Art,its definitions are legion, its meanings multitudinous, its importance often debated.  But amid the many contradictory definitions of art, one has always stood the test of time, from the Upanishads in the East, to Michelangelo in the West: art is the perception and depiction of the sublime, the transcendent, the beautiful, the spiritual.
Art is a window to The Infinite, and opening to the goddess, a portal through which you and I, with the help of the artist, may discover depths and heights of our soul undreamed of by the vulgar world. Art is the eye of the spirit, through which the sublime can reach down to us, and we up to it, and be transformed, transfigured in the process.
Art, at its best, is the representation of your very own soul, a reminder of who and what you truly are and therefore can become."
Ken Wilber
