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.
Mind you, this is life's experience: if you really want the good of others, the whole universe may stand against you and cannot hurt you. It must crumble before your power of the Lord Himself in you if you are sincere and really unselfish.
-Swami Vivekananda
