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.
They alone live whose lives are in the whole universe, and the more we concentrate our lives on limited things, the faster we go towards death. Those moments alone we live when our lives are in the universe, in others; and living this little life is death, simply death, and that is why the fear of death comes.
-Swami Vivekananda
