Two prisoners whose cells adjoin communicate with each other by knocking on the wall. The wall is the thing which separates them but is also their means of communication. It is the same with us and God. Every separation is a link. The interpretation of dreams is the royal road to a knowledge of the unconscious activities of the mind. A test of what is real is that it is hard and rough. Joys are found in it, not pleasure. What is pleasant belongs to dreams. |
