Number, as it were, lies behind the psychic realm as a dynamic ordering principle, the primal element of which Jung called spirit. As an archetype, n… - Marie-Louise von Franz

Always at bottom there is a divine revelation, a divine act, and man has only had the bright idea of copying it. That is how the crafts all came into existence and is why they all have a mystical background. In primitive civilizations one is still aware of it, and this accounts for the fact that generally they are better craftsmen than we who have lost this awareness. If we think that every craft, whether carpenter's or smith's or weaver's, was a divine revelation, then we understand better the mystical process which certain creation myths characterize as God creating the world like a craftsman. By creating the world through such a craft he manifests a secret of his own mysterious skill.

To sum up: numbers appear to represent both an attribute of matter and the unconscious foundation of our mental process. For this reason, number forms, according to Jung, that particular element that unites the realms of matter and psyche. It is “real” in a double sense, as an archetypal image and as a qualitative manifestation in the realm of outer-world experience.

In other words, the idea of the philosopher's stone of the alchemists is identical with the idea of the glorified body. This offers an archetypal approach to some Eastern ideas, because in different Eastern yoga practices and meditation the goal is to produce within oneself the so-called diamond body which is an immortal nucleus of the personality.
