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.
This I have seen in life -- those who are overcautious about themselves fall into dangers at every step; those who are afraid of losing honor and respect, get only disgrace; and those who are always afraid of loss, always lose.
-Swami Vivekananda
