After I left the convent, for 15 years I was worn out with religion, I wanted nothing whatever to do with it. I felt disgusted with it. If I saw someone reading a religious book on a train, I'd think, how awful.

Even before 9/11 I was gripped by a sense of dread: our lack of criticism about what we were doing in the Middle East - the slagging off of a whole religious tradition.

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.

You put yourself in the receptive frame of mind with which we approach music or poetry, which you can measure the difference on a neurological scanner.

Today we often think that before we start living a religious life we have first to accept the creedal doctrines and that before one can have any comprehension of the loyalty and trust of faith, one must first force one's mind to accept a host of incomprehensible doctrines. But this is to put the cart before the horse.

In the holy city of Mecca, violence of any kind was forbidden. From the moment they left home, pilgrims were not permitted to carry weapons, to swat an insect or speak an angry word, a discipline that introduced them to a new way of living.

So, we think about God far to easily and that's because of a lot of social, intellectual, and scientific changes that have taken place in the western world and that has made God very problematic for a lot of people.
