Swami Kriyanana, born J. Donald Walters (born May 19, 1926), is a direct disciple of the yogi Paramahansa Yogananda and had many hours of personal contact with him during the last four years of Yogananda's life (1948 – 1952). During this time Kriyananda became a minister for Self-Realization Fellowship, founded by Yogananda. Yogananda also asked him to teach Kriya Yoga, which Yogananda called the highest technique of Self-Realization.
