Shall I inform you of a better act than fasting, alms, and prayers? Making peace between one another: enmity and malice tear up heavenly blossoms by the roots.
~ Muhammad
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.
