《骨空论》说：任脉，起始于中极穴下方，向上经过阴毛边缘，沿着腹部内部上行，经过关元穴，到达咽喉，再向上至下颌，沿着面部进入目内眦。
（这是说明任脉之气的起始和终止之处。任脉是奇经八脉之一。中极穴位于脐下四寸，说它起于中极之下，实际上是始于会阴穴。
两阴之间由会阴穴沿腹部前行，督脉则由会阴穴沿背部前行。从会阴穴以上到曲骨穴处的阴毛边缘，横骨上方、中极穴下一寸的凹陷处，脉搏应手跳动，接着沿着腹部内部经过中极穴，向上经过关元、气海、下脘、中脘、上脘、巨阙、膻中，到达廉泉穴前的承浆穴，再向上经过喉咙，其脉气上行至下颌，沿着头面，进入眼睛。）冲脉，起始于气街穴，与足少阴肾经并行，夹着肚脐两侧上行，到达胸中后散开。
（这是说明冲脉的起始和终止之处。冲脉也是奇经八脉之一。任脉当脐中而上行，冲脉夹在脐旁两侧而上行，起始于气街穴，并合足少阴肾经，夹脐上行至胸中而散开。气街是一个穴位名称，位于阴毛边缘两旁，鼠鼷（腹股沟）上方同身寸一寸处。说冲脉起始于气街，也是指从少腹内部，与任脉并行，直到此处，乃是沿着腹部而行。又说冲脉、任脉，都起始于胞宫（子宫），向上沿着脊柱内部，成为经络之海；其浮行于体表的分支，沿着腹部各行，汇聚于咽喉，分开后联络口唇。由此说来，任脉、冲脉，都是从少腹内部，上行并由中极穴下方、气街穴内部经过，这是很明确的。）任脉发生病变，男子会出现内脏结聚成七种疝气，女子会出现带下病和瘕聚（腹部包块）。
（这是说明任脉致病的情况。“内”指腹部。腹中的正气，是任脉运行的路径，所以如果生病，就会像这样：男子表现为七种疝气，女子表现为瘕聚。所谓七疝，按照《内经》各篇记载，有狐疝、风疝、肺疝、脾风疝、心风疝、心疝、肝风疝、肾风疝，还有妇人疝、男子疝、厥疝、㿗疝、疝气，我曾总计其数量，包括五脏疝，以及狐疝、㿗疝等。其大义都在各篇中可见。后来朱丹溪提出的七疝，分为寒、水、筋、血、气、狐、㿗。《袖珍方》中的七疝，分为厥、㿗、寒、气、盘、附、野狼。似乎丹溪的说法符合经典旨意，虽然名称各异，但岂能超出《内经》的范围呢！然而世人只知道下部有病称为疝，哪里知道五脏都有疝病！又只知道男子有疝，哪里知道女子也有！大概都是不考察《内经》的缘故罢了。瘕聚，就是积聚。《大奇论》说：三阳脉急则为瘕。后世有八瘕的说法，也是因七疝之名，于是就有了八瘕的名称。即蛇瘕、脂瘕、青瘕、黄瘕、燥瘕、血瘕、狐瘕、鳖瘈。这些《内经》中并没有记载。）冲脉发生病变，会出现气逆和腹中拘急疼痛。（这是说明冲脉致病的情况。冲脉起始于气街，并合足少阴肾经夹脐上行，到达胸中散开，那么“里”就是指它所运行的脉络。生病时气逆而不能上行，怎么能到达胸中散开呢！气聚积在腹中不能散开，怎么能避免任脉所行的腹部拘急呢！）督脉发生病变，会出现脊柱强直、身体向后反折。
（督脉也是奇经脉。任脉、冲脉、督脉，同源而分三支，所以《内经》有时称冲脉为督脉。怎么证明这一点呢？现在的《甲乙经》及古代《经脉流图注经》，把循行于背部的称为督脉，自少腹直上的称为任脉，也称其为督脉，这是以背腹阴阳不同来命名。任脉自胞宫经过，带脉过脐而上，所以男子生病表现为内脏结聚成七种疝气，女子生病则表现为带下和瘕聚；冲脉夹脐而上，并合少阴经上行至胸中，所以冲脉生病表现为气逆和腹中拘急。因为督脉向上沿着脊里，所以督脉生病，就会出现脊柱强直、身体向后反折。）督脉，起始于少腹以下骨骼中央，女子进入联系廷孔（尿道口）。
（这也如同任脉、冲脉起始于胞宫一样。其实它是起始于肾下，至于少腹，则下行于腰横骨围成的中央。所谓系廷孔，是指窈漏（阴道口），靠近前阴的穴位，因为它与前阴相连属于中部，所以叫这个名字。）那个孔，是溺孔（尿道口）的末端。
（孔，就是窈漏。窈漏之中，其上有溺孔。端，指阴廷，在此溺孔的上端。而督脉从骨围中央则向下延伸。）它的别络沿着生殖器，汇合于纂间（肛门与前阴之间），环绕纂后，
（督脉的别络，自尿孔的末端分开各行，向下沿着生殖器汇合于纂间。所谓间，指前阴和后阴之间的部位。从两阴之后，又分开而行，环绕纂后。）别行绕过臀部，到达足少阴肾经，与足太阳膀胱经的中络相合，沿足少阴经上行至大腿内侧后缘，贯穿脊柱，归属于肾，
（“别”，指别络，分开各行。足少阴肾经的络脉，自大腿内侧后缘，贯穿脊柱归属于肾；足太阳膀胱经的外行络脉，循行髀枢络股阳而下，其中行者，向下贯穿臀部，至咽中与外行络相合，所以说“至少阴与巨阳中络，合少阴上股内后廉，贯脊属肾”。）与足太阳膀胱经起始于目内眦，上行至额部，交会于头顶，进入络属脑部，复出分别下行项部，沿着肩膊内侧，夹脊柱抵达腰部中间，进入沿着骶骨络属肾脏；
（接绕臀部上行。）男子循阴茎下行至纂间，与女子相同，其直行者，自少腹直上，贯穿脐中央，向上贯穿心脏，进入喉咙，上行至下颌，环绕嘴唇，向上连接两眼之下的中央。
（自与足太阳膀胱经起始于目内眦，下至女子相同之处，并包括督脉的别络。其直行者，自尾骨上循脊里，而至人中。自其少腹至上，至两眼之下的中央，并包括任脉的行径，而说是督脉所系，由此说来，任脉、冲脉、督脉名称不同但实质同一。）这些经脉生病，会从少腹向上冲撞心脏导致心痛，大小便不通，称为冲疝。
（寻找这种生病情况，正是任脉的病。《内经》称之为冲疝，正是为了区分督脉的主病而异其名目。）女子不孕，小便不利、痔疮、遗尿，咽喉干燥。
（也是因为冲脉、任脉都自少腹上至于咽喉，又以督脉循行生殖器，汇合于纂间，环绕纂后，别行绕过臀部，所以出现不孕、小便不利、痔疮、遗尿、咽喉干燥等症状。称之为任脉，是因为女子得之以任养胎。所以《内经》说：此病女子不孕。称之为冲脉，是因为其气上冲。所以《内经》说：此生病从少腹上冲心而痛。称之为督脉，是因为它总督统领经脉之海。由此三阴经或许相通？然而任、冲、督三脉，同源而起三枝，督脉由会阴而行背部，任脉由会阴而行腹部，冲脉由气冲而行足少阴经，只有督脉出会阴而起，而会阴穴在少腹之下，横骨的中央，女子进入联系廷孔，循行生殖器，汇合于纂间，又从两阴之后，又有别络，分开而行，环绕臀部肌肉，向内连贯脊柱，归属于肾。那足太阳膀胱经的络脉，从外行者，循行髀枢络股阳，而下其中行者，向下贯穿臀部，至咽中与外行络相合。足少阴肾经，自大腿内侧后缘，贯穿脊柱，归属于肾，又与足太阳膀胱经起始于目内眦，上行至额部，交会于头顶，向上进入络属脑部，复出分别下行项部，沿着肩膊，夹脊柱，抵达腰部中间，进入沿着骶骨，络属肾脏，一如足太阳膀胱经经脉所行的路线。然而督脉、任脉，名称虽异，而气脉并无不同，督脉所行的路径，一如任脉的行径，所以自少腹之上者，贯穿脐中央向上贯穿心脏进入喉咙，上行至下颌环绕嘴唇，向上连接两眼之下的中央，督脉生病的情况，又如任脉的病，从少腹上冲心而痛，大小便不通称为冲散，女子所生的疾病，一如任脉、冲脉的病，所以这些经脉相交引发病症，也互用名称。）
The *Gu Kong Lun* (Treatise on Bone Labyrinths) states: The Ren Mai (Conception Vessel, 任脉) originates below the Zhongji point (CV3), ascends to the pubic hair margin, follows the interior of the abdomen, passes through the Guanyuan point (CV4), reaches the throat, ascends to the chin, follows the face, and enters the eyes.
(This describes the origin and termination of the Qi of the Ren Mai. The Ren Mai is one of the Eight Extraordinary Vessels. The Zhongji point is located four cun below the umbilicus; saying it originates below Zhongji actually begins at the Huiyin point (CV1).
Between the two yin organs, the vessel travels from Huiyin along the abdomen, while the Du Mai (Governing Vessel, 督脉) travels from Huiyin along the back. From above Huiyin to the pubic hair margin at the Qugu point (CV2), in the depression one cun above the Henggu point (CV2) and below Zhongji, the pulse beats under the fingers. It then follows the interior of the abdomen through Zhongji, ascending through Guanyuan, Qihai (CV6), Xiawan (CV10), Zhongwan (CV12), Shangwan (CV13), Juque (CV14), Tanzhong (CV17), reaching Chengjiang (CV24) before the Lianquan point (CV23), then ascending through the throat. Its pulse qi ascends to the chin, follows the head and face, and enters the eyes.) The Chong Mai (Penetrating Vessel, 冲脉) originates at the Qichong point (ST30), runs parallel with the Foot-Shaoyin Kidney Meridian, ascends flanking both sides of the umbilicus, and disperses in the chest.
(This describes the origin and termination of the Chong Mai. The Chong Mai is also one of the Eight Extraordinary Vessels. The Ren Mai ascends along the center of the umbilicus, while the Chong Mai ascends flanking both sides of the umbilicus, originating at the Qichong point, merging with the Foot-Shaoyin Kidney Meridian, ascending flanking the umbilicus to disperse in the chest. Qichong is an acupoint name, located one cun above the inguinal region (shuxi) on both sides of the pubic hair margin. Saying the Chong Mai originates at Qichong also refers to traveling from within the lower abdomen, running parallel with the Ren Mai until this point, following the abdomen. It is also stated that the Chong Mai and Ren Mai both originate in the Baozhong (Uterus/Womb, 胞中), ascend along the interior of the spine, serving as the Sea of the Collaterals; their branches floating outward follow the abdomen separately, converge at the throat, and diverge to connect with the lips and mouth. From this, it is clear that the Ren Mai and Chong Mai ascend from within the lower abdomen, passing below the Zhongji point and within the Qichong point.) When the Ren Mai is diseased, men develop seven types of internal hernias (Qishen, 七疝), and women develop leukorrhea and Jiaju (abdominal masses, 瘕聚).
(This describes pathology of the Ren Mai. "Internal" refers to the abdomen. The central Qi of the abdomen is the pathway of the Ren Mai; thus, when diseased, it manifests as such: in men as seven types of hernias, in women as Jiaju. Regarding the seven hernias, according to various chapters of the *Neijing*, there are Hu hernia, Feng hernia, Lung hernia, Spleen-Feng hernia, Heart-Feng hernia, Heart hernia, Liver-Feng hernia, Kidney-Feng hernia, as well as female hernia, male hernia, Jue hernia, Tui hernia, and Shenqi hernia. I have counted them, including Five-Organ hernias, as well as Hu hernia and Tui hernia. Their main principles are found in the respective chapters. Later, Zhu Danxi's seven hernias are categorized as Cold, Water, Sinew, Blood, Qi, Fox, and Tui. The *Xiuzhen Fang* categorizes seven hernias as Jue, Tui, Cold, Qi, Pan, Fu, and Yelang. It seems Danxi's classification aligns with the classic intent; although names vary, do they not fall within the scope of the *Neijing*! However, people only know diseases in the lower part as hernias, not realizing all five organs can have hernias! Nor do they know women can have hernias! This is likely due to a failure to examine the *Neijing*. Jiaju refers to accumulation. The *Da Qi Lun* states: Urgency in the Three Yang vessels leads to Jia. Later generations introduced the concept of Eight Jia, derived from the name of Seven Hernias. These include Snake Jia, Fat Jia, Green Jia, Yellow Jia, Dry Jia, Blood Jia, Fox Jia, and Turtle Jia. These are not mentioned in the *Neijing*.) When the Chong Mai is diseased, there is rebellious Qi and tension/pain in the interior.
(This describes pathology of the Chong Mai. The Chong Mai originates at Qichong, merges with the Foot-Shaoyin Kidney Meridian, ascends flanking the umbilicus, and disperses in the chest. Thus, "interior" refers to its meridian pathway. When diseased, Qi rebels and cannot ascend, how can it reach the chest to disperse? Qi gathers in the abdomen and cannot disperse, how can it avoid the tension of the Ren Mai's abdominal pathway?) When the Du Mai is diseased, there is stiffness of the spine and opisthotonos (body bent backward, 反折).
(The Du Mai is also an extraordinary vessel. The Ren, Chong, and Du Mai share one source but branch into three; thus, the *Classic* sometimes refers to the Chong Mai as the Du Mai. How is this proven? Current texts like the *Jia Yi Jing* and ancient *Jingmai Liutu Zhu Jing* refer to the pathway along the back as the Du Mai, and the straight pathway from the lower abdomen as the Ren Mai, also calling it Du Mai. This naming distinguishes based on the yin-yang of back and front. The Ren Mai passes through the Baozhong, and the Dai Mai passes over the umbilicus upward. Thus, men's disease manifests as internal seven hernias, women's disease as leukorrhea and Jiaju; the Chong Mai ascends flanking the umbilicus, merging with the Shaoyin Meridian to the chest, so Chong Mai disease manifests as rebellious Qi and interior tension. Because the Du Mai ascends along the spinal interior, Du Mai disease manifests as spinal stiffness and opisthotonos.) The Du Mai originates from the central bone below the lower abdomen. In women, it enters and connects to the Tingkong (urethral opening/vaginal opening, 廷孔).
(This is similar to the Ren and Chong Mai originating in the Baozhong. Actually, it originates below the kidney, reaches the lower abdomen, and descends to the center surrounded by the transverse bone of the waist. "Connecting to Tingkong" refers to the Yaolou (vaginal opening), near the anterior orifice. Because it is connected to the anterior yin and belongs to the middle, it is named so.) That orifice is the end of the Niao Kong (urinary meatus, 溺孔).
(The orifice is the Yaolou. Within the Yaolou, above it is the Niao Kong. "End" refers to the Yin Ting, at the upper end of this urinary meatus. And the Du Mai extends downward from the center of the bone surround.) Its collateral follows the external genitalia, converges at the Zuanjian (space between anus and genitals, 纂间), and winds around the posterior Zuan,
(The collateral of the Du Mai diverges from the end of the urinary meatus, travels down along the external genitalia, and converges at the Zuanjian. "Jian" refers to the space between the anterior and posterior yin. From behind these two spaces, it diverges again and winds around the posterior Zuan.) diverges to wind around the buttocks, reaches the Foot-Shaoyin, and merges with the Middle Collateral of the Great Yang (Foot-Taiyang Bladder Meridian, 巨阳中络), ascending along the inner posterior aspect of the thigh, piercing the spine, and connecting to the Kidney,
("Diverge" refers to the collateral, traveling separately. The collateral of the Foot-Shaoyin Kidney Meridian ascends from the inner posterior thigh, pierces the spine, and connects to the Kidney; the outer-running collateral of the Foot-Taiyang Bladder Meridian follows the hip pivot and lateral thigh downward, while its middle runner descends through the buttocks to the pharynx, merging with the outer-running collateral. Hence, it says "reaches Shaoyin and merges with the Middle Collateral of Great Yang," ascending along the inner posterior thigh, piercing the spine, and connecting to the Kidney.) and starts with the Taiyang at the inner canthus of the eye, ascends to the forehead, crosses the vertex, enters and connects to the brain, exits, diverges, and descends down the neck, follows the medial shoulder blade, flanks the spine to the middle of the waist, enters and follows the paraspinal muscles to connect to the Kidney;
(Continues winding up from the buttocks.) In men, it follows the penis down to the Zuan, identical to women. Its straight pathway ascends directly from the lower abdomen, pierces the center of the umbilicus, ascends through the Heart, enters the throat, ascends to the chin, circles the lips, and ascends to connect to the center below the two eyes.
(From starting at the inner canthus with the Taiyang, descending to be identical in women, including the collateral of the Du Mai. Its straight pathway ascends from the coccyx along the spinal interior to the Renzhong. From the lower abdomen upward to the center below the eyes, including the pathway of the Ren Mai, yet described as connected to the Du Mai. From this, we see the Ren, Chong, and Du Mai have different names but the same substance.) Diseases arising here involve Qi rushing from the lower abdomen to the heart causing pain, and inability to pass urine or stool, called Chongshan (Chong Hernia, 冲疝).
(Investigating this pathology, it is precisely a disease of the Ren Mai. The *Classic* calls it Chongshan to distinguish the Du Mai's primary pathology by a different name.) In women, infertility, strangury, hemorrhoids, enuresis, and dryness of the throat.
(Because the Chong and Ren Mai ascend from the lower abdomen to the throat, and the Du Mai follows the genitalia, converges at the Zuanjian, winds around the posterior Zuan, and diverges around the buttocks, symptoms include infertility, strangury, hemorrhoids, enuresis, and dry throat. It is called the Ren Mai because women rely on it for nourishment. Hence the *Classic* says: this disease causes infertility in women. It is called the Chong Mai because its Qi rushes upward. Hence the *Classic* says: this disease involves Qi rushing from the lower abdomen to the heart causing pain. It is called the Du Mai because it supervises and leads the Sea of the Meridians. Do these three Yin meridians perhaps interconnect? However, the Ren, Chong, and Du Mai share one source and rise in three branches. The Du Mai travels from Huiyin along the back, the Ren Mai from Huiyin along the abdomen, and the Chong Mai from Qichong along the Foot-Shaoyin. Only the Du Mai originates from Huiyin, which is below the lower abdomen, in the center of the transverse bone. Women enter/connect to the Tingkong, follow the genitalia, converge at the Zuanjian, and from behind the two yins, have collaterals that diverge, wind around the buttock flesh, internally connect to the spine, and belong to the Kidney. The collateral of the Foot-Taiyang Bladder Meridian, from the outer runner, follows the hip pivot and lateral thigh, while its middle runner descends through the buttocks to the pharynx, merging with the outer runner. The Foot-Shaoyin Kidney Meridian ascends from the inner posterior thigh, pierces the spine, and belongs to the Kidney, and together with the Foot-Taiyang starts at the inner canthus, ascends to the forehead, crosses the vertex, enters the brain, exits, descends the neck, follows the shoulder blades, flanks the spine, reaches the waist, enters the paraspinal muscles, and connects to the Kidney, exactly as the Foot-Taiyang meridian travels. Yet, although the Du Mai and Ren Mai have different names, their Qi and pulses are indistinguishable. The pathway traveled by the Du Mai is exactly like the Ren Mai; thus, from the lower abdomen upward, it pierces the umbilicus, ascends through the Heart, enters the throat, ascends to the chin, circles the lips, and connects to the center below the eyes. Pathology of the Du Mai is also like pathology of the Ren Mai: Qi rushing from the lower abdomen to the heart causing pain, inability to pass urine/stool called Chongsan. Diseases occurring in women are exactly like those of the Ren and Chong Mai. Therefore, these meridians intersect and induce disease, using mutual names.)
