Swami Vivekananda was one of the great religious minds of the 19th century. His appearance in the Congress of World Religion in America was a momentous event in the history of religion, where he changed the western view of Vedanta Hindu philosophy. What is the substance of Vivekananda's interpretation of Vedanta? And how relevant is it to 20th century man? In this revised volume, Gautam Sen pieces together the representative portions of the Swami's philosophy and ties them up with a running commentary of his own.
