"These mountains are called spiritual mountains in Japan, and they used to be sacred places to which it was thought the spirits of dead human beings went. These spiritual mountains also became the base for the school of mountain ascetics that has existed since the arrival of Buddhism in Japan. According to Japanese folklore, the spirits of the dead remain for a certain time at the mountain to watch over their descendants and to receive memorial services. After being completely purified, the spirit stays within the mountain, but moves to a higher dimension to become one of the ancestral spirits of that village."
