Enantiodromea
C.G Jung
"He may not know it, but he behaves as if his own individual life, were god's own special will which must be fulfilled at all costs. this is the source of his egoism which is one of the most tangible evils of the neurotics state. If I wish to affect a change in such a person, I am forced to acknowledge the deep significance of their egoism. I should be blind indeed if I did not recognise it as a true will of god. I must even help the person to prevail in his egoism, if he succeeds in this he estranges himself to other people, he drives them away and they come to themselves as they should. For they were seeking to rob him of his sacred egoism.
This must be left of him, for it his strongest and healthiest power. It is a true will of god, which sometimes drives him into complete isolation. However retched this state may be it also stands him in good stead. For in this way alone can he get to know himself and learn what an invaluable treasure is the love of his fellow beings, It is only in the sense of complete abandonment and loneliness that we experience the helpful powers of our own natures.
When one has several times seen this development at work, one can no longer deny that what was evil has turned to good and that what seemed good has kept alive the forces of ego. The arch demon of egoism, leads us along the royal road to that ingathering which religious experience demands. Enantiodromia or conversion into the opposite. And it is this that makes possible the reunion of the warring halves of the personality and therefore brings the civil war to an end"
