This book is an illuminating sequel to the author's earlier well-researched 'Journey of the Upanishads to the West', both focusing on the glorious Oriental literary heritage to the world at large.
Change is always subjective. All through evolution you find that the conquest of nature comes by change in the subject. Apply this to religion and morality, and you will find that the conquest of evil comes by the change in the subjective alone. That is how the Advaitic system gets its whole force, on the subjective side of man.
-Swami Vivekananda
