Peace always begins within each of us. Our ability to create in the world depends on our ability, first, to work to create peace in our own lives. It's much easier to advocate peace on Earth than it is to be able to bring peace your own home. Or your own heart.
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.
