Jayatirtha was a prominent philosopher and theologian in the Dvaita school of Vedanta, which emphasizes dualism between the individual soul and the supreme being, Vishnu. He lived during the 14th century in India and is known for his commentaries on the works of Madhvacharya, the founder of the Dvaita tradition. Jayatirtha is particularly recognized for his text, the Nyaya Sudha, which provides a detailed analysis of logic and epistemology within the Dvaita framework. His contributions helped shape the philosophical discourse of his time and continue to influence followers of the Dvaita tradition today.
