Picture Interpretation
The patient busying himself in paint (or in some medium) increases its effect upon him. Moreover the concrete study of, and concrete shaping of the image enforces a continuous study of it in all its parts so that it can develop its effects to the full. This lends it greater weight and driving power and these rough and ready pictures do produce an effect which I must admit is difficult to describe. A patient need only see once or twice how much he is freed from a wretched state of mind by working at a symbolic picture and he will always turn to means of release when things go badly for him.
