In 1946, Paramahansa Yogananda, one of modern India's greatest yogis, revealed in his classic "Autobiography of a Yogi," the existence of a Christ-like saint, an immortal yogi, Mahavatar Babaji. Yogananda related how Babaji had for centuries lived in the Himalayas guiding many spiritual teachers at a distance, usually without their even knowing it.
He was a great siddha, one who had overcome ordinary human limitations, and who worked silently for the spiritual evolution of all humanity, behind the scenes. He also revealed that Babaji was the one who had taught a powerful series of yogic techniques, know as "Kriya Yoga," to Lahiri Mahasaya, around 1861, who subsequently initiated many others, including Yogananda`s own Christ-like guru, Sri Yukteswar, some thirty years later. Yogananda spent 10 years with his guru before Babaji himself appeared to him, and directed him to bring the sacred science of Kriya to the West. Yogananda fulfilled this sacred mission from 1920 to 1952, when he attained mahasamadhi. - Marshall Govindan
