The sacred subject of the eternal, living spiritual culture of the Upanishads and their journey to the West deserves attention of a wider public. This book is a comprehensive treatment of the broad achievements of India's civilization and spiritual culture as it is revealed through the works of Western scholars.
The book one must read to learn natural sciences is the book of nature. The book from which to learn religion is your own mind and heart.
-Swami Vivekananda
