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

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.

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 would like to see an agreement that recognizes that we live on the same planet and that some interests, such as human rights, must be universal and that all religions must be respected.

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.

I don't think religions will merge into a great global faith. But I do believe we're moving toward a global ideology that has a place for religion and recognizes the contributions of the different traditions. Hopefully, it will have an overarching view as to how we can work together for the promotion of human values and spirituality.

If you were going to be attracted to a mystical faith which involved the contemplative life, Buddhism would be quite reasonable. But then, not everybody is a budding mystic. In fact, it's pretty certain that very few people are. So another kind of religion, one that was perhaps more pragmatic and service-oriented, might appeal to those others. So I think you have to take your values into account.
