Shankaracharya

Shankaracharya (IAST: Śaṅkarācārya, Shankara acharya) is a commonly used title of heads of monasteries called mathas in the Advaita Vedanta tradition. The title derives from Adi Shankara, an 8th-century CE reformer of Hinduism. He is honored as Jagadguru, a title that was used earlier only to Krishna.
