Achyuta Krishnananda Tirtha (1650 – 1750 CE) was a writer on Advaita Vedanta. He hailed from Tamil Nadu, studied under Svayamprakashananda Saraswati, the teacher of Vedanti Mahadeva (who wrote a commentary on Vishnu Sahasranama in 1694 CE), Sarvajna, and Advaitananda, all three being eminent scholars. He is known for his erudition in interpreting canonical texts, which explain the tenets of Advaita philosophy. Krishnalankara of Achyuta Krishnananda Tirtha is a commentary on Siddhantalesha Sangraha, a well known work of Appaya Dikshita, who brought together the views of different philosophers on the monistic school of Shankara, but made no attempt to harmonize the differences. Another commentary of the writer is Vanamala on Shankara’s Bhashya on Taittiriya Upanishad. He also wrote commentaries on Katha Upanishad-bhashyatika and Chandogya Upanishad Vivarana. Bhavadipika is a commentary on Vacaspati Mishra’s Bhamati which, in turn, is a commentary on Shankara Bhashya on Brahma Sutra. He
