We all wonder how our ancestors were so wise, and in ancient times, there was no advanced civilization, how they came up with so many clever things at once, such as the I Ching.
The I Ching talks about the most about heaven, earth, and man. Heaven and earth are nature. Then what man does is naturally to conform to nature, not to force a change in nature.
Speaking of heaven, earth, and man, it is easy to understand that of all things in the world, only man is the greatest being.
However, as human beings, under the guidance of the I Ching, we have cooperated with nature without incident for more than 5,000 years. There is no major destruction and pollution, and it has been living in an environment of green mountains and green waters, but nearly 200 years of dead damage have caused people and animals to be uneasy.
Man was originally the spirit of all things, but now he has become the scourge of all things, destroying the harmonious state of unity between heaven and man.
With the development of scientific and technological civilization, people's material life is good, but the environment is destroyed, and the space for future generations to continue to develop is short. The state of unity between heaven and man advocated by the I Ching has also been destroyed.
