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.
The value of a human being can be measured by what he or she most deeply wants. Be free of possessing things. Sit at an empty table. Be pleased with water, the taste of being at home.
