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.
Nature grinds all of us. Keep count of the ounce of pleasure you get. In the long run, nature did her work through you, and when you die your body will make other plants grow. Yet we think all the time that we are getting pleasure ourselves. Thus the wheel goes round.
-Swami Vivekananda
