According to Records of Japan and Historical Records, the center of Shinto doctrine is the "spirit" and "truth" of God. The communication between God and man is realized through mutual induction. God is the origin of all things, and people believe that by worshipping God, they can respond. "Truth" is an attitude towards life, which advocates honesty and truthfulness and attaches importance to virtues such as loyalty, filial piety, benevolence and faithfulness. The relationship between spirit and truth is that man is the son of God, so human nature is sacred. Special emphasis is placed on the rights of people who respect themselves and others, and individuals have a natural responsibility to the collective. "Comfort spirit" and "comfort spirit" are the main forms of sacrifice in the shrine. Filial piety is the most important ethical principle in Shinto theory system. Filial piety in a broad sense includes filial piety to parents, respect for God and loyalty to the emperor. It advocates that the Japanese nation is the descendant of the gods, and when it rules the world, its national system and throne have supreme dignity. His thought had a great influence on the restoration of Meiji Restoration, and it was also the main theoretical basis of Shinto in modern shrines. Almost every Shinto Sect will put forward "loyalty", loyalty to the country, patriotism and loyalty to the monarch. These are very similar to the "loyalty festival" in the spirit of Bushido. Shinto loyalty has played an important role in the formation of Bushido spirit. Influenced by Shinto in the early days, the privileged ruling class paid attention to the samurai's "loyalty" requirement in the formation process, and gradually became the principle that the samurai adhered to and the spirit of Bushido.
