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.
As soon as you know the voice and understand what it is, the whole scene changes. The same world which was the ghastly battlefield of maya is now changed into something good and beautiful.
-Swami Vivekananda
