"Pain (any pain--emotional, physical, mental) has a message. The information it has about our life can be remarkably specific, but it usually falls into one of two categories: We would be more alive if we did more of this and Life would be more lovely if we did less of that. Once we get the pain's message, and follow its advice, the pain goes away."

SOLIDAO, LONELINESS. What is it that we call loneliness. It can't simply be the absence of others, you can be alone and not lonely, and you can be among people and yet be lonely. So what is it? ... it isn't only that others are there, that they fill up the space next to us. But even when they celebrate us or give advice in a friendly conversation, clever, sensitive advice: even then we can be lonely. So loneliness is not something simply connected with the presence of others or with what they do. Then what? What on earth?
