The most courageous thing we will ever do is to bear humbly the mystery of our own reality.
You cannot be naïve about evil. You cannot be naïve to the reality that there are human beings and human situations which have totally identified with the dark side of reality. They are malicious. Realism teaches you to put up appropriate boundaries so that people can't do any more evil than possible. But that doesn't mean you do evil back to them.
I have committed myself to joy. I have come to realize that those who make space for joy, those who prefer nothing to joy, those who desire the utter reality, will most assuredly have it. We must not be afraid to announce it to refugees, slum dwellers, saddened prisoners, angry prophets. Now and then we must even announce it to ourselves. In this prison of now, in this cynical and sophisticated age, someone must believe in joy.
You create your response to reality, and that response, for all practical purposes, is your reality.
