A great enlightened sage and Advaita Vedanta master, Nisargadatta Maharaj (1897-1981, born Maruti) spent his life as a householder and shopkeeper, until he met his guru, Sri Siddharameshwar, and began a serious mantra sadhana. On the death of his guru, he renounced his family and left for the Himalayas. He was later convinced to return to worldly life and a path of action, and devoted the rest of his life to meditation and the Vedantic teachings of his guru. He was known for his penetrating insight and no-nonsense style. His teachings are most well known through the enduring book, I Am That.
