Tracing the projection of everything in the universe to the supreme Brahman (Purusha, or supreme Person), the Purushasukta, a short hymn of eighteen Riks, contains a succinct description of the Vedanta philosophy, which deals with the relation between man, God, and the universe. It is sung on many occasions; it is recited daily by millions wedded to the search for the supreme. This Sukta finds a place in all the Vedas, with slight variations. This shows its supreme importance.
Live for an ideal, and that one ideal alone. Let it be so great, so strong, that there may be nothing else left in the mind; no place for anything else, no time for anything else.
-Swami Vivekananda
