Swamiji Vethathiri Maharishi was born in 1911 in an indigent weaver's family in South India. Though he had very little formal schooling, in his later life he became a qualified physician in Ayurveda, Siddha, and Homoeopathy. Several years of intense meditation led to his enlightenment at the age of 35. Vethathiri led the life of a householder until he was 50, and then changed the course of his life from being a businessman to teaching and writing about his experiences of divine revelations. He has published many books in English and Tamil.
