To listen to music or to sing a chant is to do something that has no practical purpose; it is just celebration and praise; it is just tasting the joy and beauty of life, the glory of God. Listening to it, even in the midst of a very purposeful day, reminds us to add the other dimension to our experience, the dimension of meaning, that makes it all worthwhile.
Silence is no passive thing. It is a vibrant presence which fills any vacuum in sound and conveys its own living quality. Most of us know the truth of the phrase "the silence that sounds," and the old adage "silence is golden" means more than just that it is safe or wise. It means that it is golden in the sense of being filled with light.
