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.
Where God is, there is no other. Where the world is, there is no God. These two will never unite. Like light and darkness. That is what I have understood from Christianity and the life of Jesus. Isn't that also Buddhism? Isn't that Hinduism? Isn't that Islam? Isn't that the teaching of all the great sages and teachers?
-Swami Vivekananda
