足少阴之正，至 中，别走太阳心而合，上至肾，当十四椎，出属带脉。（《八十一难》云∶
带脉起于季胁，为回身一周。既言一周，亦周腰脊也，故带脉当十四椎，束带腰腹，故曰带脉也。
平按∶太阳下《灵枢》、《甲乙经》均无心字。当字上半为虫蚀，只剩下半田字，据《灵枢》、
《甲乙经》及本注应作当。椎《灵枢》作 。注季胁袁刻作季肋，原抄及难经均作胁。又束带腰
腹袁刻作束腰带腹。）
阳明者，五脏六腑之海也，主润宗筋。宗筋者，束肉骨而利机关。（阳明主于水谷，故为脏
腑之海，能润宗筋，约束骨肉，利诸机关也。平按∶束肉骨《素问》、《甲乙经》均作主束骨。）
冲脉者，经脉之海
也，主渗灌溪谷，（阳明以为脏腑海。冲脉血气壮盛，故为经脉之海，主渗灌骨肉会处，益其血
气。）与阳明合于筋阴，总宗筋之会，会于气街，而阳明为之长，皆属于带脉而络于督脉。（冲
脉与阳明二脉合于阴器，总聚于宗筋，宗筋即二核及茎也，复会于左右气街，以左右阳明为主，
共属带脉，仍络于督脉，以带脉为控带也。平按∶筋阴《素问》、《甲乙经》作宗筋阴阳四字。
气街《甲乙经》作气冲。）故阳明虚则宗筋纵，带脉不引，故足痿不用。（阳明谷气虚少，则宗筋
之茎施纵，带脉不为牵引，则筋脉施舒，故足痿。）
平按：本篇从篇首至“属带脉”的内容，见于《灵枢》卷三第十一《经别》篇，又见于《甲乙经》卷二第一下编，又见于本书卷九《经脉正别》篇。从“自阳明者”至末尾的内容，见于《素问》卷十二第四十四《痿论》篇，又见于《甲乙经》卷十第四。
足少阴之正（足少阴肾经的正经），上行至腘窝中，分支走向太阳经和心经并相合，上行至肾脏，在第十四椎处，外出归属于带脉。（《八十一难经》说：带脉起始于季胁，环绕身体一周。既然说是环绕一周，也是环绕腰脊，所以带脉位于第十四椎，像束带一样约束腰腹，因此称为带脉。）
【平按】：《灵枢》、《甲乙经》中“太阳”下没有“心”字。“当”字上半部分被虫蛀蚀，只剩下下半部分的“田”字，根据《灵枢》、《甲乙经》及本注应作“当”。《灵枢》中“椎”写作特定异体字。注释中“季胁”，袁刻本作“季肋”，原抄本及《难经》均作“胁”。另外，“束带腰腹”，袁刻本作“束腰带腹”。
阳明胃经，是五脏六腑的海，主要滋润宗筋（众多筋脉的总称）。宗筋，是约束肌肉骨骼并使关节活动灵活的部位。（阳明胃主受纳水谷，所以是脏腑之海，能滋润宗筋，约束骨肉，使各种关节灵活。【平按】：“束肉骨”，《素问》、《甲乙经》均作“主束骨”。）
冲脉，是经脉的海，主要渗透灌溉溪谷（肌肉间的间隙）。（阳明为脏腑之海。冲脉血气壮盛，所以是经脉之海，主要渗透灌溉骨肉交会之处，补充其血气。）冲脉与阳明经会合于阴部，总聚于宗筋的会合处，会合于气街（穴名，指腹股沟动脉搏动处），而阳明经作为主导，都归属于带脉并联络于督脉。（冲脉与阳明经两脉会合于阴器，总聚于宗筋，宗筋即睾丸及阴茎，又会在左右气街，以左右的阳明经为主，共同属于带脉，仍然联络于督脉，因为带脉起控制束带的作用。【平按】：“筋阴”，《素问》、《甲乙经》作“宗筋阴阳”四字。“气街”，《甲乙经》作“气冲”。）所以阳明经虚弱则宗筋弛纵，带脉不能牵引，所以足部痿废不能使用。（阳明谷气虚少，则宗筋松弛，带脉不为牵引，则筋脉舒展，所以足部痿废。）
Ping An: The content from the beginning of this chapter to "attaching to the Dai Mai (Girdle Vessel)" is found in Chapter 11 "Jing Bie" (Divergent Channels) of Volume 3 of *Ling Shu* (Spiritual Pivot), also in the First Lower Section of Volume 2 of *Jia Yi Jing* (Systematic Classic of Acupuncture and Moxibustion), and also in Chapter 9 "Jing Mai Zheng Bie" (Regular and Divergent Meridians) of this book. The content from "Yang Ming" to the end is found in Chapter 44 "Wei Lun" (Discourse on Flaccidity) of Volume 12 of *Su Wen* (Basic Questions), and also in Chapter 4 of Volume 10 of *Jia Yi Jing*.
The regular pathway of Foot-Shaoyin (Kidney Meridian) ascends to the popliteal fossa, branches off to connect with Taiyang (Bladder Meridian) and the Heart, and merges; it then ascends to the Kidney, exits at the level of the fourteenth thoracic vertebra, and attaches to the Dai Mai (Girdle Vessel). (*Nan Jing* [Classic of Difficult Issues] states: The Dai Mai originates from the costal margin and encircles the body once. Since it is said to encircle once, it also encircles the waist and spine; thus, the Dai Mai is located at the fourteenth vertebra, binding the waist and abdomen like a belt, hence named Dai Mai.)
[Ping An: In *Ling Shu* and *Jia Yi Jing*, the character "Xin" (Heart) after "Taiyang" is absent. The upper part of the character "Dang" (at/level of) is eaten by insects, leaving only the lower half resembling "Tian"; based on *Ling Shu*, *Jia Yi Jing*, and this commentary, it should be read as "Dang". *Ling Shu* writes "Zhui" (vertebra) differently. In the commentary, "Ji Xie" (costal margin) is printed as "Ji Lu" in Yuan's edition, while the original manuscript and *Nan Jing* both use "Xie". Additionally, "Shu Dai Yao Fu" (bind belt waist abdomen) is printed as "Shu Dai Yao Dai Fu" in Yuan's edition.]
Yang Ming (Stomach Meridian) is the sea of the five Zang and six Fu organs, primarily moistening the Zong Jin (Major Confluence of Sinews). Zong Jin binds muscles and bones and facilitates joint movement. (Yang Ming governs water and grain, thus serving as the sea of the Zang and Fu organs; it can moisten Zong Jin, constrain bone and flesh, and facilitate various joints.) [Ping An: "Shu Rou Gu" (bind muscle bone) in *Su Wen* and *Jia Yi Jing* is written as "Zhu Shu Gu" (mainly bind bone).]
Chong Mai (Penetrating Vessel) is the sea of the meridians, primarily seeping and irrigating the Xi Gu (valleys/clefts between muscles). (Yang Ming is the sea of the Zang and Fu organs. Chong Mai has vigorous Qi and Blood, thus becoming the sea of the meridians; it primarily seeps and irrigates places where bone and flesh meet, benefiting their Qi and Blood.) It combines with Yang Ming at the Yin region, gathering at the confluence of Zong Jin, meeting at Qi Jie (Street of Qi, referring to the inguinal region), with Yang Ming acting as the leader; all belong to Dai Mai and network with Du Mai (Governor Vessel). (Chong Mai and Yang Ming merge at the genitalia, gathering at Zong Jin, which refers to the testes and penis; they again meet at the left and right Qi Jie, dominated by the left and right Yang Ming, collectively belonging to Dai Mai, and still networking with Du Mai, because Dai Mai acts as a controlling belt.) [Ping An: "Jin Yin" (Sinew Yin) in *Su Wen* and *Jia Yi Jing* is written as "Zong Jin Yin Yang" (Four characters: Major Confluence of Sinews Yin Yang). "Qi Jie" in *Jia Yi Jing* is written as "Qi Chong".] Therefore, when Yang Ming is deficient, Zong Jin becomes flaccid, and Dai Mai fails to pull, resulting in foot Wei (flaccidity) and inability to use the legs. (When Grain Qi of Yang Ming is deficient, the sinews of Zong Jin become lax, Dai Mai does not provide traction, sinews and vessels relax, thus causing foot flaccidity.)
