This extraordinary treatise explores parallel passages from the Bible and the Hindu scriptures to reveal the essential unity of all religions. Swami Sri Yukteswar is renowned as the revered guru of the great pioneer of yoga in the West, Paramahansa Yogananda (author of Autobiography of a Yogi). In this remarkable work - composed in the year 1894 at the request of the great Indian sage, Mahavatar Babaji - Sri Yukteswar outlines the universal path that every human being must travel to enlightenment. He also explains the vast recurring cycles of history - the yugas that mark the upward ascent of human consciousness over millenniums - amid the ever-changing panorama of turbulent world events.
