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 less passion there is, the better we work. The calmer we are, the better for us and the more the amount of work we can do. When we let loose our feelings, we waste so much energy, shatter our nerves, disturb our minds, and accomplish very little work.
-Swami Vivekananda
