Sankaracharya was a prolific philosopher and commentator, who wrote influential works on the Upanishads, the Brahma Sutras, and the Bhagavad Gita. He also established four monastic centers (mathas) in different regions of India, and revived the tradition of Hinduism against the challenges of Buddhism and other schools.
