A saying ascribed to Prince Shōtoku, the founder of Japanese civilization, compares the three religious and moral systems found in Japan to the root, the stem and branches, and the flowers and fruits of a tree. Shinto is the root embedded in the soil of the people’s character and national traditions; Confucianism is seen in the stem and branches of legal institutions, ethical codes, and educational systems; Buddhism made the flowers of religious sentiment bloom and gave the fruits of spiritual life.
