The dialogues are often comical and sprinkled with puns, wordplays and sometimes metafictional jokes that characters in the ancient era refer to or quote from Reikai Monogatari.
Onisaburo stated[6] that this Tale is narrated with plain and simple words so that the ordinary people, instead of intellectuals, would comprehend the God's will.
There are also myths of the histories of various continents and parts of the world corresponding the Ryukyu Islands and Taiwan, and modern-day Iran, India, Sri Lanka, Africa, South America (including Argentina), and Australia.
In summary, Reikai Monogatari tells: All things were created and evolved by the God of Great Origin which spirit has been permeating throughout the universe.
[7] (Onisaburo defined[8] Kan-susanoo-no-ookami as the God of Salvation which has devoted oneself, with the infinite mercy, to save all things both in the Spirit and Present World.)
The doctrine preached in Reikai Monogatari indicates fallacies of existing philosophies, religions and ideologies and denounces the despotism generated from egoism and the oppression and exploitation of a certain race.
[7] Outline of the Reikai Monogatari:[9] The first half of this Volume is an account of the Spirit World which Onisaburo asserted to have witnessed and experienced during seven-days spiritual asceticism.
In 1898, 26-year-old Kisaburo Ueda (Onisaburo's born name) managed to make a living by a small dairy farm founded with his friends in his home village Anao,[10] which is in present-day Kameoka City of Kyoto Prefecture.
Onisaburo stated[11] that since his childhood as the eldest son of an extremely poor farm family, he had held the disgust for the oppression of the strong and the sympathy for the weak.
In August, following an order from the God possessing him, Komatsubayashi-no-mikoto, Kisaburo went to Ayabe, Kyoto and met with Nao Deguchi who was in early sixties at that time.
Before that, as she had shouted the messages against her will, she was regarded as insane by her family members and neighbors and was confined in a latticed space in her own small house.
[18] Shortly after that, Kisaburo and Nao founded a new religious organization called "Kinmei Reigakkai" in Ayabe, which would be developed into Oomoto.
[19] In the early years, in addition to healing the locals' diseases, Kisaburo practiced the ritual by which his trainee was put into a state of the divine possession.
[21] In 1900 and 1901, Kisaburo, Nao, Sumi and selected followers fulfilled the following missions in compliance with the divine demands made through the automatic writings;[22] "The Opening of Oshima and Meshima": Oshima (another name, Kanmurijima) and Meshima (another name, Kutsujima) are uninhabited islets in Wakasa Bay facing the Sea of Japan.
However, due to the ambition and self-conceit, he was possessed by a powerful evil god and turned to be one of the fiercest opponents of Kisaburo.
[26] The divine order by the automatic writing, which was not revealed to most of the followers at that time, was to secretly draw the forbidden sacred water from the river near the Shrine.
[31] Ignoring this obligation, in February 1924 he secretly headed for Mongolia, with some selected disciples including Morihei Ueshiba who later founded the martial art of Aikido.
[32] His wish was to establish a new kingdom in the wilderness and to form a federation of East Asian countries in preparation for the unification of the world by the religion and the construction of Heaven on Earth.
[33] Arriving in Mukden (present-day Shenyang City, China), Onisaburo and his party formed an alliance with Lu Zhankui, the local warlord.
[34] Marching forward bad roads by cars and on horsebacks, Onisaburo healed the sick and the injured and became revered by the locals.
In June he ordered his army to drive the party to Bayisingtu (present-day Tongliao City, Inner Mongolia, China) and executed Lu and his subordinates by shooting.
[39] In 1925 Oomoto founded an organization Jinrui Aizen-Kai (Universala Homana Asocio) which advocates the amity and harmony of all mankind.
[2] Onisaburo dictated most parts of Reikai Monogatari lying on futon (Japanese style mattress), without any reference.
[47] (In 1920 Oomoto had bought up a daily newspaper company and had publicized the prophecy and warning of war, calamity and social reform.
