Psychology and Alchemy (Collected Works of C.G. Jung Vol.12)

As a doctor it is my task to help the patient to cope with life.

I cannot presume to pass judgment on his final decisions, because I know from experience that all coercion-be it suggestion, insinuation, or any other method of persuasion-ultimately proves to be nothing but an obstacle to the highest and most decisive experience of all, which is to be alone with his own self, or whatever else one chooses to call the objectivity of the psyche.

The patient must be alone if he is to find out what it is that supports him when he can no longer support himself.

Only this experience can give him an indestructible foundation. ~Psychology and Alchemy (1944) CW 12: P.32
