Mystery: it is all around us, and we do not know it. But sometimes when we give it time and space, whether in deep peace or great anguish, it will come up behind us, or meet us face to face, or move within us, changing the way we see everything, and filling our hearts with joy and an upspringing of love that needs no direct object because everything is its object.
In a sense great music exists for the sake of its pauses; for instance, the pauses that occur in the middle of a Beethoven symphony. These pauses are of course quite unlike bits of ordinary silence, because the whole symphony has led up to them — they are held and defined, and the music goes on the other side of them. Such pauses are silence charged with meaning. Music transcends music by producing charged silence.
