Then, finally, it can become so morbid that it rises to ominous proportions and leads to a tragic sense of persecution. There are persons who come to the point that they are so self-centered that they end up with a persecution complex and the end result is insanity. They end up thinking that the universe stands against them, that everybody is against them. They are turning around within themselves. They are little solar systems within themselves and they can't see beyond that. And as a result of their failure to get out of self, they end up with a persecution complex and sometimes madness and insanity. These are some of the effects of selfcenteredness.
