Few pastimes are more delightful than tossing pebbles into some still, dark pool, and watching the ripples that rise responsive, as they run in ever widening circles to the shore. Most of us have felt its fascination second only to that of the dotted spiral of the skipping-stone, a fascination not outgrown with years. There is something singularly attractive in the subtle force that for a moment sways each particle only to pass on to the next, a motion mysterious in its immateriality. Some such pleasure must be theirs who have thrown their thoughts into the hearts of men, and seen them spread in waves of feeling, whose sphere time widens through the world. For like the mobile water is the mind of man,--quick to catch emotions, quick to transmit them. Of all waves of feeling, this is not the least true of religious ones, that, starting from their birthplace, pass out to stir others, who have but humanity in common with those who professed them first. Like the ripples in the pool, they leave their initial converts to sink back again into comparative quiescence, as they advance to throw into sudden tremors hordes of outer barbarians. In both of the great religions in question this wave propagation has been most marked, only the direction it took differed. Christianity went westward; Buddhism travelled east. Proselytes in Asia Minor, Greece, and Italy find counterparts in Eastern India, Burmah, and Thibet. Eventually the taught surpassed their teachers both in zeal and numbers. Jerusalem and Benares at last gave place to Rome and Lassa as sacerdotal centres. Still the movement journeyed on. Popes and Lhamas remained where their predecessors had founded sees, but the tide of belief surged past them in its irresistible advance. Farther yet from where each faith began are to be found to-day the greater part of its adherents. The home that the Western hemisphere seems to promise to the one, the extreme Orient affords the other. As Roman Catholicism now looks to America for its strength, so Buddhism to-day finds its worshippers chiefly in China and Japan. But though the Japanese may be said to be all Buddhists, Buddhist is by no means all that they are. At the time of their adoption of the great Indian faith, the Japanese were already in possession of a system of superstition which has held its own to this day. In fact, as the state religion of the land, it has just experienced a revival, a regalvanizing of its old-time energy, at the hands of some of the native archaeologists. Its sacred mirror, held up to Nature, has been burnished anew. Formerly this body of belief was the national faith, the Mikado, the direct descendant of the early gods, being its head on earth. His reinstatement to temporal power formed a very fitting first step toward reinvesting the cult with its former prestige; a curious instance, indeed, of a religious revival due to archaeological, not to religious zeal.
