Can anyone describe Korea's indigenous religion, Tendoism?

When the Joseon Dynasty was under the threat of Western influence in the 1860s, Choi Je-woo, fearing that the traditional Korean religion would be replaced by Catholicism, synthesized the important elements of the traditional religion and founded the Cheon Do religion, which was then called "Eastern Learning" in contrast to "Western Learning. At that time, it was called "Donghak" in contrast to "Western learning," and in 1905 it was changed to "Cheondoism" by Sun Byung-hee (1861-1922), the third head of the religion. "In 1905, Sun Byung-hee (186l-1922), the third head of the religion, changed the name of Donghak to Tendoism (which is the same as Catholicism), and said, "The ethics of Confucianism, the awareness of Buddhism, and the nurturing of qi by the Immortals are the natural endowment of human nature and an inherent part of the Way of Heaven, and the Way of Heaven is the infinite source of the Way of Heaven. Tendoism, as a unique Korean religion, believes in Jegojin and emphasizes the unification of the believer and the god (Tendoism is based on the principle that man and the god of Tendoism are the same, but man is not the god of Tendoism, and that man keeps the god of Tendoism in his heart as the source of his dignity, and that he can become one with the god by practicing it). It also basically believes in "healing, righteousness and rituals". There are 280 churches in the country with about 1.13 million believers, and 200,000 believers in 21 churches in Seoul.

Among the democratic political parties in the Democratic People's Republic of Korea is the Chondoist Young Friends Party, which is composed mainly of peasants who believe in Chondoism.
