The religions of the East are not religions in the same sense as Christianity, so comparison between them is difficult, if indeed it is legitimate. Each, again, is highly complex, so that our attempts to define it never do justice to it. Challenged as they are by one another, let each use the knowledge he has of the others to enable him to understand his own religion better, to penetrate beyond the adventitious to the essential. In the relation between the religions, conflict is inescapable. If they sometimes agree, they also often differ, and there are occasions when they seem irreconcilably opposed. But the situation is even more complex than it has been presented hitherto. The presupposition of communication is that, here and elsewhere, no one party to the debate has a monopoly of the truth. All that can be done at present is to call for this boundless communication.
