Huangdi was in the Mingtang (Hall of Enlightenment), with Leigong attending him. Huangdi said, "You have mastered numerous medical texts and engaged in extensive medical practice. Please discuss your understanding of success and failure in diagnosis and treatment, specifically why some cases succeed and others fail."
Leigong replied, "I studied under a master following the meridian theories, and he stated that I achieved perfect results in all cases. However, errors sometimes occur in practice. May I ask for an explanation of these incidents?"
Huangdi asked, "Is it because you are young and your wisdom is not yet fully developed? Or do you mix various disparate methods? The twelve meridians (Twelve Primary Meridians) and three hundred and sixty-five collaterals (Collateral Vessels) are well-known to people and should be followed by physicians. The reason for failing to achieve perfection lies in a lack of spiritual focus, disordered will, and a disconnect between the internal body and external environment, leading to frequent doubt and danger. Failing to understand the principles of Yin-Yang (Yin and Yang) and their reversal or compliance constitutes the first error in treatment. Abandoning studies before completing them, recklessly employing miscellaneous techniques, falsely claiming them as orthodox Dao (The Way), changing names to boast of one's own merit, and rashly using Bian stones (Bian Shi, stone tools for surgical massage) thereby bringing blame upon oneself constitutes the second error. Failing to adapt to the living conditions of patients based on their poverty or nobility, ignoring the dampness or dryness of their dwellings, their constitutional cold or heat, and the appropriateness of their diet; failing to distinguish between courage and timidity in individuals; and lacking the ability to use comparative analysis (Bi Lei) leads to self-confusion rather than clarity, constituting the third error. When diagnosing disease without asking about its onset—such as emotional distress from worry and grief, dietary irregularities, excessive lifestyle habits, or exposure to toxins—and then hastily palpating the Cun Kou (Cun Kou pulse point at the radial artery) without addressing these factors, how can one accurately identify the disease? Rashly naming diseases and being misled by superficial appearances constitutes the fourth error. Therefore, worldly discussions often stray far from reality, lacking precise diagnostic standards, and diagnoses neglect human and social factors. The path of mastering medical arts requires composure and preservation. If one merely sits and relies solely on palpating the Cun Kou pulse, failing to align with the five pulses (Five Zang Pulses) and the origins of myriad diseases, one may initially blame oneself but later attribute fault to one's teacher. Thus, treatment that does not follow rational principles abandons medical art to the marketplace; random treatments occasionally succeed, leading the foolish mind to feel self-satisfied. Alas! The Dao is profound and obscure; who truly knows it? The great Dao resembles Heaven and Earth and matches the Four Seas. If you do not understand the teachings of the Dao, accepting them only turns enlightenment into obscurity."
