A hermit must have a deep experience of communion with humanity. Without this, you cannot be a hermit, because you would only be lonely. You would not be really solitary. To be alone and cut off from others would make you very unhappy, but to be alone, and to be deeply united with others, in deep communion, that is a possibility for which many people long. That is what I call solitude—over and against loneliness.
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.
