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.
The more we grow in love and virtue and holiness, the more we see love and virtue and holiness outside. All condemnation of others really condemns ourselves. Adjust the microcosm (which is in your power to do) and the macrocosm will adjust itself for you.
-Swami Vivekananda
