Darkness, whether in mood or in night, is natural. So if we flow with the black bile of melancholia and endure the terrible darkness of depression, eventually we will break through into the light of joy. This is the Tao (the Way) of darkness or depression--this is the Mystery of its evolution.
All I know for sure is that dreams are the pictures of states wanting to turn into processes. Dreams are maps of the beginning of an otherwise unchartered trip into the unknown. They are pictures of the unknown which appear in many channels. Because process work is body-oriented, I put a stress upon feelings, but dreams are not pictures of just feelings; they are pictures of the way the unknown is showing itself in a given moment.
We are neither this way nor that; we are a body which is in the midst of change and evaporating. We are timeless, thousands of years old, and involved with processes which go beyond our present identity. This gives us an eternal feeling, but one which is realizable right here in the moment.
