Also from Wikipedia: “[George] Harrison became a vegetarian in the late 1960s, and a devotee of the Indian mystic Paramahansa Yogananda, a guru who proselytised Kriya yoga, after he was given Yogananda’s Autobiography of a Yogi by Ravi Shankar. (Yogananda and three other major figures from Kriya yoga, Sri Mahavatar Babaji, Sri Yukteswar Giri, and Sri Lahiri Mahasaya appear on the cover of Sgt. Pepper’s Lonely Hearts Club Band.)”
