This is surely the most extraordinary spiritual biography of the twentieth century. Written with fearless candor by a Yoga adept (siddha) whose spiritual genius stands unchallenged, it chronicles the inner ups and downs following the awakening of the serpent power (Kundalini-shakti). As his vivid descriptions show, Swami Muktananda experienced the whole gamut of mystical states, and his book affords one a unique glimpse into the mind of a great master in the making.
