Life is very difficult and we owe it to our fellow human beings to be as cheerful as we can.

I think the attractiveness of Buddhism is that it doesn't involve a belief in God. That appeals to a lot of people - intellectuals and well-educated people in particular.

One of the effects of religions getting together is that they borrow from one another. An example is the growing number of Catholics who are practicing Yoga and meditation techniques borrowed from Buddhism and Hinduism. So there are these borrowings which I think fertilize the religions.

Buddhism and Christianity are incompatible because there is no God in Buddhism - particularly in Theravada Buddhism. But they are also allies because their values and practices are compatible and they can work together - indeed, they would benefit greatly from doing so.

I think the Buddhist ethic is clearer and more systematic in some ways. The Buddhist notion is that our chief problems are greed, hatred and delusion. Well, delusion is not much mentioned in the Christian tradition. In the West, we have underplayed the idea that our moral and spiritual troubles have to do with a lack of clarity or insight because original sin has dominated so much of our thinking. We tend to think that our troubles are caused by insufficient will power.

Syncretism can be disturbing to people. They have often been taught, "You have to have solid faith and must be sure of your religion," and so on. They fear that they might be threatened by these new developments and mergings. So you get a backlash against it.

I've often admired the way many Catholics who have left the priesthood, for example, have nevertheless remained sincere Catholics. They voted with their feet.
