* This is the extended edition including an extensive preface by Swami Vivekananda, the chief disciple of the 19th century mystic Ramakrishna Paramahansa and the founder of the Ramakrishna Math and the Ramakrishna Mission. He gives us deep insights about Yoga and the Ultimate Goal of Life.

Yoga is a subject which has enthralled the attention of the world from time out of mind. No one has really done justice to such a grand system, though there have been, now and then, innumerable attempts.
