Jayarashibhatta's Tattvopaplavsimha (ca. 8th cent.) is considered to be an important work of the Caravaka (Charvak) philosophy. The Charvak philosophy rejects evidence other than the direct evidence, to the extent that it does not consider sky as an element in the five fundamental elements (earth, water, fire, air and sky). The manuscript of Tattvopaplavisimha was obtained from Patan (modern-day Patna) in 1926. It was published in the Oriental Series in 1940 and with an introduction in Hindi by Pandit Sukhlal Sanghvi in 1987. The historical work examines the definitions of the evidence as accepted by various arms of Indian philosophy. The present book reviews the refutation of various epistemological principles explained in Tattvopaplavsimha. ?????????? ??? ????????????????
