Explanation
The founder of four Mutts (monasteries) in the four corners of India was Adi Shankaracharya.
Adi Shankaracharya was a philosopher and theologian who lived in the early 8th century CE. He was a prominent figure in the development of Hinduism and is widely regarded as one of the most influential thinkers in Indian history.
Shankaracharya founded four monasteries or Mutts in the four corners of India - Jyotirmath in the North, Sringeri in the South, Govardhan Math in the East, and Kalika Matha in the West. Each of these Mutts was established to propagate and preserve the teachings of Advaita Vedanta, a school of Hindu philosophy that Shankaracharya helped to develop.
The Mutts established by Shankaracharya continue to be important centers of learning and pilgrimage for Hindus. They play a significant role in the preservation and dissemination of Hindu culture and philosophy in India and around the world.
