Why do you say "Gankun" is the gate of Zhouyi?

The copulative biography of Yi Zhuan quoted Confucius' exposition and put forward the view that Gankun is the door to change: "Confucius said,' Gankun, is the door to change evil?' Dry, penis also; Kun, the matter of yin is also. Yin and yang combine virtue, rigid and soft, written by the body of heaven and earth, and communicate the virtue of the gods. "This shows that the two hexagrams of Gankun have different common positions in Zhouyi.

In form and meaning, the two hexagrams of Gankun are the "parents" who generate other hexagrams. In the general book, Gan Gua and Kun Gua are listed before each hexagram. Gankun itself is like entering the door of Zhouyi. But it's not just because they're ahead. A hexagram consists of upper and lower meridians. Once three hexagrams, two hexagrams and six hexagrams. These six symbols are nothing more than yin and yang. Therefore, the sixty-two hexagrams after Gankun can be regarded as one or more yang hexagrams of Gankun exchanged with several yin hexagrams of Gankun. This is a formality.

In a sense, the change of Yin and Yang between Gan and Kun produces other hexagrams instead of simple deformation, which is the basic principle of Yi Dao. Each chapter of Yi Zhuan explains these two hexagrams more than other hexagrams, and there is an article in Classical Chinese Zhuan that specifically explains the meaning of Gan Kun and his hexagrams. In Yi Zhuan Jie Zhuan, the origin, nature, status and application of Gan Gua and Kun Gua are discussed. "Heaven is humble, and Gan Kun is determined." -This is the cause of Gan Kun. Gan Kun follows the example of heaven and earth, doing above, being respectful, being below, being humble. It turns out that Gankun is a divination of heaven and earth.

"Dry Kun into a man, Kun Tao into a woman. Knowing its beginning, Kun made it. " "The imaging is dry, just like Kun."

"Dry, its static also designed, its move is straight, is a birthday. Fu Kun, his quietness is also quiet, and his movements are also open, which is based on a wide range of knowledge. "

"Therefore, the household is called Kun, the account opening is called dry, the door opening is called change, the communication is called communication, the image is called, the shape is called the device, the method is used, and the access and the people's salt are used."

-The above are the respective attributes of Gankun Gua. Gankun is the master and the movement, and Kunkun is the slave and the static, one master and one slave, and one movement and one static, so that everything becomes one.
