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.
Center yourself to God and PRAY night and day "without ceasing." ALL you do, think, or read can be made into prayer. Great music, art, literature, architecture, friendships are, or can be, forms of prayer. What is gained by prayer can never be lost. PRAYER is eternity breathing in time.
