What are the three changes of the Book of Changes?

First, it is easy to connect mountains.

Kong Yun: Lianshan started in Shennong. Shao Yong said: Xiayi said that mountains are connected. According to Fu Xichao, he passed it on to the 19th Emperor and went to Shennong. Shennong, surnamed Jiang, originated in Lieshan, namely Suixian County, Hubei Province, and is now in Tongbai Mountain area, so it is also called or.

At that time, human activities had changed from fishing and hunting to farming, and Shennong invented wood for planting and production; I also tasted a hundred herbs as medicine, opened the market to facilitate trade, benefited the people, and had ample food and clothing. Following the enlightenment of the sages, this paper expounds the Yi-ology, and the hexagrams used are mainly hexagrams, which cover the ups and downs of mountains. Clouds come from mountains, so clouds are easy to connect mountains.

Second, it is easy to go back to Tibet.

Du Zichun says: The Yellow Emperor is in Tibet. The name of the Yellow Emperor originated from the loess and was born in the field of Xuanyuan, which is now Xinzheng County, Henan Province. The Yellow Emperor, also known as Xuanyuan or Xiongshi, took soil as the king. The Yellow Emperor invented clothes, boats, bows and arrows, Chu Jiu and compasses, and created Jia Zi, Jin Lu, arithmetic, writing and calligraphy. Therefore, China culture belongs to the earth, taking Xiang Kun as the land, for the earth and for the use, that is, the noumenon of all things, so it is easy to return to Tibet.

Third, Zhouyi.

There are two theories about the name of Zhouyi: First, Zheng Xuan called Yi Dao Zhoupu, which is all-encompassing and repeated, and it is also reasonable. Second, Confucius said: "The common name and proper name of Yi for foreigners are based on the function of Yi, since the opening of heaven and earth, the luck of Yin and Yang, the change of cold and heat, and the turn of the sun and the moon.

King Wen is a divination, Duke Zhou is a eulogy, and it is the Zhou Dynasty, hence the name Zhouyi. "Scholars, more after adopting this statement. The Book of Changes, with the five hexagrams of Gambi and Kun as the head, is open and closed by Gankun, and yin and yang are combined, indicating that it is born and changed with the virtue of nature. King Wen showed that it was easy to be poor and changeable, studied the good and the bad, and hoped to meet people with weather, create inventions and save the people.

Extended data:

No matter how the outside world changes, people's initial heart cannot be changed. At the beginning of life, human nature is good, and goodness, as the most primitive nature of human beings, must be maintained. Only by keeping a constant mind can you know what is feasible and what is not, and you are a principled person. The initial heart of human beings is the beginning of the innate kindness, sincerity, innocence, enterprising, tolerance and love of life. Only by keeping this unchanging heart can we go further in the ever-changing world!

Changes and difficulties are actually relative, and everything is relative. Being stingy is different, it's a cycle. When you are lucky, you become stingy, and disaster will follow. After being tempered by disaster, you repented and got well again. At the same time, when a person is lonely and dangerous, if he knows how to reflect on himself and think about change at the end of the road, then he can also get good luck through hard work.
