The period from the beginning to the end of Heaven and Earth is called a Cycle of Heaven and Earth and one cycle is 129,600 years. Each cycle is divided into 12 phases of which one phase is 10,800 years. In a cycle, the first six phases belong to "Yang" meaning creation and cultivation. The last six phases belong to "Yin" meaning harvesting and suspension. All matters and beings also follow the order but on a smaller scale, the four seasons which repeat itself; growth is in spring, flourishing in summer, harvesting in autumn and suspension in winter. A human being goes through four stages; infancy, adolescence, adulthood and old age. It can also be called the progression and regression cycle of life.

In the growth phases, God called on seven Buddhas to govern the world so the growth would be orderly. In the regression phases, God called on three Buddhas to amass the souls so that the returning of souls and the essence of everything are orderly.

In the last 5,000 years, it has three periods called the Green, Red and White Periods and three Buddhas. The Green Period was ruled by Ran-deng Buddha which began around 3043BC for 1816 years. At that time there were nine worldwide catastrophes and they were all floods called the "Long-han Flood". The Red Period was ruled by Sakyamuni Buddha which began around the time of King Wen of Zhou Dynasty year 1227BC for 3140 years. At that time there were eighteen fire catastrophes in the form of wars and battles called the "Zhi-ming Fire". The third Period is called the "White Period" and is ruled by Mi-Le Buddha about a hundred years ago which occurs at the transition from the Red Period to the White Period and will last for 10,800 years. According to the collective sins and debts human beings carry, God descends eighty-one catastrophes. The eighty-first catastrophe is the catastrophe of "Gang-feng" (a wind-like catastrophe). This Killer Wind Catastrophe is just like explosions of nuclear bombs; after a big bang, everything within its range will be anihilated. It is the last catastrophe of the Third Period and never seen before by man.

Why is the last catastrophe so destructive? The technology and civilization of mankind have reached the peak. People have disregarded the Truth and moralities. The human mind is so deteriorated that most people are driven by desires. Debts and sins mankind collected have never been so much before, therefore the magnitudes of catastrophes and destructions will be much greater than before. The last catastrophe will lead to the total destruction of the human civilization and technology. It is also the time for all righteous souls to go back to God's Kingdom. It is described as the "Final Judgement" in the Bible according to Tao of Heaven.

White Sun signifies the beginning of the end of the age, meaning the beginning of the end of one cycle of Heaven and Earth and it will appear before year 2000 according to Tao of Heaven. The author saw it twice, in 1994 and 1997 and each time it was like a huge giant white balloon in the early morning sky without glaring for a few seconds. At this time Mi-Le Buddha (Maitreya Buddha) is given the mission of ruling Heaven and Earth and to save the righteous souls back to Heaven. Together with him, JiGong Buddha, Yue-Hui Buddha, Goddess of Mercy and many other Buddhas, Saints, Bodhisattvas are ordered to help in attaining the mission of Mi-Le Buddha in the salvation of mankind. In addition, all deities are also ordered to descend to the world to help this Holy Mission. They will teach people to repent and reform themselves so that people will do good deeds and the magnitudes of the catastrophes will be reduced.
