It is the moral task of alchemy to bring the feminine, maternal background of the masculine psyche, seething with passions, into harmony with the principle of the spirit-truly a labour of Hercules! In Dorn's words: Learn therefore, O Mind, to practise sympathetic love in regard to thine own body, by restraining its vain appetites, that it may be apt with thee in all things. To this end I shall labour, that it may drink with thee from the fountain of strength,233 and, when the two are made one, that ye find peace in their Jungian. Draw nigh, O Body, to this fountain, that with thy Mind thou mayest drink to satiety and hereafter thirst no more after vanities. O wondrous efficacy of this fount, which maketh one of two, and peace between enemies! The fount of love can make mind out of spirit and soul, but this maketh one man of mind and body.
— Carl Gustav Jung
Dorn's fountain is doing something specific that the pneumatic tradition almost never permits: it runs downward, toward the body, not away from it. Every other fountain in the Western inheritance — Ficino's solar fountain, the Neoplatonists' emanation, even much of Jung's later language about the Self — flows from above and draws the soul up. This one draws the mind down to drink with the body, and the peace promised is not transcendence but the peace of enemies who have stopped fighting. That is a structurally different outcome.
What makes the passage hard to sit with is that it frames body-hunger as vain appetite to be restrained, and yet restraint is not the telos — union is. The ascetic grammar is in service of something the ascetic tradition never actually wanted: a body that remains present in the wholeness, not sublimated out of it. Dorn's "one man of mind and body" is not a spiritualized body; it is a body that has been met. The alchemical insistence on matter — sulfur, salt, the *corpus* as genuine third — keeps catching on precisely this hook: that any framework promising relief from the body's claims is offering a solution to the wrong problem. The fountain does not eliminate thirst. It changes what you are thirsty for.
