I have been thinking of what you say about form... I feel that a real living form is the natural result of the individual's effort to create the living thing out of the adventure of his spirit into the unknown.... and from that experience comes the desire to make the unknown known. By unknown I mean the thing that means so much to the person that he want to put it down - clarify something he feels but does not clearly understand... Making the unknown known.... if you stop to think of form as form you are lost.
