So many of our problems arise because we always feel cut off from something we need. We do not feel whole and therefore turn expectantly toward other people for the qualities we imagine missing in ourselves. All of the problems of the world, from one person’s anxiety to warfare between nations, can be traced to this feeling of not being whole.
