Shankara (c. 700–c. 750)

Hindu philosopher who wrote commentaries on some of the major Hindu scriptures, as well as hymns and essays on religious ideas. Shankara was responsible for the final form of the Advaita Vedanta school of Hindu philosophy, which teaches that Brahman, the supreme being, is all that exists in the universe, everything else is illusion. Shankara was fiercely opposed to Buddhism and may have influenced its decline in India.
