The wisdom of hexagram transmission

The "Xu Gua Zhuan" explains the arrangement logic of the sixty-four hexagrams: every two hexagrams are a pair, either comprehensive or incorrect, reflecting the inherent laws of the development of things. From the creation of heaven and earth in the universe, to the eventual restoration of both ends, a complete cosmic cycle is formed.

Zhu Xi's hexagram preface song

Qiankun Tunmeng needs a lawyer, who is more skilled than a small animal,
The same person is humble and follows, and the Gu is watching and devouring the Ke Ben,
Peel back the wild and unrestrained appetite, and be prepared to overcome obstacles for thirty days.
Xian Heng fled to Xi and Da Zhuang, in front of the families of Jin and Ming Yi,
Extracting profits and losses, lifting up difficulties, and making progress,
Gen gradually returned to Meifeng and traveled to Xun, and arrived at Zhongfu in the midst of chaos and chaos,
The minor transgression of both Ji and Wu Ji is referred to as the 34th chapter of the lower sutra.
