Mahavatar Babaji is the name given to an Indian saint and yogi by Lahiri Mahasaya and several of his disciples, who reported meeting him between 1861 and 1935. Paramahansa Yogananda described some of these meetings in his book Autobiography of a Yogi, including a first-hand report of Yogananda's meeting with the yogi. According to Yogananda's autobiography, Babaji has resided for at least hundreds of years in the remote Himalayan regions of India, seen in person by only a small number of disciples and others.The deathless Master is more than 2000 years old. He belongs to a very powerful lineage of Siddha Boganthar and Rishi Agastya as his Gurus. He acquired this deathless, non-perishable body through tough yogic kriyas.
