Vyasatirtha

Vyāsatīrtha (), also called Vyasaraja or Chandrikacharya, was a Hindu philosopher, scholar, polemicist, commentator and poet belonging to the Madhwacharya's Dvaita order of Vedanta. As the rajaguru of Vijayanagara Empire, Vyasatirtha was at the forefront of a golden age in Dvaita which saw new developments in dialectical thought, growth of the Haridasa literature under bards like Purandara Dasa and Kanaka Dasa and an increased spread of Dvaita across the subcontinent. He himself composed many kīrtanas in Kannada and Sanskrit.

Three of his polemically themed doxographical works Nyayamruta, Tatparya Chandrika and Tarka Tandava (collectively called Vyasa Traya) documented and critiqued an encyclopaedic range of sub-philosophies in Advaita, Visistadvaita, Mahayana Buddhism, Mimamsa and Nyaya, revealing internal contradictions and fallacies. His Nyayamruta caused a stir in the Advaita community across the country requiring a rebuttal by Madhusudhana Saraswati through his text, Advaitasiddhi. He is considered as an amsha of Prahlada in the Madhva Parampara.
