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.
No authority can save us, no beliefs. If there is a God, all can find Him. No one needs to be told it is warm; all can discover it for themselves. So it should be with God. He should be a fact in the consciousness of every person.
-Swami Vivekananda
