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.
Think always, I am ever-pure, ever-knowing, and ever-free. How I can do anything evil? Can I ever be fooled like ordinary people with the insignificant charms of lust and wealth? Strengthen the mind with such thoughts. This will surely bring real good.
-Swami Vivekananda
