A simple translation of the Upanishad containing the original text in Devanagari, transliteration of each shloka, and word-for-word English rendering followed by a running translation and notes based on Shankaracharya's commentary.
The whole universe is one in the Atman. That Atman when it appears behind the universe is called God. The same Atman when it appears behind this little universe, the body, is the soul. This very soul, therefore, is the Atman in us.
-Swami Vivekananda
