To describe the details of the domestic rite would require much space, - not because they are complicated in themselves, but because they are of a sort unfamiliar to Western experience, and vary according to the sect of the family. But to consider the details will not be necessary: the important matter is to consider the religion and its beliefs in relation to conduct and character. It should be recognized that no religion is more sincere, no faith more touching than this domestic worship, which regards the dead as continuing to form a part of the household life, and needing still the affection and the respect of their children and kindred. Originating in those dim ages when fear was stronger than love, - when the wish to please the ghosts of the departed must have been chiefly inspired by dread of their anger, - the cult at last developed into a religion of affection; and this it yet remains. The belief that the dead need affection, that to neglect them is a cruelty, that their happiness depends upon duty, is a belief that has almost cast out the primitive fear of their displeasure. They are not thought of as dead: they are believed to remain among those who loved them. Unseen they guard the home, and watch over the welfare of its inmates: they hover nightly in the glow of the shrine-lamp; and the stirring of its flame is the motion of them. They dwell mostly within their lettered tablets; - sometimes they can animate a tablet, - change it into the substance of a human body, and return in that body to active life, in order to succour and console. From their shrine they observe and hear what happens in the house; they share the family joys and sorrows; they delight in the voices and the warmth of the life about them. They want affection; but the morning and the evening greetings of the family are enough to make them happy. They require nourishment; but the vapour of food contents them. They are exacting only as regards the daily fulfilment of duty. They were the givers of life, the givers of wealth, the makers and teachers of the present: they represent the past of the race, and all its sacrifices; - whatever the living possess is from them. Yet how little do they require in return! Scarcely more than to be thanked, as the founders and guardians of the home, in simple words like these: - "For aid received, by day and by night, accept, August Ones, our reverential gratitude."...
To forget or neglect them, to treat them with rude indifference, is the proof of an evil heart; to cause them shame by ill-conduct, to disgrace their name by bad actions, is the supreme crime. They represent the moral experience of the race: whosoever denies that experience denies them also, and falls to the level of the beast, or below it. They represent the unwritten law, the traditions of the commune, the duties of all to all: whosoever offends against these, sins against the dead. And, finally, they represent the mystery of the invisible: to Shinto belief, at least, they are gods.
It is to be remembered, of course, that the Japanese word for gods, Kami, does not imply, any more than did the old Latin term, dii-manes, ideas like those which have become associated with the modern notion of divinity. The Japanese term might be more closely rendered by some such expression as "the Superiors," "the Higher Ones"; and it was formerly applied to living rulers as well as to deities and ghosts. But it implies considerably more than the idea of a disembodied spirit; for, according to old Shinto teaching the dead became world-rulers. They were the cause of all natural events, - of winds, rains, and tides, of buddings and ripenings, of growth and decay, of everything desirable or dreadful. They formed a kind of subtler element, - an ancestral aether, - universally extending and unceasingly operating. Their powers, when united for any purpose, were resistless; and in time of national peril they were invoked en masse for aid against the foe .... Thus, to the eyes of faith, behind each family ghost there extended the measureless shadowy power of countless Kami; and the sense of duty to the ancestor was deepened by dim awe of the forces controlling the world, - the whole invisible Vast. To primitive Shinto conception the universe was filled with ghosts; - to later Shinto conception the ghostly condition was not limited by place or time, even in the case of individual spirits. "Although," wrote Hirata, "the home of the spirits is in the Spirit-house, they are equally present wherever they are worshipped, - being gods, and therefore ubiquitous."
The Buddhist dead are not called gods, but Buddhas (Hotoke), - which term, of course, expresses a pious hope, rather than a faith. The belief is that they are only on their way to some higher state of existence; and they should not be invoked or worshipped after the manner of the Shinto gods: prayers should be said FOR them, not, as a rule, TO them.* [*Certain Buddhist rituals prove exceptions to this teaching.] But the vast majority of Japanese Buddhists are also followers of Shinto; and the two faiths, though seemingly incongruous, have long been reconciled in the popular mind. The Buddhist doctrine has therefore modified the ideas attaching to the cult much less deeply than might be supposed.
