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.
All power is within you. You can do anything and everything. Believe in that. Do not believe that you are weak; do not believe that you are half-crazy lunatics, as most of us do nowadays. Stand up and express the divinity within you.
-Swami Vivekananda
