Vācaspati Miśra
Vachaspati Mishra was a ninth or tenth century Indian Hindu philosopher of the Advaita Vedanta tradition. He wrote so broadly on various branches of Indian philosophy that later Indian scholars called him “one for whom all systems are his own”, or in Sanskrit, a sarva-tantra-sva-tantra. Vācaspati Miśra was a prolific scholar and his writings are extensive, including bhasya (commentaries) on key texts of almost every 9th-century school of Hindu philosophy with notes on non-Hindu or nāstika traditions such as Buddhism and Carvaka....
