不然。天雨降下，沟渠溢满，当此之时， 霈妄行，圣人不能复图也。此络脉满溢，诸经不

小指外侧端的至阴穴，位于足小趾外侧；本节后方的凹陷处是通谷穴。束骨穴在足第五跖骨关节后的凹陷中取穴；京骨穴在足第五跖骨粗隆下方的肉际处寻找。阳跷脉的申脉穴位于外踝下方；承山穴在小肠经循行路线的下方取穴（注：原文“兑 肠”疑为衍文或误植，结合上下文及穴位定位，此处指承山穴位置）；承筋穴在小肠经循行路线的中央。合阳穴在委中穴下一寸，委中穴在腘横纹的中点处。委阳穴在外侧两筋之间的凹陷处，浮郄穴在阳陵泉上一寸处（注：原文“浮在阳一寸上”表述较为简略，通常指浮郄穴位于委阳上方或阳陵泉附近，此处依原文直译并保留原意）。殷门穴在大腿后侧上部，承扶穴在臀部下方，阴冲止（注：原文“阴冲止”语义不明，可能为传抄错误，暂按字面意思处理，指该区域界限）。
《难经》说：脉有奇经八脉，不局限于十二正经，这是什么意思呢？回答说：有阳维脉、阴维脉、阳跷脉、阴跷脉等，络脉有十五条。总共二十七气上下相随运行，为什么唯独不拘限于十二经脉呢？回答说，圣人规划设置沟渠，以通畅水道，以备不时之需。天降雨水，沟渠溢满，此时雨水泛滥妄行，即使是圣人也不能再重新规划了。这就像络脉满溢，诸经就不能再拘束它一样。既然不拘限于十二经络，它们究竟从何而起、由何接续，详见下文。
督脉起自下极（长强穴），并与脊里上行至风府穴，过脑、额、鼻，入内交（注：原文“入 交”缺字，通常指入络脑或交会于巅顶），为阳脉之海的总纲要。任脉起于中极穴之下，与少阴肾经并行，任脉和督脉均起源于会阴穴，这三条脉共同起始而路径不同。阳跷脉起自足跟底部，沿外踝向上进入风池穴。阴跷脉沿内踝上行经过喉嗌，本是阴阳脉的别支。诸阴脉会合于阴维脉，发源于足少阴肾经的筑宾穴。诸阳脉会合于阳维脉，太阳膀胱经的金门穴是其起点。带脉环绕季胁之间，会合于足少阳胆经的维道穴。所谓奇经的八脉维系着诸经，使之顺常运行。
公孙穴属冲脉，主治胃、心、胸部的疾病；内关穴属阴维脉，二者在下部总同。临泣穴属胆经，连带脉；阳维脉在目锐眦（外眼角）处与外关穴相逢。后溪穴属督脉，内颈（注：原文“后 督脉内 颈”缺字，通常指后溪通督脉，治疗颈部病症）；申脉穴属阳跷脉，络脉也相通。列缺穴属任脉，行于肺系；阴跷脉的照海穴主治膈部和喉咙的疾病。
乾卦对应公孙穴，艮卦对应内关穴，巽卦对应震位的外关穴。离卦居列缺穴，坤卦对应照海穴，后溪穴在兑卦和坎卦的申脉穴之间（注：此处八卦配穴歌诀较为晦涩，依原文直译）。补泻手法通过浮沉来区分逆顺，把握时机配合呼吸并不难。这是祖传的秘诀神针法，万病如同拈取般容易治愈。
The Zhiyin (Bladder 67) acupoint is located at the lateral side of the little finger (toe); Tonggu (Bladder 65) is found in the depression behind the metatarsophalangeal joint. Shugu (Bladder 64) is sought in the depression behind the fifth metatarsophalangeal joint; Jinggu (Bladder 64) is located at the muscle-bone junction below the prominence of the fifth metatarsal bone. Shenmai (Bladder 62), belonging to the Yang Qiao Mai (Yang Heel Vessel), is located below the lateral malleolus; Chengshan (Bladder 57) is taken below the pathway of the Intestine Meridian (Note: Text "Dui Chang" is likely an error, referring to location relative to bladder/intestine meridian path); Chengjin (Bladder 57) is in the center of the same pathway. Heyang (Bladder 38) is one cun below Weizhong (Bladder 40); Weizhong is located in the middle of the popliteal crease. Weiyang (Bladder 39) is between the two tendons on the lateral side; Fuyang (Bladder 59) is one cun above Yanglingquan (Gallbladder 34) (Note: Text "Fu zai yang yi cun shang" is concise, generally referring to Fuyang). Yinmen (Bladder 37) is six cun above [reference point] on the upper posterior thigh; Chengfu (Bladder 36) is below the buttock, ending at Yinchong (Note: "Yin chong zhi" is unclear, possibly a transcription error, treated literally as the boundary area).
The *Nan Jing* (Classic of Difficult Issues) states: There are eight extraordinary vessels among the meridians, which are not restricted to the twelve regular meridians. What does this mean? The answer is: There are Yang Wei Mai (Yang Linking Vessel), Yin Wei Mai (Yin Linking Vessel), Yang Qiao Mai (Yang Heel Vessel), and Yin Qiao Mai (Yin Heel Vessel), along with fifteen collateral vessels. In total, twenty-seven Qi circulate up and down together. Why are they uniquely not restricted to the meridians? The answer is that sages planned and dug channels to facilitate water flow, preparing for emergencies. When rain falls from heaven and channels overflow, causing waters to flood wildly, even a sage cannot redraw the plans. This is analogous to when collateral vessels are full and overflowing, the regular meridians can no longer restrain them. Since they are not restricted to the twelve regular meridians, where do these extraordinary vessels originate and continue? See the following text for details.
Du Mai (Governor Vessel) originates from Xiaji (Changqiang, Du 1), ascends within the spinal column to Fengfu (Du 16), passes through the brain, forehead, and nose, entering and intersecting [missing character, usually implying connection to the head/brain], serving as the general outline of the Sea of Yang Vessels. Ren Mai (Conception Vessel) originates below Zhongji (Ren 3), runs parallel with the Kidney Meridian of Foot-Shaoyin. Ren Mai and Du Mai both originate from Huiyin (Ren 1); these three vessels start together but diverge in their paths. Yang Qiao Mai originates from the bottom of the heel, follows the lateral malleolus upward into Fengchi (GB 20). Yin Qiao Mai follows the medial malleolus upward through the throat; it is originally a branch of the Yin and Yang vessels. All Yin vessels converge at Yin Wei Mai, originating from Zhubin (KI 9) of the Foot-Shaoyin Kidney Meridian. All Yang vessels converge at Yang Wei Mai, with Jinmen (BL 63) of the Foot-Taiyang Bladder Meridian as its starting point. Dai Mai (Girdle Vessel) circles around the hypochondrium, converging at Weidao (GB 27) of the Foot-Shaoyang Gallbladder Meridian. These are the eight extraordinary vessels that maintain and regulate the regular meridians, ensuring normal circulation.
Gongsun (SP 4) belongs to Chong Mai (Penetrating Vessel), treating diseases of the Stomach, Heart, and Chest; Neiguan (PC 6) belongs to Yin Wei Mai, sharing similar lower functions. Linqi (GB 41) belongs to the Gallbladder Meridian, connecting with Dai Mai; Yang Wei Mai meets Waiguan (TE 5) at the outer canthus. Houxi (SI 3) belongs to Du Mai, affecting the neck; Shenmai (BL 62) belongs to Yang Qiao Mai, with collaterals also connecting. Lieque (LU 7) belongs to Ren Mai, acting on the Lung system; Zhaohai (KI 6) of Yin Qiao Mai treats disorders of the diaphragm and throat.
Qian trigram corresponds to Gongsun, Gen trigram to Neiguan, Xun trigram corresponds to Zhen position Waiguan. Li trigram is at Lieque, Kun trigram corresponds to Zhaohai, Houxi is between Dui and Kan trigrams' Shenmai (Note: The Bagua-acupoint correspondence here is complex and textual variations exist). Tonification and sedation techniques distinguish reversal and compliance through floating and sinking depths; grasping the timing with respiration is not difficult. This is the ancestral secret divine needle method; myriad diseases are cured as easily as picking something up.
