There are 64 hexagrams in one hexagram in "The Book of Changes".
The ancient scripture "Zhouyi" is divided into two parts, the first part has thirty hexagrams, the second part has thirty-four hexagrams, and the last sixty-four hexagrams, each hexagram has six lines, and the last three hundred Eighty-four lines.
The Bagua symbols overlap each other, forming the sixty-four hexagrams of the Book of Changes, 8×8=64. In order to distinguish the hexagrams of the Bagua and the hexagrams of the sixty-four hexagrams, the ancients called the Bagua "Jing hexagrams". The sixty-four hexagrams are called "bie hexagrams". Therefore, any two hexagrams that overlap can produce a different hexagram. The sixty-four hexagrams are composed of the eight hexagrams. Therefore, judging from the hexagram paintings, a separate hexagram is composed of two classic hexagrams: the lower part is called the inner hexagram (also called the lower body), and the other part is called the outer hexagram (also called the upper body).
Yao Ci, one hexagram and six lines, is composed of six symbols. Each line has a meaning. The diction that expresses this meaning is called Yao Ci. There are six lines in a hexagram, so there are six lines in a hexagram. Under the hexagrams, the six lines have "nine" and "six" as line titles, with the yang line called nine and the yin line called six. A hexagram has six lines from bottom to top. If it is a yang line, it is the ninth day of the lunar month, ninety-two, ninety-three, ninety-four, ninety-five, and the upper nine. If it is a yin line, it is the sixth day of the lunar month, sixty-two, sixty-three, and sixty-four. , six five, six on.
Extended information
The arrangement of the sixty-four hexagrams in "Zhouyi" has an internal basis. According to the ancients, this arrangement reflects the process of creation, development and change of the world. Qian and Kun are the heads, symbolizing that all things in the world begin from the yin and yang of heaven and earth. Qian is yang and is the sky; Kun is yin and is the earth. After Qiankun are Tun and Meng, Tun and Meng symbolize that things have just begun and are in the period of ignorance. ...The last words in the sutra are Kan and Li. Kan is the moon and Li is the sun. They have the meaning of light, symbolizing the vivid manifestation of all things. ?
The lower sutra begins with Xian Heng, which symbolizes the emergence of people, families, and society after the creation of heaven and earth. Refers to the interaction between men and women for marriage. Heng, eternal, refers to the couple growing old together. After the formation of society, it was full of contradictions, and until the end, it was both resolved and unresolved. Jiji means success and completion. Weiji means that things develop endlessly and have no end. The author of "The Book of Changes" strives to make the arrangement of the sixty-four hexagrams in the "Book of Changes" consistent with the evolutionary process of the world.
But this arrangement is not unique. In 1973, the "Book of Changes" written on silk was discovered in the Mawangdui Han Tomb in the eastern suburbs of Changsha City, Hunan Province. Based on the principle of mutual emphasis, the sixty-four hexagrams of the "Book of Changes" are divided into eight groups, called eight palaces, and the sixty-four hexagrams belong to the eight palaces.
