黄帝内经·素问
The Yellow Emperor asked: In using acupuncture to treat illness, there must surely be guiding principles and rules. What are these "principles" and "rules"?
Qibo replied: Take Heaven as the principle and Earth as the rule, and coordinate with the brilliance of the sun, moon, and stars.
The Yellow Emperor said: I wish to hear this in detail.
Qibo said: In all principles of acupuncture, one must first observe the changes in the sun, moon, stars, the four seasons, and the eight sovereign manifestations of spirit illumination. Only when the movement of qi is settled should one then needle. Therefore, when the weather is warm and sunlight is bright, the human blood flows smoothly and freely, and the defensive qi (the qi that moves along the body surface and provides protection) floats outward, so blood is easily drained and qi moves with ease. When the weather is cold and sunlight is dim, the blood congeals and the defensive qi sinks within. When the moon is new, blood and qi begin to fill, and defensive qi begins to move freely. When the moon is full, blood and qi are replete and muscles are firm. When the moon is waning, the muscles weaken, the channels and collaterals become empty, defensive qi dissipates, and only the physical form remains. Thus one must regulate blood and qi according to the seasons and celestial signs. Therefore, when the weather is cold, do not needle; when the weather is warm, do not hesitate. When the moon is new, do not use draining methods; when the moon is full, do not use tonifying methods; when the moon is waning, do not treat at all. This is called following the celestial seasons and regulating accordingly. Follow the sequence of the seasons and the changes of deficiency and excess, observe the movement of sunlight to determine the position of qi, and stand upright in stillness to await the proper moment. Thus, if one uses draining methods when the moon is new, it will cause deficiency in the viscera. If one uses tonifying methods when the moon is full, it will cause blood and qi to overflow, with blood stagnating in the collaterals — this is called "double excess." If one treats when the moon is waning, it will disrupt the channels, cause yin and yang to intermingle in disorder, make it impossible to distinguish true qi from pathogenic qi, allow evil qi to sink and remain, weaken the exterior while the interior becomes chaotic, and thus licentious evils will arise.
The Yellow Emperor asked: What are the stars and the eight sovereign manifestations used to observe?
Qibo said: The stars are used to calculate the patterns of movement of the sun and moon. The eight sovereign manifestations (the eight seasonal nodal points or the eight directional influences) are used to observe the timely arrival of deficient evils from the eight directions. The four seasons are used to distinguish the locations of spring, summer, autumn, and winter qi, to regulate the body according to the seasons, and to avoid the deficient evils of the eight sovereign manifestations without being invaded by them. If the body is already deficient and then encounters the emptiness of celestial timing, the two deficiencies interact, and the evil qi may reach deep into the bones; once it penetrates, it damages the five viscera. If the physician can diagnose and treat in time, the patient will not be harmed. Thus it is said: the "celestial prohibitions" must not be unknown.
The Yellow Emperor said: Well spoken! Regarding the principle of following the stars, I have heard it. Now I wish to hear about how to follow the ancients and verify in the present.
Qibo said: To follow the ancients, one must first understand the Needle Classic. To verify in the present, one must first understand the cold and warmth of the sun, the fullness and emptiness of the moon, and from this examine the floating and sinking of qi, then regulate the body and observe the immediate response. What is called "observing the unseen" means that the form, qi, nutritive blood, and defensive qi are not revealed externally, yet the physician alone can know them. By combining the cold and warmth of the sun, the fullness and emptiness of the moon, and the floating and sinking of qi in the four seasons, and regulating accordingly, the physician can often perceive things in advance — but these are not manifested externally, hence the phrase "observing the unseen."
Only one who comprehends infinite transformations can transmit the medical Way to later generations. This is what distinguishes the superior physician from the mediocre. Yet because these principles are not outwardly visible, ordinary people cannot see them. Looking, there is no trace; tasting, there is no flavor — so it is called "the unseen," as if divine. Deficient evil is the evil qi brought by the eight sovereign manifestations. Proper evil refers to when the body is fatigued from labor, sweating, and the interstitial spaces are opened, encountering a deficient wind — this evil harms people only lightly, so no one knows its actual condition, no one sees its form or trace. The superior physician treats when the disease is still in its bud, always first examining the qi of the three regions and nine divisions, and treating before it has declined and failed — hence the name "superior physician." The inferior physician only treats once the disease is fully formed, or even after it has already caused damage. What is meant by "treating the already formed" is that one does not understand the disharmony of the qi of the three regions and nine divisions, and it is because of illness that the body declines. Knowing where the disease resides means diagnosing it by locating the diseased pulse among the three regions and nine divisions and then treating it. Hence it is said to "guard the gate" — even without knowing the precise condition visually, one can recognize the manifestation of evil qi.
The Yellow Emperor said: I have heard of tonifying and draining methods, but I have not yet understood their real meaning.
Qibo said: The draining method must rely on the principle of "squaring." What is meant by "squaring" refers to when qi is at its peak, when the moon is just full, when sunlight is just warm, and the body is just stabilized. One inserts the needle on inhalation, then rotates the needle while awaiting the next inhalation, then slowly withdraws the needle on exhalation at the next breath. Thus it is said that draining must use the method of "squaring," allowing the evil qi to leave with the needle. The tonifying method must rely on the principle of "rounding." What is meant by "rounding" is movement and circulation: the needle must be inserted exactly at the point of affliction, and the needle is withdrawn on inhalation. Thus "rounding" and "squaring" do not refer to the shape of the needle, but to the timing and technique of tonification and drainage. Therefore, one who excels at nurturing the spirit must understand the body's fatness and thinness, and the fullness or deficiency of nutritive blood and defensive qí. Blood and qi are the foundation of the human spirit — they must not be tended carelessly.
The Yellow Emperor said: How exquisite! That the human form corresponds with yin-yang and the four seasons, responding in deficiency and excess, with subtle and profound changes — who but you, my teacher, could comprehend all this? Yet you have repeatedly mentioned "form" and "spirit." What is meant by form, and what is meant by spirit? I wish to hear in detail.
Qibo said: First, about form. "Form" refers to the external physical appearance. When the eyes cannot clearly see the condition, one inquires into what ails the patient and searches among the channels. Although the mind understands, one cannot feel it by pressing; one does not know its full details — hence the name "form."
The Yellow Emperor asked: What, then, is spirit?
Qibo said: As for spirit — how subtle it is! The ears cannot hear it, but the eyes perceive it clearly. The heart is opened and the will arrives first; with sudden illumination, one alone understands. In the darkness of the mouth, it is difficult to express in words. Among the multitude who look upon it, only one can perceive it. Though it appears obscure, it shines forth with clarity — like the wind dispelling clouds. Hence it is called "spirit." Only the measurement of the pulse in the three regions and nine divisions can serve as the foundation for observing the spirit, and once the spirit is understood, the specific details of the nine needles need not constrain one's practice.
The core of this chapter is the concept of "Heaven-human correspondence" in choosing the right timing for acupuncture. The ancients believed that human blood and qi moved in cyclical rhythms driven by celestial phenomena — especially the movements of sun and moon and the alternation of cold and warm seasons. Acupuncture, therefore, is not something one does at any moment; one must "await the qi" in accordance with these rhythms: when the weather is warm and the moon is full, blood and qi are more buoyant and replete — suitable for draining excess; when the weather is cold and the moon is waning, blood and qi are more sunken and depleted — inappropriate for random needling. This is integrating medical intervention into natural cycles.
Another central theme is "The superior physician treats the not-yet-formed disease" and "observing the unseen." The skilled physician can detect pathological tendencies before the disease is fully apparent — or before the qi and blood have declined — through fine-grained observation maintained with pulse diagnostics such as the three regions and nine divisions. The inferior physician only applies treatment once the illness is clearly visible, when it is already late, potentially beyond salvage. This emphasis parallels modern preventive medicine and early diagnostics.
The "rounding" and "squaring" discussed for tonification and drainage do not refer to the shape of the needles but to timing and the dynamics of qi: draining lets the evil out at the moment-of-peak-qi when one employs the vector of ebb; tonifying guides the qi to return and settle in a circular, flowing motion (interpreted as uptake movement). Finally, the declaration that "blood and qi are the foundation of spirit and must be nurtured carefully" signals that despite discussing needling techniques, the true focus is conserving the essence-of-blood-and-qi as the foundation of life.
From a modern scientific viewpoint, we acknowledge cyclical phenomena such as circadian rhythms, seasonal variations in sleep, hormone secretion, and immune function. However, the specific assertions like "when the moon is full, blood is full; when the moon is waning, the channels and collaterals are empty" currently lack reproducible physiological evidence and are likely products of ancient natural-philosophical extrapolation, more symbolically suggestive than empirically explanatory.
The underlying concept of "superior physician preventing before rising" echoes to modern proactive health-care practice — attending to early signals of imbalance, respecting lifestyle rhythms, and screening early for illness holds powerful practical relevance. This does warrant caution: descriptions intending mastery in those terms for "unobservable causation hidden as subtle perception — such as spirit" can drift into mysticism easily. So we overlay human-modern implications with 'anticipatory global maintenance,' not mystical experience but informed mindful practice.
Broad speculation on the practices is relevant primarily as philosophical backdrop for medical history. Acupuncture technique direction holds some relevance for master–student succession in academia that cares to differentiate ancient text, historical development lineage etc., yet remains entirely not operational clinical policy or actionable input without matching-up methodologies accepted standard.
