Monk Tanheo prophecy

In the present, according to the principle of the Change progression, Gan dosu(Time of Gan) is reflected in the direction of Gan. According to the principle of Jeongyeok(book of right change or Right-Ching), time of Later Heaven(the world after the change) will start soon because Gandosu(Time of Gan) has come already. The view of the future through the philosophy of Change is much more comprehensive and, furthermore, it gives a big advantage to see the future of human society in the cosmic level.

The end of the world story, the Last Judgement day from Christianity, has been around since two thousand years ago. The origin of this kind of foreknowledge about the future can be found in the Western religion, but according to the Eastern principle of the Change, Bokhui's eight signs of divination revealed 'Principle of Heaven' six thousand years ago and King Wen's eight signs of divination revealed 'Principle of constancy' three thousand years ago and reached until today, and about eighty years ago(in 1886), the principle from the Book of Right Change, the Change of the future, foretold the detailed future of nature and human in Later Heaven.

The prophecy of the Western religion concluded the end of the world and related to the Advent of Christ, but 'the Principle of right Change' resolves the revolution of nature in Later Heaven, how the human race will be judged, and how many people will live in the world without irrationality.

Eight signs of divination in Jeongyeok(Book of right Change) is the Change of future as the eight signs of Later Heaven. According to this, the earth will have a time of maturation as if a girl of puberty encounters the first menstrual period.
