The symbol, however, is also an expression of the spiritual side, of the formative principle dwelling in the unconscious, for "the spirit appears in the psyche as instinct," as a "principle sui generis." So far as the development of human consciousness is concerned, this spiritual side of the symbol is the decisive factor. Over and above its "gripping" aspect the symbol also has a meaningful aspect: it is more than a sign; it assigns meaning, it signifies something and demands interpretation. It is this aspect that speaks to our understanding and rouses us to reflection, not just to feeling and emotionality. These two aspects working together in the symbol constitute its specific nature, unlike the sign or allegory which have fixed meanings. So long as the symbol is a living and effective force, it transcends the capacity of the experiencing consciousness and "formulates an essential unconscious component" -the very reason why it is so attractive and disturbing. Consciousness keeps on returning to it and circles round it fascinated, meditating and cogitating, thus completing the circumambulatio which recurs in so many dramatically enacted rites and religious ceremonies.
— Erich Neumann
Neumann is pointing at something that the sign-world around us systematically obscures: the difference between a fixed meaning and a living one. A sign exhausts itself in its referent — stop means stop, and once you know it, there is nothing left to circle. The symbol refuses this. It keeps the gap open. It names something that cannot be fully named, which is why consciousness cannot simply learn it and move on; it returns, orbits, meditates — the circumambulatio — not from failure of understanding but because the symbol contains more than any single encounter can extract.
What Neumann calls the spiritual side, the "principle sui generis," is the formative pressure working upward through the image. Spirit appears in the psyche as instinct — not as doctrine descending from above, but as an organizing urgency already moving in the depths. This matters because the temptation is always to settle the symbol too quickly: to interpret it once, to fix its meaning, to convert the living thing into a useful allegory. The moment that happens, the circulation stops. What drew consciousness back again and again — the irreducible surplus, the unsettlement — is gone. The circumambulatio is not a ritual decoration. It is the sign that the symbol is still alive, still formulating something the experiencing consciousness has not yet metabolized.
