After all, what is your personal identity? It is what you really are, your real self. None of us is what he thinks he is, or what other people think he is, still less what his passport says he is. And it is fortunate for most of us that we are mistaken. We do not generally know what is good for us. That is because, in St. Bernard's language, our true personality has been concealed under the 'disguise' of a false self, the ego, whom we tend to worship in place of God.
