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.
Bless people when the revile you. Think how much good they are doing by helping to stamp out the false ego. Hold fast to the Atman, think only pure thoughts, and you will accomplish more than a regiment of mere preachers.
-Swami Vivekananda
