Compassion is aptly summed up in the Golden Rule, which asks us to look into our own hearts, discover what gives us pain, and then refuse, under any circumstance whatsoever, to inflict that pain on anybody else. Compassion can be defined, therefore, as an attitude of principled, consistent altruism.

It is people who are violent, rather than "religions"; and since we secularised our politics we have had two major world wars, the Holocaust, the Soviet Gulag, and the atomic attacks on Hiroshima and Nagasaki - none of which were inspired by religion. If we want to understand the dangers of our world, we can no longer accept the old received ideas.

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.

Religion is a practical discipline and it's one that we have always done, ever since humanity appeared on the scene when Homo sapiens became Homo sapiens. Sapiens became a human being, our minds very naturally segue into transcendence.

Golden Rule lies at the heart of every religious and of every ethical system of morality, it what makes us look at one another. The religions have all adopted it independently, Chinese, Indian, Muslim, Christian, Jewish, because they find it works and because it says something very deep about the structure of our humanity.

If your child dies, or you witness a terrible natural disaster, yes, you certainly want a scientific explanation as to what's happened. But science can't help you to find meaning, help you deal with that turbulence of your grief, rage, and dismay.

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.
