[Buddhism and Christianity] are in one sense parallel and equal; as a mound and a hollow, as a valley and a hill. There is a sense in which that sublime despair is the only alternative to that divine audacity. It is even true that the truly spiritual and intellectual man sees it as sort of dilemma; a very hard and terrible choice. There is little else on earth that can compare with these for completeness. And he who does not climb the mountain of Christ does indeed fall into the abyss of Buddha.
