Self-knowledge is a collection of six lectures delivered by Swami Abhedananda in America. These lectures contain mainly the rich thoughts of the Upanishads. The Self has formed the central theme of the Swamis discussion as the Self or Atman is the fountain-head of all things of the world. Swami Abhedananda has taught in this volume that knowledge of the Self lies at the root of all knowledge whether of science philosophy or religion. Men who desire intellectual moral and spiritual development must learn to discriminate between spirit and matter soul and body and then realize Atman which is the eternal ground of the universe.
