Brhadaranyaka Upanishad - This book presents a lucid exposition of select portions of this Upanishad in the light of modern thought and modern needs. The Revered Swami has done this by freely drawing from contemporary scientific thought, biology, and physics, and by laying stress on the relevance of Vedantic ideas to these areas of modern thought.
Karma is the eternal assertion of human freedom. If we can bring ourselves down by our karma, surely it is in our power to raise ourselves by our own karma.
-Swami Vivekananda
