Huangdi said: Since ancient times, the connection between humans and Heaven is the root of life, and this root lies in Yin and Yang. Within the space between Heaven and Earth, and within the Six Directions, the Earth corresponds to the Nine Provinces, and humans correspond to the Nine Orifices, Five Zang Organs, and Twelve Joints (bone joints), all of which are connected with the Qi of Heaven. (All living beings receive their Qi from Heaven, thus connecting with Heaven is the root of their existence. Heaven generates all things through Yin, Yang, and the Five Phases, so the root of life lies in Yin and Yang. Therefore, within the space between Heaven and Earth and the Six Directions, the Earth's Qi corresponds to the Nine Provinces, while human Qi corresponds to the Nine Orifices, Five Zang Organs, and Twelve Joints, all connecting with the Qi of Heaven. The "Twelve Joints" refer to bone joints. Each hand and foot has three major joints, plus the connections of minor joints, totaling 365 meeting points. *Ling Shu: Xie Ke* states: The Earth has Nine Provinces, humans have Nine Orifices; Heaven has Five Tones, humans have Five Zang Organs; a year has twelve months, humans have twelve joints; a year has 365 days, humans have 360 joints; the Earth has twelve great rivers, humans have twelve primary meridians. Generally, joints are where Shen Qi (Spiritual Qi) travels, corresponding to Heaven's years and months; meridians are where blood flows, corresponding to the Earth's rivers; the nine orifices are the gates for Zang Qi to enter and exit, and the five Zang organs are the storage places for Yin and Yang Qi, thus all connecting with the Qi of Heaven. This chapter discusses how Yin and Yang Qi connect with the Qi of Heaven. Since Heaven belongs to Yang, Yang is discussed first, followed by Yin. Zhu Jigong stated: Tian Yi generates Water, and Qi is the fullness within Kan (Water trigram). "Since ancient times" refers to the True Qi generated since ancient times. "Rooted in Yin and Yang" means that True Qi possesses both Yin and Yang aspects.) Life is generated by the Five Phases, and human Qi is divided into Three Yin and Three Yang. If these patterns are frequently violated, pathogenic Qi will harm the person, which is the foundation of lifespan. (The Ten Heavenly Stems generate the Five Earthly Phases, hence it is said "its generation is five." The Five Earthly Phases correspond upwards to the Qi of Three Yin and Three Yang, hence it is said "its Qi is three." The Three Yin refer to Cold, Dryness, and Dampness; the Three Yang refer to Wind, Fire, and Summer-heat. If one fails to regulate oneself and frequently violates these Three Yin and Three Yang Qi, pathogenic Qi will harm the body and cause disease. Humans are born receiving the Qi of the Five Phases and die by violating them, just as water can carry a boat but also capsize it. Thus, it is said that this is the foundation of lifespan.) When the Qi of the Blue Heaven is pure and clear, human will and intention remain orderly; complying with it makes Yang Qi secure, so even if harmful pathogens exist, they cannot cause harm. This is because one follows the sequence of the seasons. Therefore, the sages preserve their spirit, ingest the Qi of Heaven, and communicate with divine illumination. (Sheng Qi connects with Heaven; thus, when the Qi of the Blue Heaven is pure and clear, human will and intention are orderly. If humans comply with this pure and clear Qi, their bodily Yang Qi becomes secure on the exterior, and even if harmful pathogens exist, they cannot cause harm. This results from following the seasonal sequence and regulating oneself. Thus, sages circulate their spirit and ingest the clear Qi of the Blue Heaven to communicate with their own divine illumination.) Failure to comply leads to internal blockage of the nine orifices, external stagnation of muscles, and dispersion of Wei Qi (Defensive Qi). This is called self-injury, leading to the depletion of Qi. (Violating the pure and clear Qi of Heaven causes the nine orifices to close internally and muscles to stagnate externally, causing the defensive Yang Qi to disperse. This is failing to comply with Heaven's Qi and injuring oneself, resulting in Qi depletion. Human Qi connects with Heaven; violating Heaven's Qi causes human Qi to become inverted.) Human Yang Qi is like the sky and the sun; if it loses its proper position and function, lifespan is shortened and brilliance is obscured. Therefore, the movement of Heaven relies on the brightness of the Sun. Thus, Yang Qi resides above and protects the exterior. (The previous section discussed complying with Heaven's Qi to nourish bodily Yang; here it reiterates that human Yang Qi should be like Heaven and the Sun. If it loses its proper position and operational mechanism, lifespan is shortened and not manifested. Heaven's Qi is pure, clear, and bright, yet its virtue is hidden and its operation is ceaseless, so Heaven's movement relies on the Sun's brightness. Heaven's hidden virtue does not descend, so human Yang Qi resides above. Heaven's communication is manifest beyond the Six Directions and Nine Provinces, so human Yang Qi serves to protect the exterior.)
When affected by Cold, Yang Qi should operate flexibly like a turning door pivot; if daily activities involve panic or disturbance, Shen Qi (Spiritual Qi) will float outward. (Yang Qi is generated from Extreme Yin and moves outward through the Pivot mechanism. Wind-Cold pathogens initially damage the skin-hair layer and Qi level. Therefore, when affected by Cold, bodily Yang Qi should respond outwardly like a turning pivot. Yang Qi governs the exterior, and pathogens lodge at the gate; thus, if daily activities are disturbed, Shen Qi floats out to respond. Shen Qi refers to the Yang Qi of the Spirit-storage organs. Mo Zhongchao noted: The "turning pivot" in this section corresponds to the subsequent "opening and closing." Taiyang governs the exterior and opening, rooted in the Cold Water of the Lower Jiao, so it seeks to emerge via the Pivot. Also, according to *Shang Han Lun*, initial damage to the skin-hair Qi level transforms into heat upon receiving Yang Qi; even if heat is severe, death does not ensue, representing the ability to turn the pivot and respond outwardly. For example, in Taiyang disease with fever, headache, and a deep pulse, the interior must be rescued, indicating Shen Qi cannot float outward, requiring urgent use of Gan Jiang (Dried Ginger) and Fu Zi (Prepared Aconite) to rescue interior Yang Qi and facilitate its outward movement. In Heaven, Yin-Cold pathogens are countered by bodily Yang Qi; thus, when affected by Cold, Yang Qi should emerge as described, fulfilling the principle of "Yang residing above and protecting the exterior.")
When affected by Summer-heat, sweating occurs; if vexed, there is panting and shouting; if quiet, there is excessive talking. The body feels hot like burning charcoal, and symptoms dissipate after sweating. (Heaven's Yang pathogens damage bodily Yang Qi, causing Qi deficiency and external flaccidity, leading to sweating. Excessive heat in the Qi level forces the Heart (which governs vessels), causing mental vexation. The Lung is the canopy of the Heart, so vexation leads to panting and shouting. If there is no vexation but quietness, the pathogen remains in the Qi level, damaging Qi and causing Shen Qi deficiency, leading to excessive talking. *Mai Yao Jing Wei Lun* states: Speaking faintly and only speaking occasionally throughout the day indicates Qi depletion. Heaven's Yang pathogens damage Yang Qi; the interaction of two Yangs causes the body to feel hot like burning charcoal. Yang-Heat pathogens are resolved by bodily Yin fluids, so symptoms dissipate after sweating. According to *Shang Han Lun*: Frequent spontaneous sweating indicates Disharmony of Wei Qi; inducing sweat again resolves it when Ying and Wei harmonize. Thus, sweating due to Summer-heat indicates Summer-heat damages Yang and causes Wei Qi disharmony. Dissipation after sweating indicates resolution upon Ying-Wei harmony.)
When affected by Dampness, the head feels heavy as if wrapped. If Damp-Heat is not cleared, large tendons shorten and small tendons elongate. Shortening causes spasms/contracture, while elongation causes flaccidity/paralysis. (This section describes Dampness damaging Yang Qi and presenting such symptoms. Yang Qi, like Heaven and the Sun, tends upward. Dampness injures the lower part first. Removing disease involves progression from bottom to top. Yin-Damp pathogens ascend to harass Yang Qi and obscure clarity, causing the head to feel wrapped. Dampness damages Yang Qi, transforming into Heat due to Yang. Yang Qi, when soft, nourishes tendons. Damage to Yang Qi prevents it from nourishing tendons, causing large tendons to shorten and small tendons to elongate. Large tendons connect within bone joints, so郁热 (stagnant heat) causes shortening; small tendons lie outside bone and flesh, so Dampness causes elongation. Shortening leads to contraction and spasms; elongation leads to laxity and flaccidity. This illustrates how Cold, Summer-heat, and Dampness damage Yang Qi.)
When affected by Qi pathogens, swelling occurs. If the Four Limbs alternate in affliction, Yang Qi is exhausted. (This summarizes the preceding text: external pathogenic factors damaging Qi cause swelling. *Yin Yang Bie Lun* states: Accumulation in Yang causes swelling of the four limbs. Damage to Yang Qi prevents circulation, causing Ying Blood to stagnate and swell. "Four Dimensions" refers to the four limbs. The limbs are the root of all Yang Qi. When Qi is damaged by pathogens, the Yang Qi of the limbs alternates in failure, leading to exhaustion of Yang Qi. Zhu Jigong stated: "Four Dimensions" refers to the four seasons. *Zhi Zhen Yao Da Lun* states: Carefully observe the four dimensions; prognosis returns, endings are visible, beginnings are known. The Qi of Hand and Foot Yang meridians peaks in the four seasons, waxing and waning like seasonal changes, hence "Four Dimensions alternate." Another question: Why mention only three Qi (Cold, Summer-heat, Dampness) among the Six Pathogens? Answer: Six Qi arise from the Five Phases; Summer-heat and Heat belong to Fire. Yang Qi and Wei Qi are distinct. Wind damages Wei and simultaneously Yang, hence separately mentioned as "Wind lodging in excess Qi." The Classic states: Dryness overcomes and causes dryness. Dryness pathogens damage Blood but not Qi.)
Yang Qi, when subjected to excessive mental or physical labor, expands excessively, leading to Essence exhaustion. Accumulating into Summer, this causes Jian Jue (Frying Collapse). Eyes become blind unable to see, ears closed unable to hear, chaotic like a collapsing dam, and unceasing like a bursting dike. (This section discusses labor damaging Yang Qi. *Jin Gui Yao Lue* states: Labor diseases present with large pulses, irritability in hands and feet, worsening in Spring/Summer, improving in Autumn/Winter, spontaneous emission of cold essence, soreness preventing walking. The key to Yin and Yang is that Yang density ensures stability. Excessive labor causes Yang Qi to expand outward; without Yang's warmth and stability, Yin Essence leaks and depletes internally. In Autumn/Winter, Yang Qi stores inward; in Summer, Yang Qi floats outward, becoming increasingly deficient and leading to Jian Jue. Deficient Essence causes blindness and deafness. The Bladder is the Officer of the Metropolis, storing fluids, and belongs to the Taiyang Fu organ. Taiyang governs all Yang Qi; damage to Yang Qi damages the Fu organ. "Kui" means leaking, describing the failure of the Metropolis to store Essence; "Nuan" describes flowing, indicating unceasing emission of cold essence.)
Yang Qi, during extreme anger, causes Form and Qi to sever, with Blood pooling above, leading to Bo Jue (Thrusting Collapse). Injury to tendons causes flaccidity, making limbs seem unusable. (Anger damages Yang Qi. Yang Qi converges in the skin and interstices. Extreme anger causes Qi to rebel upward, severing the rotational mechanism of Qi in the form. "Wan" means lush/proliferating; Blood follows Qi and proliferates upward. "Bo" means pressing/thrusting; simultaneous rebellion of Qi and Blood causes Thrusting Collapse. Yang Qi softens and nourishes tendons. Vessels moisten bones/tendons and benefit joints. Damage to Yang Qi and upward reversal of Blood injures tendons. Flaccid tendons make limbs seem uncontrollable. The previous section discussed external causes damaging Yang Qi; this section discusses how labor and extreme anger also damage Yang Qi.)
Sweating limited to one side (Pian Ju) leads to hemiplegia (Pian Ku). Sweating exposed to dampness generates acne-like boils (Cuo Fei). Changes from rich food and alcohol lead to carbuncles (Ding). Receiving pathogens is like holding an empty vessel. Labor sweat exposed to wind, cold thinning causes zha (pimples), stagnation causes cuo (acne). (Ju means dampness; Cuo means small boil; Zha resembles rash; Fei refers to red lesions on face/nose. This section states Yang Qi guards the skin externally and fills the limbs, similar to Heaven's Qi operating beyond the Six Directions and Nine Provinces, solidifying Yin. If sweating is limited to half the body (dampness/stagnation), it indicates Yang Qi deficiency failing to permeate the body, predisposing to hemiplegia. Sweating exposed to dampness causes Damp-Heat to stagnate in the skin, generating Cuo and Fei. "Gao Liang" refers to rich flavors. Rich flavors damage Form, and Qi is damaged by flavor; when Form and Qi are damaged, muscle interstices become deficient. Heat-toxins from rich foods reverse in the flesh理 (texture) and often generate large carbuncles. Because skin-interstices are deficient, heat-toxins exploit them, like holding an empty vessel. Labor sweat exposed to wind allows Cold-Damp to thin the skin, causing Zha and Cuo. Zha and Cuo/Fei are mild conditions of Blood stagnation in the superficial skin, indicating Yang Qi guarding the skin is attacked by pathogens, causing pale seepage of blood in hair follicles. Thus: "Sweating limited to one side leads to hemiplegia" indicates Yang Qi, like Heaven and Sun, should pervade the Nine Provinces. "Generating Cuo/Fei, cold thinning causes Zha" indicates Yang Qi's external guard lies in the hair follicles. "Changes from rich food lead to carbuncles" indicates Yang Qi's convergence in the interstices. Zhu Jigong stated: The Classic says, slight imbalance disperses Qi, dispersal leaves skin empty. Also: Interstices are where the San Jiao converges Yuan Zhen (Original Truth). Form consumes flavor; if Form-Qi is deficient, rich flavor toxins exploit it, hence "receiving like an empty vessel.")
Yang Qi, when refined, nourishes the Spirit; when soft, nourishes the tendons. (Continuing from above, Yang Qi internally nourishes the Spirit of the Five Zang Organs and externally nourishes sinews/bones, not merely converging in muscle interstices and guarding the skin-hair. It has opening/closing and exiting/entering functions. The Classic states: Flavors enter the mouth, store in stomach/intestines, nourish Five Qi; when Qi harmonizes, fluids form, and Spirit arises. Yang Qi is the essence of grain/water, thus first nourishing the Spirit of the Five Zang Organs. "Soft" refers to the nascent Qi of Shaoyang. Initial subtle Yang nourishes tendons, hence Shaoyang generates tendons. Mo Zijin asked: The beginning discusses Spirit/Qi rooted in True Nature, why is it also nourished by the Five Flavors? Answer: Essence, Qi, and Spirit have both Pre-Heaven and Post-Heaven aspects. Pre-Heaven Spirit/Qi relies on Post-Heaven grain/water for generation and nourishment. Hence: "Two Essences interacting creates Spirit." The two Essences are Tian Yi Essence and Grain/Water Essence.)
If opening and closing mechanisms fail, Cold Qi enters, causing severe stooping (Da Lou). Cold sinking into vessels causes goiters (Ying); lingering in muscle interstices, acupoint Qi transformation weakens, transmitting to cause fear and惊骇 (fright). Ying Qi does not follow, reverses in flesh texture, causing abscesses/swellings (Yong Zhong). (Opening governs exterior during the day; Closing gathers inward at dusk. Losing opening/closing mechanism allows Cold Qi to invade internally. Back is Yang; Yang deficiency allows Cold pathogens to bi-block the back, causing stooping, as described in *Jin Gui* as Bi pain along the spine. If Yang deficiency fails to guard Ying Blood, pathogens sink into vessels causing goiters, lingering in muscle interstices, as *Jin Gui* describes as Horse Knife Goiter. If acupoint Qi transformation is deficient, pathogens transmit internally, harassing Spirit-storage organs. Heart governs vessels; Spirit damage causes fear and loss of self. Liver governs Blood; thus disease manifests as fright. *Jin Gui Yao Lue* states: Pathogens entering meridians/organs constitute internal causes. Pathogens entering acupoints/internal organs harass Zang Qi. If pathogens reverse in flesh texture/Qi level causing Yin-Yang disharmony, abscesses form. The Classic states: Excess Yang Qi and stagnant Ying Qi cause abscesses. Yin-Yang blockage and clashing heat transform into pus. This explains Yang insecurity allowing pathogens to attack nourished tendons (causing stooping) and internal Spirit (causing fear/fright), emphasizing Yang's external protection. Jigong stated: External protection prioritizes skin-hair; if insecure, pathogens enter flesh/meridians. Mo Zijin stated: Rich food changes reverse in flesh texture causing carbuncles; external pathogens reverse in flesh texture causing abscesses. Skin-hair and flesh texture are governed by Yang Qi. Thus: "Purity closes/rejects muscle interstices, pathogens cannot harm." If muscle interstices are dense, even if pathogens attack skin-hair, it remains only mild Cuo/Fei.)
Unfinished魄汗 (Poh Sweat/Sweat associated with Lung), form weakens and Qi scorches, acupoints close, developing Feng Nue (Wind Malaria). (Note: Yu characters pronounced Shu. This section discusses Surface Qi and Pathogenic Qi sinking together into muscle interstices causing Malaria. Lung governs skin-hair; unfinished Poh Sweat indicates Surface Pathogen remains. "Form weak" means deficient muscle interstices. Sparse interstices allow Surface Yang Pathogen to sink together. Cold Pathogen on surface transforms into Heat following Yang, hence Qi scorches. Although pathogens sink into muscle interstices, Surface Qi does not enter meridians, so acupoints close. Feng Nue is malaria with heat but no chills. Surface Yang Pathogen meets Wei Qi, causing fever. Surface Qi is Taiyang Qi. Muscle interstitial Qi is Yuan Zhen Qi of Five Zang Organs. *Jin Gui Yao Lue* states: Interstices are where San Jiao converges Yuan Zhen. Also: Unobstructed Yuan Zhen of Five Zang Organs ensures health. *Ling Shu* states: San Jiao and Bladder correspond to interstices and hair. San Jiao Qi connects interstices; Taiyang Qi governs skin-hair. Thus, Surface Pathogen sinking into muscle interstices damages Yuan Zhen Qi, while Taiyang Qi remains external. If interstitial pathogens linger, they transfer to acupoints, combining Five Zang Meridian Qi. This section discusses robust Surface Qi but deficient Muscle Qi, causing Surface Qi and Pathogen to sink together into muscle interstices. Taiyang Qi does not combine with Five Zang Meridian Qi, so acupoints close. This annotation should be read with *Shang Han Lun* commentary.)
Therefore, Wind is the beginning of all diseases. Purity and stillness close/reject muscle interstices; even with great Wind and severe toxins, harm is avoided, because one follows the seasonal sequence. (This reiterates nurturing Yuan Zhen Qi and the necessity of dense muscle interstices. Cold/Heat initially damage skin-hair; Wind penetrates directly into muscle interstices. Wind moves swiftly and changes frequently; entering muscle interstices affects meridians, causing Heat in Middle, Cold in Middle, hemiplegia, accumulations/masses, Fu organ diseases, or Zang organ death. Pathogenic excesses are countless, hence "Wind is the beginning of all diseases." Complying with Heaven's pure Qi and regulating Primordial Spirit ensures dense muscle interstices, avoiding harm from great Wind/severe toxins. This follows seasonal sequence and nurturing. Muscle interstitial Qi is Yuan Zhen of Five Zang Organs, thus should be regulated according to seasonal/Five Phase Qi. *Yao Lue* states: Unobstructed Yuan Zhen of Five Zang Organs ensures health; without physical decline, pathogens cannot enter interstices. Previous sections discussed Cold/Summer-heat/Dampness damaging Surface Yang, advising against labor damaging Yang; this section discusses Wind directly damaging muscle interstices, advising densification of Yuan Zhen.)
If disease persists, it transmits and transforms; if Upper and Lower do not connect, even good doctors cannot help. Death from Yang accumulation occurs because Yang Qi is blocked; blocked conditions require purging. Without urgent correct treatment, incompetent physicians ruin the case. (Persistent disease means pathogens remain. Transmission: starting in skin-hair, remaining in muscle interstices, then meridians/acupoints, then Mu Yuan/Zang-Fu. Transformation: changing to Cold, Heat, Dryness/Stagnation, or Dampness/Diarrhea. Heaven has Six Excess Pathogens; the body has Six Qi transformations. Long-term transmission/transformation causes Yin-Yang of Upper and Lower to disconnect; even skilled doctors cannot cure. Disease in Yang branch accumulating to death results from long-term transmission. Skilled doctors should urgently assist Yang Qi to block pathogens and prevent transmission. Blocked conditions require purging pathogens to prevent retention. Failure to use correct treatment urgently leads to failure by incompetent physicians.)
Yang Qi governs the exterior daily. At dawn, Human Qi generates; at noon, Yang Qi peaks; at sunset, Yang Qi declines, and Gate Qi (pores) close. Therefore, evening requires gathering and rejecting; do not disturb sinews/bones, do not expose to fog/dew. Reversing these three times leads to physical exhaustion. (Summarizing opening/closing of Yang Qi, emphasizing external protection. *Ling Shu* states: Spring generates, Summer grows, Autumn harvests, Winter stores; this is Qi's norm, and humans comply. Dividing a day into four seasons: Morning is Spring, Noon is Summer, Sunset is Autumn, Midnight is Winter. Morning sees initial Human Qi generation, hence clarity at dawn. Noon sees growth of Human Qi, overcoming pathogens. Evening sees decline. Midnight sees entry into Zang Organs. Thus, evening gathers Qi, rejects pathogens, avoids disturbing sinews/bones/labor, and avoids fog/dew (requiring purity). Reversing this leads to physical exhaustion by pathogens. "Gate Qi" refers to Xuan Fu (mysterious portals). "Three Times" refer to dawn, noon, sunset.)
Qibo said: Yin stores Essence and acts frequently (Qi Ji); Yang protects the exterior and secures it. (Life's root lies in Yin and Yang; Yang is born from Yin. Thus, the Emperor discussed Yang first, and Bo returned to discuss Yin. "Ji" means frequent/numerous. Yin governs storing Essence...)
