Religion is not about accepting twenty impossible propositions before breakfast, but about doing things that change you. It is a moral aesthetic, an ethical alchemy. If you behave in a certain way, you will be transformed. The myths and laws of religion are not true because they they conform to some metaphysical, scientific or historical reality but because they are life enhancing. They tell you how human nature functions, but you will not discover their truth unless you apply these myths and doctrines to your own life and put them into practice.

From the Muslims I learned from the extraordinary pluralism of the Koran, the fact that the Koran endorses every single one of the major world faiths, but I was particularly enthralled by the Sufi tradition, the mystical tradition of Islam, which is so open to other religious faiths.

Mythology and science both extend the scope of human beings. Like science and technology, mythology, as we shall see, is not about opting out of this world, but about enabling us to live more intensely within it.

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.

I have become convinced, through my studies, that the only way to achieve a safe, just and viable world is to live by the Golden Rule. This is what drives my writing. I want to point out this interconnectedness, point out the beauty of the faith in all traditions without exception, show the complexity of the atrocities that we have experienced, and our shared culpability as a species.

It's quite common for a Sufi mystic to cry in ecstasy that he's neither a Jew, a Christian, nor a Muslim. He is at home equally in a synagogue, a mosque, a temple, or a church because when one's glimpsed the divine, one's left these man-made distinctions behind.

You know how it is in the symphony when you are listening to the symphony, the last notes die away, and there's often a beat of silence in the auditorium before the applause begins. It's a very full and pregnant silence. Now theology should bring us to live into that silence, into that pregnant pause.
