This translation captures the meaning and beauty of the twelve principal Upanishads, omitting a few passages. Original text is not given. An excellent version for the general reader.
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
