The distinction turns on a question of life. A sign is an agreed-upon shorthand — it points efficiently to something already known, something that could in principle be stated without it. A symbol is not efficient. It carries energy precisely because it gestures toward something that cannot yet be said, a knot of meaning the psyche has not yet metabolized. The cross, the mandala, the dream-figure who will not hold still — these are not illustrations of a doctrine. They are the site where transformation actually occurs, which means they must remain partially opaque. The moment you decode a symbol completely, pin its meaning down, reduce it to a message, it stops functioning. It becomes a sign, and the energy it was holding drains away.

This matters especially when someone arrives at therapy, or at a dream, or at a piece of mythology, looking for the answer — which is to say, looking for relief from the tension of not-knowing. The symbol does not deliver relief. It holds the tension at a higher charge until something in the psyche shifts. Jung's insistence on *real* symbol is a refusal to let the psyche off the hook early, a refusal to let meaning collapse into information before the transformation it points at has actually happened.
