He established the [[Navya-Nyāya]] ("New Logic") school. His ''Tattvacintāmaṇi'' (The Jewel of Thought on the Nature of  Things), also known as ''Pramāṇacintāmaṇi'' (The Jewel of Thought on the Means of Valid Knowledge), is the basic text for all later developments. The [[logician]]s of this school were primarily interested in defining their terms and concepts related to non-binary logical categories.
