Capítulo 42 de 81
黄帝内经·灵枢
Overall Paraphrase
The Yellow Emperor said: I have learned from you, Master, the methods of the Nine Needles (the collective term for nine ancient types of acupuncture needles), and I have also privately read various medical texts. The methods recorded in these texts are diverse—some use Daoyin breathing exercises (regulating qi and blood through body movements and breath control), some use massage, moxibustion, hot compression (applying warm objects to the body surface), acupuncture, cauterization (burning with fire), and others use decoctions for oral administration. Now, should one adhere to only one of these methods, or should one master and practice them all?
Qi Bo replied: These techniques are methods intended for the many different kinds of people in the world; no single person can master them all completely.
The Yellow Emperor said: This is what is meant by the saying, "Hold fast to the root and do not lose it, and you will penetrate the essence of all things." Now I have heard from you the essentials of Yin and Yang, the mechanisms of deficiency and excess, the errors of qi and blood shifting (inclination toward excess or deficiency), and the scope of what can be treated. I would also like to hear about the changes of disease—that condition where pathogenic qi gradually infiltrates and spreads, while righteous qi declines, ultimately reaching the point of being incurable. May I?
Qi Bo said: This question is most critical. The Way of medicine, when understood, is as clear as waking in the daylight; when not understood, it is as obscure as closing the eyes in the darkness of night. Those who can accept it and put it into practice—their spirit aligns with the Way; those who devote themselves wholly to experiencing and applying it—their spirit naturally gains attainment. This principle concerning the vitality of life can be written on bamboo slips and silk for transmission, but it cannot be passed down to descendants as lightly as handing over an ordinary object.
The Yellow Emperor asked: What is meant by "waking in the daylight"?
Qi Bo said: Understanding the laws of Yin and Yang is like having a confusion unraveled, like becoming sober after drunkenness.
The Yellow Emperor asked: What is meant by "closing the eyes in the darkness of night"?
Qi Bo said: It is dim and obscure without sound, vast and formless. At this time, the cou li (interstices of the skin and muscles) open and discharge, righteous qi collapses and scatters, pathogenic qi overflows and spreads, transmitting and flowing within the blood vessels, and the great qi (referring to hyperactive pathogenic qi) penetrates deep into the five zang organs, giving rise to abdominal pain and instability of the lower source. In such a condition, one may move toward death, and it is difficult to restore life.
The Yellow Emperor asked: After the great qi penetrates the five zang organs, how does the disease transmit and change?
Qi Bo said:
If the disease first arises in the heart, on the first day it transmits to the lungs, on the third day to the liver, on the fifth day to the spleen, and if it does not resolve after another three days, death ensues. The time of death: in winter, mostly at midnight; in summer, mostly at noon.
If the disease first arises in the lungs, on the third day it transmits to the liver, after another three days to the spleen, on the fifth day to the stomach, and if it does not resolve after another ten days, death ensues. The time of death: in winter, mostly at sunset; in summer, mostly at sunrise.
If the disease first arises in the liver, on the third day it transmits to the spleen, on the fifth day to the stomach, after another three days to the kidneys, and if it does not resolve after another three days, death ensues. The time of death: in winter, mostly at the time when the sun slants in the afternoon; in summer, mostly at breakfast time.
If the disease first arises in the spleen, on the first day it transmits to the stomach, on the second day to the kidneys, on the third day to the urinary bladder, and if it does not resolve after another ten days, death ensues. The time of death: in winter, mostly at the hour of people settling down (the quiet hour of deep night); in summer, mostly at dinner time.
If the disease first arises in the stomach, on the fifth day it transmits to the kidneys, after another three days to the urinary bladder, after another five days upward to the heart, and if it does not resolve after another two days, death ensues. The time of death: in winter, mostly at midnight; in summer, mostly at the time when the sun slants westward in the afternoon.
If the disease first arises in the kidneys, on the third day it transmits to the urinary bladder, after another three days upward to the heart, after another three days to the small intestine, and if it does not resolve after another three days, death ensues. The time of death: in winter, mostly at the time just before dawn; in summer, mostly at dusk.
If the disease first arises in the urinary bladder, on the fifth day it transmits to the kidneys, after another day to the small intestine, after another day to the heart, and if it does not resolve after another two days, death ensues. The time of death: in winter, mostly at the hour of the rooster's crow; in summer, mostly at the hour of shen in the afternoon (3–5 PM).
For all diseases that transmit in this sequential order, there is a definite time of death, and in such circumstances acupuncture should not be used; if during the course of transmission the disease skips one organ, or skips two or three organs, then acupuncture may be used.
1. The Dialectic Between "Holding to One" and "Practicing All": The Yellow Emperor's question concerns the choice of methods—whether to adhere to a single technique or to master them all. Qi Bo's answer embodies the fundamental principle of Traditional Chinese Medicine: "treatment tailored to the individual." The world's therapies are numerous, each suited to different circumstances, and it is neither necessary nor possible for one person to practice them all. The phrase "hold to one without losing, and the brilliance of all things unfolds" highlights the idea of using the Way to govern techniques—holding firmly to the foundation of medicine (the principles of Yin-Yang and deficiency-excess), all methods become tools at one's disposal, without attachment to any particular technique 🌿.
2. "Waking in Daylight" and "Closing Eyes in Darkness"—Two Cognitive States of the Physician: Qi Bo uses the metaphors of "waking in the daylight" and "closing the eyes in darkness" to describe clarity versus obscurity in understanding the laws of Yin and Yang. One who understands Yin-Yang sees the changes of disease as clearly as if in broad daylight; one who does not, faces disease "dim and without sound, vast and formless," and can only watch as the condition deteriorates. This is the most fundamental requirement for a physician's cognitive ability 💨.
3. The Five-Phase Mutual Overcome Sequence of Disease Transmission Through the Five Zang Organs: This is the most essential content of this chapter. Examining the transmission patterns closely:
This indicates that the ancients believed: after exogenous pathogenic qi penetrates deep into the five zang organs, if not intervened upon, it will transmit sequentially according to the mutual overcoming order of the Five Phases, with each step of transmission signifying deeper disease location and increasing severity. Once the full cycle has been traversed, righteous qi is exhausted, and an irreversible "time of death" is reached.
4. The Treatment Principle of "Acupuncture is Permissible When Transmission Skips an Organ": When disease transmits sequentially according to the overcoming order, this is called "sequential transmission," meaning that pathogenic qi is at its peak and righteous qi retreats in defeat at every step—in such cases, acupuncture is unlikely to succeed. If during transmission the disease skips one or more organs (such as heart transmitting directly to spleen, skipping the lungs), this indicates that pathogenic qi is not following the normal sequence and there is still room for recovery—in such cases, acupuncture may be used. This reflects the ancient strategic principle of "avoid the enemy's sharp edge, strike when their vigor is spent" 🩺.
5. Correspondence Between Time of Death and Waxing and Waning of Yin-Yang: The times of death for each zang organ are divided into "winter at XX hour, summer at XX hour," and the pattern is—yin organs die at yin times (winter midnight, the hour of people settling, etc.), yang organs die at yang times (summer noon, sunrise, etc.). This reflects the cosmological view of "like qi responds to like": the Yin-Yang attributes of the body's organs correspond to the Yin-Yang rhythms of nature. Death, as the ultimate moment of the separation of Yin and Yang, tends to occur at a time node consistent with the pathological organ's attribute.
Value dimension: This passage demonstrates the ancients' effort to systematically and regularly understand the process of disease transmission. Over two thousand years ago, proposing a model in which disease transmits between organs along a defined route, and explaining it with Five-Phase generation and overcoming theory, holds significant intellectual value in the history of medical understanding. It reminds clinicians that disease is a dynamic developmental process, and treatment should focus on cutting off the transmission pathways, not merely on the organ currently manifesting pathology—this resonates conceptually with modern medicine's "prevention of complications" and "sequential occurrence of multiple organ dysfunction."
Limitations dimension: It must be clearly stated that the above-mentioned "transmission of one organ per day, death if unresolved after three days" and the times of death belong to the ancients' deductions based on the Five-Phase model rather than conclusions from empirical observation. Modern medicine has no evidence that diseases strictly transmit between organs in the order of "heart→lungs→liver→spleen," nor is there a biological rule that "death occurs at midnight in winter" or "at noon in summer." This content should be understood as the construction of an ancient theoretical model, whose value lies in the systematic thinking it reflects and the alertness it instills regarding the deteriorating trend of disease, rather than a literal predictive function.
Although this chapter discusses the transmission of critical illnesses, from the metaphors of "waking in the daylight" and "closing the eyes in darkness," we can extract practical insights for ordinary people:
The daily significance of "understanding Yin and Yang": It need not be mystified—it can be understood as maintaining a clear awareness of one's own state. Knowing when to move (yang) and when to rest (yin); knowing which foods leave the body feeling comfortable (harmony) and which send signals of discomfort (disharmony). This "wakefulness" toward one's own condition is the foundation of daily health management ⚡.
The focused spirit of "hold to one without losing": Health maintenance methods are numerous—there is no need to be greedy for more. Finding a routine and exercise pattern that suits oneself and can be maintained long-term is far more important than frequently switching between various "health regimens" 🌿.
Disease prevention focuses on "cutting off" transmission: From the model of "sequential transmission," we can see that the ancients' greatest concern was not the onset of disease itself, but its trend of transmission. The lesson for modern people is: take bodily discomfort seriously and address it promptly; do not wait until a problem spreads from a local area to the whole body before responding.
