Central to the faith is the belief in
Haneullim, the triad of Gods of Korean culture: the creator (Hanim/
Hwanin), the teacher (Hanung/
Hwanung) and the ruler (Dangun/Hanbaegŏm). Dangun, the leader of the Korean nation, is thought to be the third, and human, manifestation of Haneullim ("God of Heaven") or Haneul ("Heaven"). After his earthly reign, Dangun ascended to Heaven. The faith is embodied in three sacred texts. Believers claim that they date back to the time of Dangun, or even earlier, and this claim, although disputed by scholars, is also accepted by many Koreans who do not belong to Daejongism. The three texts are the ''Ch'ónbugong
(The Classic of the Seal of Heaven), a narrative of the origins of the world, the Samil sin'go
(The Teachings of the Triune God), a theological statement, and the Ch'amjóngyóng'' (The Classic of the Wise One), a manual of ethics. A number of scholars believe that these books were compiled in the first two decades of the 20th century, based on visions and revelation the founder of Daejongism, Na Cheol (1863–1916), claimed to have received. Daejongism is also well known for its teaching of breathing techniques, known in the West as part of the so-called internal alchemy (
Neidan in
Taoism). Daejongism's techniques focus on the '"sea of energy," which is also often referred to as the cinnabar field or the elixir field (
tanjón).The
tanjon is a field rich in the vital energy
Qi and the religion offers techniques to draw on this field and circulate the energy through the human body. These techniques became extremely popular in the 1970s and generated a new interest in Daejongism and its school of internal alchemy, known as Kich'ónmun. ==Samsin Sinang==
