In the case of the saint, the subject, in an unheard-of way, “causes itself”, becomes its own cause. Its cause is no longer decentred, i. e. , the enigma of the Other’s desire no longer has any hold over it. … The status of the subject as such is hysterical: the subject ‘is’ only insofar as it confronts the enigma of “What do you want? ” … By means of the fantasy-formation, the subject provides an answer to the question, ‘What am I for my parents, for their desire? ’ and thus endeavours to arrive at the ‘deeper meaning’ of his or her existence, to discern the Fate involved in it. The reassuring lesson of fantasy is that “I was brought about with a special purpose”. At the end of psychoanalytic treatment, instead of being bothered of what I am for the others, I fully assume the uttermost contingency of my being. The subject becomes ‘cause of itself’ in the sense of no longer looking for a guarantee of his or her existence in another’s desire. http://zizek.livejournal.com/2266.html
