Jung reaches for an apocryphal Jesus saying, a Taoist cosmology, and a fifteenth-century cardinal's metaphysics in a single paragraph — not to show off the breadth of his library, but because he needs that many witnesses to establish one stubborn fact: the psyche has always organized itself around the problem of opposites, and it has never solved it by eliminating one side. The coniunctio is not a merger in which tension disappears; it is a state in which tension becomes bearable because it has been fully inhabited. "Fixed" is the alchemical word for what no longer volatilizes and escapes — the contents that used to flee into spirit or matter, into abstraction or compulsion, now hold their form in the vas of consciousness.

What Jung is quietly pressing against here is the fantasy that wholeness is peaceful. The saying he cites — outside as inside, male with female, neither — is explicitly paradoxical: it does not resolve the binary by choosing one pole. The eschatological frame matters too. These are end-time images, images of what becomes possible at the extreme limit of endurance. The alchemists were not optimists. They sat with their retorts for years because the material refused to transform on a schedule. "Universal validity" is not reassurance; it is recognition that no one has found a shortcut past this particular fire.
