The purpose of music is not that it should be judged, but that it should become our substance. Music is a spiritual food for which there is no substitute; he who does not feed on it will live in spiritual anemia until death. There is no complete spiritual life without music, for the human soul has regions which can be illuminated only by music. The purpose of music is to understand better: to evolve and expand our inner world. Legends of many peoples deem music to be of divine origin; thus, when we have reached the boundaries of human understanding, music points beyond, into a world that cannot be explored but merely guessed at.
