The Origin and Development of Nine Poems

According to Yun Qi and Zuo Qi's "Seven Numbers", volume 91, the nine principles are harmony, spirit, qi, benevolence, simplicity, clumsiness, clearness, surplus and weakness. Taoism believes that by practicing the nine precepts, one can reach the realm of "real people" of "sexual harmony". "Just like wandering outside the dust, you can have a carefree career, be skilled in machinery, be careful inside, be faithful to what you see, be focused on what you do, stay away from one, and be ignorant of what you do." It remains to be seen, but the outline is drawn, empty and quiet, with life and death as one, with all differences as one side, with precision as the industry, with God as the industry, keeping great simplicity and standing in essence. "That's it," in a purely simple way. "

There is no "nine guards" in Tao Te Ching, but there are seven "guards". For example, "I would rather keep the middle way than say much" (Chapter 5), "Be empty, be quiet and believe" (Chapter 16) and "Tao is often nameless and simple. Small as it is, there is nothing in the world. If Hou can keep it, everything is self-sufficient "(Chapter 32)" Tao often does nothing. If the prince of Hou can keep it, everything will change itself "(Chapter 37) and so on. Keeping the center, keeping the peace, keeping the way and doing nothing all mean keeping the virtual peace and doing nothing and keeping the way.

Xuan Tong Zhen Jing has nine chapters, called Nine Screams, with ten entries and nine divisor series. These ten titles are also different from those in Seven Years Cloud, that is, keeping empty, keeping nothing, keeping flat, keeping easy, keeping clear, keeping true, keeping quiet, abiding by the law, keeping weak and keeping simple.

Although the words are similar, the content and theme of each paragraph are quite different, which reflects the development and changes of Taoist doctrine from early Taoism to Song and Yuan Dynasties.
