Charles Johnston's classic translation and commentary on one of the most profound of ancient sacred texts. The book also contains three introductory articles by Johnston, which shed much light on the Upanishads, their place in history, their influence and connection to other spiritual philosophies of the world. "The great Upanishads were compiled as Instructions for disciples preparing for Initiation. They contain philosophical teaching, and also many stories, generally in the form of spirited dialogues, of great beauty and eloquence, or ironical, but always radiant with spiritual wisdom. If we think of what is here translated as a part of these Instructions, we shall have little difficulty in understanding its significance. . . . "A single principle links together the great Upanishads and their diverse parts, like jewels strung on a golden thread: the oneness of the Soul and the Oversoul. When we have found the Soul, our inmost real Self, we have thereby found the Oversoul, the Supreme Self of all Being. This is the goal."-Charles Johnston

Swami Vimalananda, who was one of the outstanding scholarly monks of the Ramakrishna Order, has given a mastery introduction to the translated work. It supplies a guideline to the reader in arriving at the facts, expressions, customs, concepts, traditions, and doctrines that find their origin or a place in the text.
