These phenomena indicate that a repair of the ego-Self axis is occurring. Meetings with the therapist will be experienced as a rejuvenating contact with life which conveys a sense of hope and optimism. At first such effects require frequent contact and wane quickly between sessions. Gradually, however, the inner aspect of the ego-Self axis becomes increasingly prominent, The experience of acceptance not only repairs the ego-Self axis but also reactivates residual ego-Self identity.
— Edward F. Edinger
Edinger is describing something precise here, and it is worth pausing on what makes it so. The repair he names is not a recovery of self-esteem, not a cognitive reframe, not even healing in the ordinary therapeutic sense. It is the restoration of a relation — the ego's living connection to what is larger than itself — and the first sign of that restoration is, characteristically, dependency. The patient needs the therapist frequently; the warmth wanes between sessions; the light does not yet hold overnight. This is not a failure of treatment. It is the accurate signature of where the repair is happening.
What Edinger calls "ego-Self identity" is the early, undifferentiated state before the ego learned it was separate — before the axis became experienced as a relation rather than a given. The reactivation of that identity is not regression; it is the psyche finding its root again, briefly, before the differentiated axis can take on enough life to carry the weight alone. The movement from outer contact to inner axis is the whole of the process. The therapist's acceptance does not give the patient something new. It restores the person's capacity to be fed by what was always there — which had simply gone silent.
