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 day and night, I am of the essence of that Supreme Existence, Knowledge, Bliss--what fear and anxiety have I? This body, mind, and intellect are all transient, and That which is beyond these is myself.
-Swami Vivekananda
