When the true Self is known the jigsaw puzzle of the world gets solved, doubts end, and all misery vanishes. In Atmabodha, a lyric of sixty-eight mellifluous verses, Shankara gives us a lucid analysis of the nature of the Self and explains step by step how it can be realized. Swami Nikhilananda prefaces his delightful English translation with a masterly survey of the Upanishadic view of life.
All is the Self or Brahman. The saint, the sinner, the lamb, the tiger, even the murderer, as far as they have any reality, can be nothing else, because there is nothing else.
-Swami Vivekananda
