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 disciple must have great power of endurance. Life seems comfortable; and you find the mind behaves well when everything is going well with you. But if something goes wrong, your mind loses its balance. That is not good. Bear all evil and misery without one murmur of hurt, without one thought of unhappiness, resistance, remedy, or retaliation. That is true endurance; and that you must acquire.
-Swami Vivekananda
