The simplified version of "The Preface to the Yellow Emperor's Internal Classics":
Those who release their bondage and get rid of difficulties, guide their qi completely, save Li Yuan in Renshou, and help those who are disadvantaged and gain peace, If it is not the Three Holy Paths, it cannot be achieved. Kong Anguo's preface to "Shangshu" says: "The books written by Fuxi, Shennong and Huangdi are called the Three Tombs, which are the great road." Ban Gu's "Hanshu·Yiwenzhi" says: "The "Huangdi Neijing" is in eighteen volumes." "Suwen" The nine volumes of the Jingqi Jing are also counted together with the nine volumes of the Lingshu. Although the teachings have been changed over the years, the teachings still remain. I am afraid that it is not the person who is the one, and sometimes I hide it, so the seventh volume is hidden by the master. Today, there are only eight volumes. However, its writing is simple, its meaning is profound, its reasoning is profound, and its interest is profound. The signs of heaven and earth are divided, the yin and yang are arranged in sequence, the changes are expressed, and the signs of death and life are obvious. If you don't plan for it, you will be far away from each other; if you don't make an appointment, you will be secluded and understanding. Judging from his words, there are signs, and the things he has tested are not true. Sincerity can be said to be the sect of the supreme Tao, and it is the beginning of devotion to life.
If heaven’s secrets emerge quickly, wonderful knowledge and profound knowledge will be revealed. Although Jiang Mou is based on the knowledge of life, and the standards are also qualified for exegesis, there is no such thing as being unable to travel by a short distance or leaving a house. However, if you deliberately study the essence, explore the hidden details, or recognize the true essence of the contract, your eyes will be incomplete. Therefore, if you move, you will achieve success. It is like ghosts and gods praising you, and appointing extraordinary heroes in the world, and it will appear from time to time. Then there was Duke Qin in Zhou Dynasty, Duke Chunyu in Han Dynasty, Duke Zhang and Duke Hua in Wei, all of whom had achieved this wonderful way. Xianri uses it in new ways, and it helps steam people. The flowers and leaves are glorious, and the sound and reality match each other. The writing of the teachings is also a lie from heaven.
Bing is weak and advocating for Taoism, and he has devoted himself to health care. Fortunately, I encountered the True Sutra, which was shaped like a turtle mirror. However, the book is erroneous, the chapters are heavy, inconsistent, and the meaning of the text is unclear. It is not easy to implement, and it is also difficult to implement it. The passage of time has brought disaster. Maybe one article appears again, but with two separate names; some two treatises are swallowed up together, and they are both included in one title; some questions and answers are not finished, and there are separate titles for each chapter; or there is no writing at all, and it is said to be in the world. Emphasis on "Jinghe" and crown "Acupuncture", combine "Prescription and Yi" to become "Cough Chapter"; separate "Xu Shi" to become "Bi Cong", combine "Meridians" to become "Lun Yao"; section "Pibu" " is "meridians", "Zhi Tiao" is retired and "Acupuncture" is first. There are countless flows like this. And when he is about to be promoted to Daiyue, why should he be ridiculed? If you want to reach Fusang, you can't do it without a boat. He is diligent in visiting, and he has his own person. After twelve years, Fang Zhen understood the essentials, inquired about gains and losses, and realized his long-cherished intentions. At that time, in Guo Zizhai Hall, I received the secret copy of my late master Zhang Gong. The writing was clear and the meaning was comprehensive. After reading it in detail, all doubts were resolved. I was afraid that I would be lost in the late school and lose my talent as a teacher, so I wrote annotations and passed them down to immortality. Together with the old collection of volumes, 81 chapters and 24 volumes are combined into one volume. It is hoped that the end will be clear and the first will be clear, the Sutra will be sought and annotated, the child's ignorance will be developed, and the best principles will be preached.
For those that are simplified and broken, and whose meanings are not connected, search all scriptures and treatises and move them to fill in their places; for those that are missing in the text and refer to things that are unclear, measure their meaning and add words to clarify their meanings. ; The chapters are swallowed up, and the meanings are not related. If the names are missing, distinguish the categories of things, and put them at the beginning of the chapter. If the emperor and his ministers ask questions, if the etiquette is not good, they should test the school's dignity and add more to make the meaning clear. If there are mistakes in the slips and fragments of the text, and there is overlap between the front and back, we should detail the meaning and cut off the complexity to preserve the essence; if the secrets of rhetoric are difficult to discuss in a rough way, write a separate "Xuanzhu" to explain the way. All the characters added are written in Zhu, so that the present and the past can be clearly divided, and the characters are not mixed and mixed. The concubines make the imperial edict clear and express the mysterious words smoothly, just like the towers hanging high, the Kui Zhang is not chaotic, the deep springs are pure and silky, and the scales are salty. There is no time for monarchs and ministers to die prematurely, and Yixia has the hope of prolonging their lives. Let the workers and disciples not make mistakes, the scholars only know clearly, the Tao is popular, and the Huiyin is numerous. After thousands of years, we will know that the great sage's kindness is endless.
At that time, the first year of Baoying's reign in the Tang Dynasty was in the order of Renyin.
