In the most primitive concept of religion in Japan was, as the proverb says, "Sawaranu Kami ni Tatari nashi" (If you don't touch the god, the god won't haunt you), people probably only scared and sealed the mausoleums not to bother the divine spirits that were enshrined in the quiet solitude in the depth of the mausoleums.
それ以前の最も原始的な日本人の宗教観は「触らぬ神に祟りなし」のことわざどおり、御室の深奥でひっそりと鎮座する神霊を、機嫌を損ねて廟域から出ないように、ただ畏れて封印するものだったのかもしれない。
