The story of Lahiri Mahasaya receiving initiation into Kriya Yoga by the yogi Mahavatar Babaji in 1861 is recounted in "Autobiography of a Yogi". Yogananda wrote that at that meeting, Mahavatar Babaji told Lahiri Mahasaya, "The Kriya Yoga that I am giving to the world through you in this nineteenth century, is a revival of the same science that Krishna gave millenniums ago to Arjuna; and was later known to Patanjali, and Christ, and to St. John, St. Paul, and other disciples." Yogananda also wrote that Babaji and Christ were in continual communion and together, "have planned the spiritual technique of salvation for this age."
