Must we add that the lamentable exclusiveness that prevails in many Christian churches, is not based upon Scriptural teachings, but upon a wrong metaphysics? All the essential moral truths of Christianity, especially the principle of a universal love, of the eradication of hatred, are in our opinion deeply rooted in the nature of things, and do not, as is often assumed, stand in contradiction to the cosmic order of the world. Further, some doctrines of the constitution of existence have been formulated by the church in certain symbols, and since these symbols contain contradictions and come in conflict with science, the educated classes are estranged from religion. Now, Buddhism is a religion which knows of no supernatural revelation, and proclaims doctrines that require no other argument than the "come and see." The Buddha bases his religion solely upon man's knowledge of the nature of things, upon provable truth. Thus, we trust that a comparison of Christianity with Buddhism will be a great help to distinguish in both religions the essential from the accidental, the eternal from the transient, the truth from the allegory in which it has found its symbolic expression. We are anxious to press the necessity of discriminating between the symbol and its meaning, between dogma and religion, between metaphysical theories and statements of fact, between man-made formulas and eternal truth. And this is the spirit in which we offer this book to the public, cherishing the hope that it will help to develop in Christianity not less than in Buddhism the cosmic religion of truth.
