A patient doesn't select his physical ailments. They happen to him. You could just as well ask when you are eaten by a crocodile, 'How did you select that crocodile?'. Nonsense. He has selected you. The patient doesn't even select the symptoms unconsciously. That is an extraordinary exaggeration of the subject to say he was choosing such things. They get him.
Carl JungThe sad truth is that man's real life consists of a complex of inexorable opposites - day and night, birth and death, happiness and misery, good and evil. We are not even sure that one will prevail against the other, that good will overcome evil, or joy defeat pain. Life is a battleground. It always has been and always will be; and if it were not so, existence would come to an end.
Carl Jung
