The origins of all diseases are countless. Zhang Yun: The onset of various diseases stems either from external pathogens or internal injuries, and can be categorized into upper, middle, and lower regions. Unregulated emotions (anger, joy, worry, pensiveness, fear) constitute disorders of the Five Zang emotions, causing internal injury to the Zang organs; thus, they originate from the Yin (interior). Clear dampness invading deficiency constitutes Yin pathogens on the exterior; thus, they originate from below. Wind and rain invading deficiency constitute Yang pathogens on the exterior; thus, they originate from above. The initial sites of disease are limited to these three areas. However, as the pathogen infiltrates and spreads, the variations become incalculable.
"Former Master": A respectful term for a senior teacher.
Wind, rain, cold, and heat... divided into three sections: Jia Yi text notes: "Xiang de" (mutual meeting) is read as "Xiang bo" (mutual combat); "Rou jian" (firm flesh) is read as "Rou jian" (between muscles); "Yuan" is read as "Zhen" (true). Ma Yun: The previous section discusses wind, rain, cold, heat, clear air, and dampness, while this section mentions wind, rain, cold, heat, and violent storms. Although the terminology differs, they all belong to external infections. However, these external pathogens cannot harm the human body unless they coincide with the "deficient evil" (Xu Xie, pathological factors arising from abnormal seasonal climates) of heaven. (See *Jiu Gong Ba Feng* chapter in this classic). Nor can they harm the body without the inherent deficiency of human Qi. It is the convergence of heavenly deficiency and bodily deficiency that allows various pathogens to lodge within the physical form. If there is a "real wind" (Shi Feng, winds coming from the direction of residence, which promote growth and nourishment, as described in *Jiu Gong Ba Feng*), and the person possesses robust Qi, then two realities meet. With firm flesh and robust constitution, pathogens cannot lodge in the body. "San Yuan" (Three Rounds/Sections) refers to the "Three Parts." Generally speaking, longitudinally, the human body is divided into upper, middle, and lower parts; transversely, it is divided into exterior, interior, and half-exterior/half-interior. Hence, they are called the three sections of upper/lower and middle/exterior. Zhang Yun: As mentioned later, when deficient evil invades, the cause is exterior; when accumulation forms, the cause is interior; when desires injure the Zang organs, the disease is in Yin. This refers to the three sections of interior/exterior. Zhi Yun: This passage discusses wind/rain injuring the upper part; the next section discusses clear/damp injuring the lower part; the final section discusses emotions injuring the middle part, thereby dividing them into three sections. Brief note: Based on the character "Wai" (external), Zhang's annotation is correct. "Yuan" means number/count, so Ma's interpretation as "part/section" is appropriate.
Therefore... leading to skin pain: Jia Yi text notes: "Di" is read as "Shao" (slightly). Zhang Yun: The following describes the sequence of transmission and lodging of Yang pathogens. Pathogens entering the body must move from the exterior to the interior, starting at the skin. When the exterior is deficient, the skin becomes lax, allowing pathogens to exploit this weakness. When pathogens are at the exterior, hair stands erect, causing shivering and aversion to cold. Cold pathogens damaging Wei Qi leads to stagnation of Blood and Qi, resulting in skin pain. Wherever cold pathogens invade, soreness and pain are common. By observing which meridian is involved, one can determine if it is Yin or Yang, and whether the depth is shallow or deep. In diagnosing exterior syndromes, one should start here. The meaning of the onset of diseases below aligns largely with the *Pi Bu Lun* (Treatise on Skin Regions).
Lodging and not dispersing... the Large Meridians take over: Jia Yi text notes: "Qi tong zhi shi xi" is read as "Qi bing shi tong shi xi" (pain comes and goes intermittently). Zhang Yun: When pathogens are in the hair and skin, treatment should focus on the exterior. If they remain undispersed, they penetrate deeper and lodge in the Luo Collaterals. Since Luo Collaterals are shallower than the Jing Meridians, pain occurs between the muscles. If muscle pain gradually subsides, it indicates the pathogen is leaving the Luo Collaterals to deepen further, and the Large Meridians (Da Jing) subsequently bear the burden. Brief note: Ma interprets "Dai" as intermittent pulse arrest, which is incorrect. Zhi Yun: Da Jing refers to Jing Sui (Meridian Passages). Jing Sui refers to the large collaterals of the Five Zang and Six Fu organs. Essentially, Da Jing is the term used for the main meridians in contrast to Luo Collaterals. Zhi's annotation may be erroneous.
Lodging and not dispersing... prone to fright: Zhang Yun: Luo Collaterals are superficial and floating; Jing Meridials are hidden and deep. When pathogens move from Luo Collaterals to Jing Meridians, they are still considered at the exterior, hence the shivering and aversion to cold. However, since Jing Qi connects to the Zang organs, the patient also becomes prone to fright.
Lodging and not dispersing... stiffness: Jia Yi text notes: "Si zhi ze zhi jie tong" is read as "Si jie ji tong" (four joints immediately painful). Zhang Yun: All Shu points are locations where Jing Qi gathers. Pathogens lodging here reside between the joints and valleys. Thus, when pathogens transmit from Jing Meridians to Shu points, the Six Meridians become obstructed, causing pain and stiffness in the limbs, joints, waist, and spine.
Lodging and not dispersing... body pain: Zhang Yun: The Fu Chong Mai (Hidden Chong Vessel) is the Heng Mai running along the spine. Due to its depth, it is called "Fu" (Hidden). The *Sui Lu* chapter states: "Entering the spine and injecting into the Fu Chong Mai." When pathogens lodge in the Shu points and do not disperse, penetrating deeply here, symptoms such as heavy body and body pain arise. Brief note: The Fu Chong Mai is the Fu Lv Mai (Hidden Spine Vessel) mentioned in the *Nu Lun*. Ma incorrectly identifies Fu Lv Mai as the Lv Jin (Spine Tendons) mentioned later.
Lodging and not dispersing... loose stool like paste: Zhang Yun: When pathogens enter the Zang organs from the Meridians, they lodge in the Stomach and Intestines, causing urgency, abdominal distension, and diarrhea. If Cold, the excrement is clear and cold, with undigested food and water mixing, leading to borborygmus and incomplete digestion (Sun Xie). If Heat does not dominate, turbid urine flows downward, resulting in loose stools and pasty discharge. "Mi" (paste/millet-like) refers to the muddy consistency. Brief note: "Mi" and "Mi" (millet/paste) are interchangeable in ancient texts, referring to decay/paste. "Tang chu mi" likely refers to dysentery with red and white turbid discharge. Zhang's interpretation of "Mi" as deer feces is likely incorrect. Ma defines "Mi" as undigested grain, consistent with Zhi's view, but this fails to distinguish it from the previously mentioned Sun Xie, making the error more severe.
Lodging and not dispersing... stagnation forming accumulation: Ma Yun: The Mo Yuan (Moyuan) is located between the skin and the membranes. Zhang Yun: Outside the intestines and stomach, in the Moyuan, refers to the space between the skin and the inner membranes. These are concealed and tortuous areas where Qi and Blood do not flow easily. If pathogens linger in the center, they stagnate and form accumulations, similar to Malaria. Zhi Yun: Moyuan refers to the fatty membranes outside the intestines and stomach. Lou's *Gang Mu* adopts this view. Thus, when deficient evil invades, reaching the area outside the intestines and stomach, in the Moyuan, constitutes a specific stage. The commentary notes: The aforementioned scenarios all involve pathogens attacking deficiency, lingering without resolving, and transmitting sequentially without fixed lodging. If they lodge firmly with a fixed location, transmission ceases. The concept of "lodging" is explained in the subsequent text.
Or attaching to Sun Collaterals... incalculable: Jia Yi text notes: "Sun Mai" is read as "Sun Luo". Zhi Yun: Fu Chong refers to the Chong Mai running hidden in the abdomen. Moyuan refers to the fatty membranes of the intestines and stomach. Lv Jin refers to the tendons attached to the spine. Huan Jin refers to the tendons circulating within the abdomen. These structures are located anterior, posterior, lateral, and medial to the intestines and stomach. Pathogens follow and lodge to form accumulations. The proliferation of pathogens is incalculable. Brief note: Zhang Yun suggests Moyuan is analogous to Zhong Fu (Front-Mu point of Lung) and Tai Yuan (Source point of Lung). He defines Huan Jin as soft branch tendons. This view is untenable. Zhi's annotation is correct. Huan Jin is essentially Zong Jin (Master Tendon). Wang Shi's commentary on *Wei Lun* states: Vertical tendons flanking the horizontal bone are the true Zong Jin. This corroborates the later text stating that accumulation in Huan Jin resembles Yangming accumulation, aligning with *Wei Lun*: "Chong Mai is the Sea of Meridians, governing seepage and irrigation of valleys, combining with Yangming at the Zong Jin."
Arms and hands... causing frequent sharp pain: Jia Yi text notes: "Bi Shou" is read as "Bo Hu" (note: Bo sounds like 'pai', meaning to break apart); "Ju" is read as "Ju" (to constrain/twist). Between the intestines and stomach, "zhi jian" is read as "wai" (outside), omitting "shui" (water). Above is "fu" (abdomen), omitting "Zhang". Zhang Yun: All fine collaterals are Sun Collaterals. "Ju" means constraint. When pathogens attach to Sun Collaterals to form an accumulation, the mass can migrate up and down. Accumulations in the collaterals of the Large and Small Intestines belong to the Hand Meridians. These collaterals are superficial and lax, unable to constrain the accumulation, causing it to shift between the intestines and stomach. If fluid is present, it gathers and permeates, producing gurgling sounds ("Zhuo Zhuo"). If Cold is present, it causes distension and borborygmus ("Lei Ming"), and mutual traction results in sharp pain. Brief note: Reading "Bi Shou" as "Bo" makes the meaning clearer.
Attaching to the Yangming Meridian... becoming smaller: Zhang Yun: The Foot Yangming Meridian descends alongside the navel. Therefore, its accumulation resides beside the navel. Yangming belongs to the Stomach, which receives Qi from food and drink. Thus, after eating, the accumulation enlarges; when hungry, it shrinks.
Attaching to the Huan Jin... comfort when hungry: Zhang Yun: Huan Jin lies within the muscles, resembling Yangming accumulation. After eating, muscle congestion causes pain; when hungry, Qi recedes, bringing relief. Zhi Yun: Huan Jin are tendons circulating within the abdomen, resembling Yangming accumulation. Distension after eating causes pain; stillness when hunger brings comfort.
Attaching to the Moyuan of the intestines and stomach... pain when hungry: Zhang Yun: Pain in the intestinal Moyuan radiates to the Huan Jin. Fullness after eating expands internally and externally, bringing comfort; emptiness when hungry causes pain. Zhi Yun: Moyuan are the fatty membranes of the intestines and stomach. After eating, fluids seep and moisten externally, bringing comfort; dryness when hungry causes pain.
Attaching to the Fu Chong Mai... feeling like hot water pouring: Zhang Yun: The nature of Fu Chong is as described earlier. Its ascending branch runs along the interior of the back, connecting to the Du Mai. Its descending branch injects into the large collateral of Shaoyin, emerges at Qichuang (Gas Street), follows the medial aspect of the thigh, and enters the popliteal fossa. Pressing the abdomen (old text: thigh, corrected to abdomen) elicits movement under the hand. Lifting the hand causes warm Qi to rise between the thighs. This confirms pathogen attachment to the Fu Chong Mai. Ma Yun: Palpating the accumulation yields pulsation under the hand; lifting the hand causes warm Qi to descend between the thighs. Brief note: *Ju Tong Lun* states: "When Cold Qi lodges in the Chong Mai, the vessels become obstructed, Qi follows, causing panting and pulsation palpable under the hand." This explains the phenomenon.
Attaching to the Lv Jin... unpalpable: Zhang Yun: "Lv" and "Lu" are identical, referring to the vertebral column. The tendons inside the spine are called Lv Jin. Located behind the intestines and stomach, when hungry, the intestines are empty, making the accumulation visible; when full, the intestines are distended and obscure it, making the accumulation invisible. It cannot be felt upon palpation.
Attaching to the Shu Meridians... dry and obstructed orifices: Zhang Yun: Shu Meridians transport Blood and Qi. Obstruction leads to dryness and stagnation of Body Fluids as described. Zhi Yun: Shu Meridians transport Body Fluids and are the large collaterals of the Zang-Fu. Essence from food and drink in the Stomach passes through the Stomach's large collateral to the Zang-Fu's large collaterals, and finally emerges in the skin. When accumulation attaches to the Shu Meridians, the vessel pathway becomes blocked, Body Fluids fail to descend, and the pores of the skin and hair become dry and clogged. This illustrates how pathogens enter from the exterior and descend from above to form accumulations.
These pathogens enter from the exterior and descend from above: Zhang Yun: This summarizes the preceding discussion: pathogens originating from Yang inevitably move from exterior to interior and from top to bottom. Lou Yun: This refers to wind and rain invading the deficiency of Yin, causing disease to start from above and generate accumulation.
Jue Qi then forms accumulation: Jia Yi text adds "Zhi" after "Jue". Zhang Yun: The following explains the formation of accumulation.
Jue Qi arises in the feet... gradually forming accumulation: Jia Yi text reads two " " characters as "Yi". Zhang Yun: This describes accumulation formed by rebellious Cold Qi. Jue Qi is rebellious Qi. Cold rebels in the lower body, causing foot Bi (obstruction), characterized by joint pain, stiffness, and inconvenience. Cold calves lead to stagnant Qi and Blood. Cold Qi moves upward from below into the intestines and stomach. Cold in the intestines and stomach prevents Yang Qi transformation, causing distension. Juice and phlegm outside the intestines are forced together and do not disperse, gradually forming accumulation.
Sudden excessive eating and drinking... accumulation forms: Zhang Yun: This describes accumulation caused by irregular diet and lifestyle. Sudden excessive intake implies rapid,暴饮暴食 (bingyinbao shi - binge eating/drinking). The intestines and stomach cannot digest it promptly, causing juices to overflow into the membranes and mix with Blood, forming Food Accumulation (e.g., pediatric痞疾 pi ji). Alternatively, excessive physical exertion damages the collaterals of Yin and Yang, causing Blood stasis. Blood combines with Cold and juices outside the intestines, forming Blood Accumulation. This is common in those who indulge their appetites and act recklessly. Ma Yun: Injury to Yang meridian collaterals causes external bleeding (nu); injury to Yin meridian collaterals causes internal bleeding and residual blood stasis. Zhi Yun: Yang collaterals ascend; Yin collaterals descend.
Sudden external Cold invasion... accumulation forms: Jia Yi text: "You Nu" is read as "You Kong"; "Liu Shu" as "Xue Shu"; "Yun Li" as "Yun Guo"; "Se Shen" as "Ning Se". Zhang Yun: This describes accumulation caused by emotional internal injury combined with Cold. External Cold attacks, while sorrow and anger injure the interior. Qi rebels due to Cold, blocking the Shu points of the Six Meridians. Warm Qi fails to circulate, causing Yin Blood to coagulate. Blood forms accumulation due to Qi rebellion. This is common in individuals with volatile temperaments. Lou Yun: This refers to clear dampness invading the deficiency of Yin, causing disease to start from below and form accumulation. Brief note: The characters "Liu", "Zi", and "Li" in Jia Yi are errors.
Sorrow and thought injure the Heart... Kidney injured: Jia Yi text adds "Shui" after "Yu Xia". Zhang Yun: Injury to the Heart affects Yang; injury to the Lung affects Qi; injury to the Liver affects Blood; injury to the Spleen affects Ying and Wei; injury to the Kidney affects True Yin. Any injury to the Zang organs results in disease originating from Yin. This section aligns with *Xie Qi Zang Fu Bing Xing Lun*. Lou Yun: This describes emotions injuring the Zang, with disease originating from Yin. Wind/rain invading Yin deficiency starts disease from above; clear/damp invading Yin deficiency starts disease from below. Only when all three sections (exterior/interior) are affected does accumulation fully form.
Do not violate the timing of Heaven: Ma Yun: For example, Spring Qi resides in the Liver, and the phases of the moon (waxing/waning) are relevant. These are examples.
