Coniunctio
Also known as: coniunctio oppositorum, conjunction of opposites, hieros gamos, sacred marriage
The coniunctio — Latin for "conjunction" or "union" — is the supreme symbol of alchemical philosophy and the central image of psychological wholeness in Jungian depth psychology. It denotes the marriage of opposites: sun and moon, king and queen, spirit and body, conscious and unconscious. Jung recognized in this symbol the projected image of individuation itself — the psyche's drive toward integration of what has been split apart.
Why Did Jung Devote His Final Work to This Symbol?
Jung regarded the coniunctio as the deepest mystery in alchemy and in the psyche. He devoted Mysterium Coniunctionis (1955), the magnum opus of his old age, to tracing its symbolism across centuries of alchemical literature. As Edinger observes, Jung “indicated orally that it had still far greater meaning than he was unable to articulate” (Edinger, 1994). The alchemists personified the opposites as Sol and Luna, as red man and white woman, as winged and wingless dragons. Jung demonstrated that these were not chemical fantasies but projections of the psyche’s own structure — the tension between ego and shadow, anima and animus, personal and transpersonal.
“The one-after-another is a bearable prelude to the deeper knowledge of the side-by-side, for this is an incomparably more difficult problem.” — C.G. Jung, Mysterium Coniunctionis (1955)
What Jung means is that experiencing opposites sequentially, now joy, now grief, is tolerable. Holding them simultaneously is the real work. That simultaneity is the coniunctio.
How Does the Coniunctio Relate to Clinical Work?
The psychotherapeutic encounter enacts the coniunctio: one is “thrown back and forth between the opposites almost interminably,” as Edinger writes, until “a new standpoint emerges that allows the opposites to be experienced at the same time” (Edinger, 1985). This new standpoint, both releasing and burdensome, is the lesser or greater coniunctio, depending on the depth of integration achieved. Von Franz noted that the coniunctio appears in modern dreams as the answer to the problem of evil, as a unio mystica with the Self “experienced as a unification of the cosmic opposites” (von Franz, 1993). It manifests first in analysis as the problem of transference and countertransference — the charged field where opposites meet.
