Among the many biographies of Swami Vivekananda, the present book has a place of special importance, as it is a historical review of the great life and contribution of the great Swami by one whose scrutiny of facts, analysis of events, and unbiased search for truth won him a place of honour among the eminent historians of the twentieth century. The author has deliberately avoided discussions on mystic experiences and philosophical ideas of the Swami and has portrayed him purely on historical lines.
The essential thing in religion is making the heart pure; the Kingdom of Heaven is within us, but only the pure in heart can see the King. While we think of the world, it is only the world for us; but let us come to it with the feeling that the world is God, and we shall have God.
-Swami Vivekananda
