Vāchaspati Misra

Vachaspati Mishra (IAST: Vācaspati Miśra), was a ninth or tenth century Indian Hindu philosopher of the Advaita Vedanta tradition, who wrote bhashya (commentaries) on key texts of almost every 9th-century school of Hindu philosophy. and harmonised Shankara's thought with that of Mandana Miśra, who until the 10th century was the most authoritative exponent of Advaita Vedanta. He also wrote an independent treatise on grammar, ''Tattvabindu,'' or ''Drop of Truth'', which focuses on Mīmāṃsā theories of sentence meaning. Provided by Wikipedia
