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.
Your Atman is the support of the universe -- whose support do you stand in need of? Wait with patience and love and strength. If helpers are not ready now, they will come in time. Why should we be in a hurry? The real working force of all great work is in its almost unperceived beginnings.
-Swami Vivekananda
