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.
Let each one of us pray day and night for the downtrodden millions who are held fast by poverty, priestcraft, and tyranny. Pray day and night for them. I care more to preach religion to them than to the high and the rich.
-Swami Vivekananda
