In 1981 Ryuho Okawa began receiving revelations from the spirits of Nikko (1246–1333) and Nichirien (1222–1282), who had been outstanding Buddhist teachers during their lives. Soon he began receiving revelations from Buddha, Jesus Christ, Moses and Confucius as well as spiritual messages from prominent figures such as Socrates, Isaac Newton, Abraham Lincoln, Mahatma Gandhi, Helen Keller and Florence Nightingale. In 1985 he began publishing some of these revelations in Japan. A year later he established the spiritual movement Happy Science (Kofukuno-Kagaku) to help people discover their true potential, to educate them to think and act in a spiritual way and to help create an ideal world on Earth.
