Theologians in all the great faiths have devised all kinds of myths to show that this type of kenosis, of self-emptying, is found in the life of God itself. They do not do this because it sounds edifying, but because this is the way that human nature seems to work. We are most creative and sense other possibilities that transcend our ordinary experience when we leave ourselves behind.

If we try to hold on to our partial glimpses of the divine, we cut it down to our own size and close our minds. Like it or nor, our human experience of anything or anybody is always incomplete: there is usually something that eludes us, some portion of experience that evades our grasp.

Every single one of the major world faiths, whether we're talking about Hinduism, Buddhism, Confucianism, Darwinism, Judaism, Christianity and Islam, have all come to the conclusion that what holds us back from our better self is ego, selfishness, greed, unkindness, hatred. And it all springs from a sense of thwarted ego.

Whatever conclusions we reach about the reality of God, the history of this idea must tell us something important about the human mind and the nature of our aspiration.

Important thing about myth is that it's not just something that you believe, a myth is essentially a program for action. And unless you translate a mythical story, or a doctrine out of the church, into practical action, it just remains incomprehensible. Rather like the rules of a board game which seem very sort of dull and complicated and incomprehensible until you pick up the dice and start to play, when everything falls into place.

I learned a lot from both, initially Jewish and Muslim theologians that had been missing, perhaps from my rather parochial Catholic upbringing.

Illness itself can make you angry, enraged, furious, and it made me angry, enraged, and furious. I don't think it brought me to God at all. It depends how you deal with it. And I think that, at its best, three little words that always have to be applied to religion, religion can help you to deal with that.
