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.
Books are infinite in number and time is short. The secret of knowledge is to take what is essential. Take that and try to live up to it.
-Swami Vivekananda
