Shankaracharya (Sanskrit: शङ्कराचार्य, IAST: Śaṅkarācārya, "Shankara-acharya") is a religious title used by the heads of amnaya monasteries called mathas in the Advaita Vedanta tradition of Hinduism.
[1] According to a tradition developed in the 16th century, Adi Shankara set up four monasteries known as Mathas or Peethams, in the North, South, East and West of India, to be held by realised men who would be known as Shankaracharyas.
They would take on the role of teacher and could be consulted by anyone with sincere queries of a spiritual nature.
[2][3] Another monastery Kanchi Kamkoti Peeth in south India also derives its establishment and tradition to Adi Shankara, however its heads are called "Acharya" or "Jagadguru" instead of "Shankaracharya".
