This seems to fit the " transcendent function " aspect we have been discussing and might also be applicable to the " Mandorla or Union of Opposites " you mentioned.
( I came across the first quotes taken from a prior discussion shared in a past PM. Here is the link to the Lexicon itself and the following definition of " transcendent function ". ):
From the " Jungian Lexicon ":
From the term " conflict ":
Serious conflicts, especially those involving love or duty, generally involve a disparity between the functions of thinking and feeling. If one or the other is not a conscious participant in the conflict, it needs to be introduced.
The objection [may be] advanced that many conflicts are intrinsically insoluble. People sometimes take this view because they think only of external solutions-which at bottom are not solutions at all. . . . A real solution comes only from within, and then only because the patient has been brought to a different attitude.["Some Crucial Points in Psychoanalysis," CW 4, par. 606.]
Jung's major contribution to the psychology of conflict was his belief that it had a purpose in terms of the self-regulation of the psyche. If the tension between the opposites can be held in consciousness, then something will happen internally to resolve the conflict. The solution, essentially irrational and unforeseeable, generally appears as a new attitude toward oneself and the outer situation, together with a sense of peace; energy previously locked up in indecision is released and the progression of libido becomes possible. Jung called this the tertium non datur or transcendent function, because what happens transcends the opposites.
Holding the tension between opposites requires patience and a strong ego, otherwise a decision will be made out of desperation. Then the opposite will be constellated even more strongly and the conflict will continue with renewed force.
Jung's basic hypothesis in working with neurotic conflict was that separate personalities in oneself-complexes-were involved. As long as these are not made conscious they are acted out externally, through projection. Conflicts with other people are thus essentially externalizations of an unconscious conflict within oneself.
( Which led me to the term " Ego ": )
Jung pointed out that knowledge of the ego-personality is often confused with self-understanding.
Anyone who has any ego-consciousness at all takes it for granted that he knows himself. But the ego knows only its own contents, not the unconscious and its contents. People measure their self-knowledge by what the average person in their social environment knows of himself, but not by the real psychic facts which are for the most part hidden from them. In this respect the psyche behaves like the body, of whose physiological and anatomical structure the average person knows very little too. ["The Undiscovered Self," CW 10, par. 491.]
In the process of individuation, one of the initial tasks is to differentiate the ego from the complexes in the personal unconscious, particularly the persona, the shadow and anima/animus. A strong ego can relate objectively to these and other contents of the unconscious without identifying with them.
Because the ego experiences itself as the center of the psyche, it is especially difficult to resist identification with the self, to which it owes its existence and to which, in the hierarchy of the psyche, it is subordinate.
The ego stands to the self as the moved to the mover, or as object to subject, because the determining factors which radiate out from the self surround the ego on all sides and are therefore supraordinate to it. The self, like the unconscious, is an a priori existent out of which the ego evolves.["Transformation Symbolism in the Mass," CW 11, par. 391.]
Transcendent function. A psychic function that arises from the tension between consciousness and the unconscious and supports their union. (See also opposites and tertium non datur.)
When there is full parity of the opposites, attested by the ego's absolute participation in both, this necessarily leads to a suspension of the will, for the will can no longer operate when every motive has an equally strong countermotive. Since life cannot tolerate a standstill, a damming up of vital energy results, and this would lead to an insupportable condition did not the tension of opposites produce a new, uniting function that transcends them. This function arises quite naturally from the regression of libido caused by the blockage.[Ibid., par. 824.]
The tendencies of the conscious and the unconscious are the two factors that together make up the transcendent function. It is called "transcendent" because it makes the transition from one attitude to another organically possible.[The Transcendent Function," CW 8, par. 145.]
In a conflict situation, or a state of depression for which there is no apparent reason, the development of the transcendent function depends on becoming aware of unconscious material. This is most readily available in dreams, but because they are so difficult to understand Jung considered the method of active imagination-giving "form" to dreams, fantasies, etc.--to be more useful.
Once the unconscious content has been given form and the meaning of the formulation is understood, the question arises as to how the ego will relate to this position, and how the ego and the unconscious are to come to terms. This is the second and more important stage of the procedure, the bringing together of opposites for the production of a third: the transcendent function. At this stage it is no longer the unconscious that takes the lead, but the ego.[Ibid., par. 181.]
This process requires an ego that can maintain its standpoint in face of the counterposition of the unconscious. Both are of equal value. The confrontation between the two generates a tension charged with energy and creates a living, third essence.
From the activity of the unconscious there now emerges a new content, constellated by thesis and antithesis in equal measure and standing in a compensatory relation to both. It thus forms the middle ground on which the opposites can be united. If, for instance, we conceive the opposition to be sensuality versus spirituality, then the mediatory content born out of the unconscious provides a welcome means of expression for the spiritual thesis, because of its rich spiritual associations, and also for the sensual antithesis, because of its sensuous imagery. The ego, however, torn between thesis and antithesis, finds in the middle ground its own counterpart, its sole and unique means of expression, and it eagerly seizes on this in order to be delivered from its division.["Definitions," CW 6, par. 825.]
The transcendent function is essentially an aspect of the self-regulation of the psyche. It typically manifests symbolically and is experienced as a new attitude toward oneself and life.
If the mediatory product remains intact, it forms the raw material for a process not of dissolution but of construction, in which thesis and antithesis both play their part. In this way it becomes a new content that governs the whole attitude, putting an end to the division and forcing the energy of the opposites into a common channel. The standstill is overcome and life can flow on with renewed power towards new goals.[Ibid., par. 827.]
