Buddhist scholarship, with commentaries like Haribhadra’s *Vrtti* and Parsvadeva’s *Pafijika*. The text was preserved in Sanskrit, Tibetan, and Chinese versions, with the Tibetan translation directly from Sanskrit and the Chinese version derived from a Sanskrit original. Scholars like Vidyabhusana and Suyura have studied the text, with some initially misattributing the Chinese version to Nagarjuna due to translation errors. However, Tibetan sources and Dinnaga’s own commentary on his *Pramanasamuccaya* (PS) confirm his authorship. The *Viimalamalavati*, a commentary on Dinnaga’s PS, further supports this attribution by referencing the *Nyayapravesa*. The work’s structure includes prose and verse sections, distinguishing it from other logical treatises like the *Nyayatarkadvirasistra*. The *Nyayapravesa* remains a critical resource for understanding Buddhist logic, with editions published in the Gaekwad’s Oriental Series and references in modern scholarship. Its analysis of cognition, inference, and debate principles continues to be relevant in Buddhist studies.
Conclusion
The Nyayapravesa of Dinnaga represents a pivotal contribution to Buddhist logic, clarifying the relationship between Buddhist epistemology and Nyaya principles. By analyzing the text's titles, commentaries, and cross-cultural translations, this study establishes that the Nyayapravesa and Nyayadvira are identical works, dispelling prior misattributions to Nagarjuna and affirming Dinnaga's authorship. The document's significance lies in its dual role as a bridge between Buddhist and Hindu logical traditions and its influence on subsequent commentaries, such as those by Haribhadra and Prasangabhuta. The findings underscore the importance of textual accuracy in attributing authorship and highlight the Nyayapravesa's enduring impact on the development of Buddhist logical discourse across Sanskrit, Tibetan, and Chinese traditions. This work not only resolves historical ambiguities but also enriches the understanding of Dinnaga's role in shaping Buddhist epistemology.
