In the center is the empty hub of the wheel, a realm of pure not-time. Thirty spokes converge upon a single hub; It is on the hole in the center that the use of the cart hinges.
Von Franz uses the Taoist image of the empty hub to locate the Self beyond temporal consciousness, identifying the centre of the psychic mandala as a realm untouched by clock-time.
