开者、司动静之基。阖者执禁固之权。枢者、主动转之微。三经不得相失。今足少阴肾脉已绝。是故一经相失。少阴不

足厥阴气绝。即筋缩引卵与舌卷。厥阴者、肝脉也。肝者、筋之合也。筋者、聚于阴器。而络于舌本。故脉不荣。
则筋缩急。筋缩急。即引卵与舌。故舌卷卵缩。此筋先死。庚日笃。辛日死。
丁曰。足厥阴经者。肝之脉也。属木。王春。气内养于筋。外则上系舌本。下环于阴器。其气绝。则舌卷卵缩。故

手太阴气绝。即皮毛焦。太阴者、肺也。行气温于皮毛者也。气弗荣、则皮毛焦。皮毛焦、则津液去。津液去、即
皮节伤。皮节伤、则皮枯毛折。毛折者。则气先死。丙日笃。丁日死。

手少阴气绝。则脉不通。脉不通。则血不流。血不流。则色泽去。故面黑如梨。此血先死。壬日笃。癸日死。
丁曰。手少阴经者。真心脉也。属君火。王夏。主于荣。通于脉也。其经非不言手厥阴心包络为主相火。相行君命。

三阴气俱绝者。则目眩转目瞑。目瞑者为失志。失志者、则志先死。死即目瞑也。
丁曰。所言三阴者。独是言足三阴也。足少阴者。肾也。肾藏精与志。足厥阴。肝也。肝藏魂。通于目。故绝则失
志而乱。魂去目眩也。杨曰。三阴者、是手足三阴脉也。此五脏之脉也。五脏者、人之根本也。故三阴俱绝。则目瞑。
瞑、闭也。言根绝于内。而华□于外。目者、人之光华也。眩、乱也。言目乱不识人也。肾藏精与志。精气已竭。故曰
失志也。三阴绝。皆止得一日半死也。虞曰。五脏之脉皆属三阴。五脏之脉。皆会于目。今三阴俱绝。故目眩目瞑也。
人之五志皆属于阴。谓肝志怒。心志喜。脾志思。肺志忧。肾志恐。今三阴已绝。五脏皆失其志。故无喜怒忧思恐。五
志俱亡。故曰失志也。杨氏言失志。乃止言肾一脏也。本经曰。阴阳相离则怅然失志。此之谓也。
六阳气俱绝者。则阴与阳相离。阴阳相离。则腠理泄。绝汗乃出。大如贯珠。转出不流。即气先死。旦占夕死。夕
占旦死。
丁曰。所言六阳。是手足三阳也。后言阴与阳相离者。谓手三阳通天气。故曰阳也。足三阳通地气。故云阴也。天
地阴阳痞隔。所以言阴阳相离也。是故腠理泄。绝汗乃出。大如贯珠。故其死不移旦夕也。杨曰。此六阳气绝。不出日

曰。阴阳相离。气位隔绝。腠理开疏。汗乃大出。夫如是。则六阳皆绝。其死明矣。况三阳之脉。亦有离合。太阳为开。
阳明为阖。少阳为枢。开者、司动静之基。阖者、执禁固之权。枢者、明转动之微。三经不得相失。今六阳已绝。失其
动静之司。弛其禁固之枢。止其动转之微。三经相失。故曰死也。六阳者。素问曰。上下经乃成六也。
肾气衰竭，就不能滋养骨髓，所以肌肉松弛萎缩。所谓“却”，就是收缩的意思，指牙龈的肌肉收缩，因此牙齿看起来逐渐变长且干燥枯槁。所谓牙齿干燥、色泽不润泽。肾是津液的主宰，现在没有津液，所以头发失去滋润。戊和己属土，肾属水，土能克水，所以说戊日病情加重，己日死亡。虞氏说：阴阳有少壮之分，所以有三阴三阳，用来通畅气血，滋养人体。因此三阴经有开、阖、枢的关系，太阴为开，厥阴为阖，少阴为枢。开者，掌管动静的基础；阖者，执掌禁固的权力；枢者，主宰转动细微的变化。这三条经脉不能相互脱离。现在足少阴肾脉已经断绝，这就是一条经脉脱离了整体，少阴不能充当枢纽，转动的细微功能不再主导，所以说会死亡。《诊要经终论》说：少阴经气终结时，面色发黑，牙齿显得长且有污垢，腹部胀满闭塞，上下不通而死亡。说的就是这个道理。
足太阴脾经气竭，则脉气不能荣养口唇。口唇是肌肉的根本。脉气不能荣养，则肌肉不滑润光泽。肌肉不滑润光泽，则肌肉肿胀饱满。肌肉肿胀饱满则嘴唇外翻。嘴唇外翻则肌肉先死。甲日病情加重，乙日死亡。
丁氏说：足太阴经是脾的经脉，属土，旺于季夏。其气在内滋养肌肉，在外荣华卫护口唇。其气断绝则嘴唇外翻、肌肉肿胀，所以甲日病情加重，乙日死亡。这是足太阴经气断绝的表现。杨氏说：足太阴是脾脉，脾主肌肉。其气既已断绝，所以肌肉粗糙涩滞且嘴唇外翻。甲和乙属木，脾属土，木能克土，所以说甲日病情加重，乙日死亡。虞氏说：口唇是肌肉的终点，也称为脾的外华。现在嘴唇外翻且颜色发青，是木来贼害土，所以说会死亡。阴阳的开合关系，以太阴为开，即掌管动静的基础。现在脉气已断绝，那么动静的根基就失去了主持，所以说会死亡。《素问》说：太阴经气终结时，腹部胀满闭塞，呼吸不畅，容易呕吐，呕吐则气逆，气逆则面色发红。
足厥阴肝经气绝，则筋脉收缩，牵引睾丸上缩并卷曲舌头。厥阴是肝脉，肝合于筋。筋聚生于阴器，并联络于舌根。所以脉气不能荣养，则筋脉收缩紧急。筋脉收缩紧急，就会牵引睾丸上缩和舌头卷曲，导致舌卷卵缩。这是筋先死。庚日病情加重，辛日死亡。
丁氏说：足厥阴经是肝的经脉，属木，旺于春季。其气在内滋养筋脉，在外向上系连舌根，向下环绕阴器。其气断绝，则舌卷卵缩，所以庚日病情加重，辛日死亡。这是足厥阴经气断绝的表现。杨氏说：足厥阴是肝脉，肝主筋。其气既已断绝，所以筋脉收缩紧急且舌卷卵缩。庚和辛属金，肝属木，金能克木，所以说庚日病情加重，辛日死亡。
手太阴肺经气绝，则皮毛焦枯。太阴是肺，运行气以温煦皮毛。气不能荣养，则皮毛焦枯。皮毛焦枯，则津液耗去。津液耗去，则皮节受损。皮节受损，则皮肤干枯、毛发折断。毛发折断，说明气先死。丙日病情加重，丁日死亡。
丁氏说：手太阴经是肺的经脉，属金，旺于秋季。其气在内主管气，在外荣华皮毛。其气断绝，则津液耗去，皮毛焦枯，所以丙日病情加重，丁日死亡。杨氏说：手太阴是肺脉，肺主行气，所以说温煦皮毛。丙和丁属火，肺属金，火能克金，所以说丙日病情加重，丁日死亡。虞氏说：肺运行卫气以滋养皮毛。现在皮毛焦枯，就知道火来烁金。皮肤干枯、毛发折断、脉气断绝，其离合规律与足太阴相同。
手少阴心经气绝，则脉道不通。脉道不通，则血液不流动。血液不流动，则色泽消退，所以面色黑如梨（黧）。这是血先死。壬日病情加重，癸日死亡。
丁氏说：手少阴经是真心脉，属君火，旺于夏季，主要主管营气，通达于脉。经文不只说手厥阴心包络为主相火，相火执行君主的命令，主要通调营气。现在真心气绝，则营气不行。营气不行，则血液不流行，因此色泽消退，所以面色黑如黧色。壬日病情加重，癸日死亡。这是疾病所致，并非年老体衰。“梨”字应当作“黧”字。杨氏说：经文讲手三阴，这里只解释了太阴和少阴，而没有解释心主这一经，为什么呢？心主是心包络的经脉，少阴是心脉。这两条经脉都候应于心，所以说少阴绝则心主也绝，诊断方法相同，所以不再分别解释。本经说：“面色黑如漆柴。”这里说“如梨”。漆柴是恒山苗，这种草颜色黄黑，无润泽，所以用来比喻。梨是人所食的水果，也取其黄黑色。意思是人如果没有血，颜色就黄黑，像这两种东西一样没有光华。壬和癸属水，心属火，水克火，所以说壬日病情加重，癸日死亡。虞氏说：心主血，血即为营，荣华人体，所以有光华之色。现在脉已断绝，血就不行，所以人气色夭折，面色黑如梨。可知是水来贼害火，其离合规律与足少阴相同。
三阴经气全部断绝，则头晕目眩，眼睛闭合。眼睛闭合是因为失志。失志，就是志先死。死则眼睛闭合。
丁氏说：所说的三阴，专指足三阴。足少阴是肾，肾藏精与志。足厥阴是肝，肝藏魂，通于目。所以气绝则失志而神乱，魂去则目眩。杨氏说：三阴是指手足三阴脉，这是五脏的经脉。五脏是人的根本。所以三阴俱绝，则眼睛闭合。瞑，就是闭。意思是根本在内部断绝，而荣华在外部丧失。眼睛是人的光华所在。眩，就是乱。意思是眼睛混乱，不认识人。肾藏精与志，精气已竭，所以叫失志。三阴绝，只能活一天半就会死亡。虞氏说：五脏的脉都属于三阴。五脏的脉，都会聚于目。现在三阴俱绝，所以目眩目瞑。人的五志都属于阴，即肝志怒，心志喜，脾志思，肺志忧，肾志恐。现在三阴已绝，五脏都失去了其志，所以没有喜怒忧思恐，五志俱亡，所以叫失志。杨氏所说的失志，仅指肾这一脏。本经说：“阴阳相离则怅然失志。”说的就是这个道理。
六阳气全部断绝，则阴与阳分离。阴阳分离，则腠理泄开，绝汗流出，汗珠大如串珠，转动而不流散，这就是气先死。早晨占测晚上死，晚上占测早晨死。
丁氏说：所说的六阳，是手足三阳。后文说阴与阳分离，是指手三阳通天气，所以叫阳；足三阳通地气，所以叫阴。天地阴阳痞塞阻隔，所以说阴阳分离。因此腠理泄开，绝汗流出，大如串珠，所以死亡时间不会超出旦夕之间。杨氏说：这是六阳气绝，不出一日而死。略述六阳气绝的症状：经文说，太阳脉绝，其表现是戴眼、反折、抽搐，面色白，绝汗流出，流出后就终结了。少阳脉绝，其表现是耳聋、全身关节松懈弛纵、眼球固定直视、绝系，绝系后一天半死，如果面色青则死。阳明脉绝，其表现是口耳张开、易惊、胡言乱语、面色黄，如果上下经脉盛满且麻木不仁则终结。这是三阳绝的症状。前文说六阳，现在经文说三阳绝状，是因为手足诸阳脉绝，其绝状都相同，所以不再分别列出。阴与阳相离，是指阴阳隔绝不相朝使。腠理泄开，是因为阳气已下陷，毛孔皆开，所以如此。绝汗，就是汗出如珠，身体出汗附着在肉上，像缀着的珠子而不流散，所以叫贯珠。旦占夕死，夕占旦死者，正好是半天。只有少阳绝得一天半。虞氏说：阴阳分离，气位隔绝，腠理开疏，汗乃大出。如果是这样，则六阳皆绝，其死亡是明显的。况且三阳之脉也有开、阖、枢的关系，太阳为开，阳明为阖，少阳为枢。开者，掌管动静的基础；阖者，执掌禁固的权力；枢者，明察转动细微的变化。这三条经脉不能相互脱离。现在六阳已绝，失去了动静的主持，松弛了禁固的枢纽，停止了转动的细微变化。三经相互脱离，所以说会死亡。六阳，《素问》说：上下经合起来成为六。
When the Kidney Qi (Kidney Energy) is exhausted, it cannot nourish the bone marrow. Therefore, the flesh becomes flaccid and retracts. "Retract" means contraction; it refers to the contraction of the gingival flesh, causing the teeth to appear gradually longer and become dry and withered. Dryness of the teeth indicates a lack of luster. The Kidney is the master of body fluids (Jin-Ye). Now that there are no body fluids, the hair loses its moisture. Wu and Ji belong to Earth, while the Kidney belongs to Water. Earth overcomes Water; therefore, it is said that the condition worsens on Wu days and death occurs on Ji days. Yu stated: Yin and Yang have stages of youth and maturity, hence there are three Yin and three Yang channels to circulate Qi and Blood and nourish the human body. Thus, the three Yin channels have the functions of Opening (Kai), Closing (He), and Pivot (Shu). The Taiyin serves as the Opening, the Jueyin as the Closing, and the Shaoyin as the Pivot. The Opening governs the foundation of movement and stillness; the Closing holds the authority of restriction; the Pivot manages the subtleties of rotation and transformation. These three channels must not be separated from one another. Now that the Foot-Shaoyin Kidney channel has ceased, one channel has been lost. Since the Shaoyin cannot function as the Pivot, the subtleties of movement and rotation are no longer dominant, hence it is said that death will occur. The *Zhenyao Jingzhong Lun* states: "When the Shaoyin ends, the face turns black, the teeth appear long and dirty, the abdomen is distended and closed, and there is no communication between the upper and lower parts, leading to death." This is what is meant.
When the Qi of the Foot-Taiyin Spleen channel ceases, the vessels fail to nourish the lips. The lips are the root of the muscles. If the vessels do not nourish, the muscles lose their smoothness and luster. If the muscles lack luster, they become full and swollen. When the muscles are full, the lips evert. When the lips evert, the flesh dies first. The condition worsens on Jia days, and death occurs on Yi days.
Ding stated: The Foot-Taiyin channel is the Spleen vessel, belonging to Earth, and is prosperous in the late summer. Its Qi internally nourishes the muscles and externally protects and manifests in the lips. When its Qi ceases, the lips evert and the muscles become full; thus, the condition worsens on Jia days and death occurs on Yi days. This is the manifestation of the cessation of the Foot-Taiyin Qi. Yang stated: The Foot-Taiyin is the Spleen vessel; the Spleen governs the muscles. Since its Qi has ceased, the muscles become rough and coarse, and the lips evert. Jia and Yi belong to Wood, while the Spleen belongs to Earth. Wood overcomes Earth; therefore, it is said that the condition worsens on Jia days and death occurs on Yi days. Yu stated: The lips are the termination of the flesh and are also called the external manifestation of the Spleen. Now, with everted lips and a bluish color, Wood is attacking Earth; therefore, it is said that death will occur. Regarding the separation and combination of Yin and Yang, the Taiyin serves as the Opening, governing the foundation of movement and stillness. Now that the vessel Qi has ceased, the foundation of movement and stillness has lost its governance, hence it is said that death will occur. The *Suwen* states: "When the Taiyin ends, there is abdominal distension and closure, difficulty breathing, frequent vomiting, reversal of Qi upon vomiting, and redness of the face due to reversal."
When the Qi of the Foot-Jueyin Liver channel ceases, the sinews contract, pulling the testicles upward and curling the tongue. Jueyin is the Liver vessel; the Liver harmonizes with the sinews. The sinews gather at the genital organs and connect to the base of the tongue. Therefore, if the vessels do not nourish, the sinews contract and tighten. Tightened sinews pull the testicles and tongue, resulting in a curled tongue and retracted testicles. This indicates that the sinews die first. The condition worsens on Geng days, and death occurs on Xin days.
Ding stated: The Foot-Jueyin channel is the Liver vessel, belonging to Wood, and is prosperous in spring. Its Qi internally nourishes the sinews and externally connects upward to the base of the tongue and circles downward around the genital organs. When its Qi ceases, the tongue curls and the testicles retract; thus, the condition worsens on Geng days and death occurs on Xin days. This is the manifestation of the cessation of the Foot-Jueyin Qi. Yang stated: The Foot-Jueyin is the Liver vessel; the Liver governs the sinews. Since its Qi has ceased, the sinews contract and tighten, resulting in a curled tongue and retracted testicles. Geng and Xin belong to Metal, while the Liver belongs to Wood. Metal overcomes Wood; therefore, it is said that the condition worsens on Geng days and death occurs on Xin days.
When the Qi of the Hand-Taiyin Lung channel ceases, the skin and hair become scorched and dry. Taiyin is the Lung, which circulates Qi to warm the skin and hair. If Qi does not nourish, the skin and hair become scorched. If the skin and hair are scorched, body fluids are depleted. If body fluids are depleted, the skin joints are damaged. If the skin joints are damaged, the skin becomes withered and the hair breaks. Hair breaking indicates that Qi dies first. The condition worsens on Bing days, and death occurs on Ding days.
Ding stated: The Hand-Taiyin channel is the Lung vessel, belonging to Metal, and is prosperous in autumn. Its Qi internally governs Qi and externally nourishes the skin and hair. When its Qi ceases, body fluids are depleted, and the skin and hair become scorched; thus, the condition worsens on Bing days and death occurs on Ding days. Yang stated: The Hand-Taiyin is the Lung vessel; the Lung governs the circulation of Qi, hence it warms the skin and hair. Bing and Ding belong to Fire, while the Lung belongs to Metal. Fire overcomes Metal; therefore, it is said that the condition worsens on Bing days and death occurs on Ding days. Yu stated: The Lung circulates Defensive Qi (Wei-Qi) to nourish the skin and hair. Now that the skin and hair are scorched, it is known that Fire is scorching Metal. Withered skin, broken hair, and ceased vessels follow the same principles of separation and combination as the Foot-Taiyin.
When the Qi of the Hand-Shaoyin Heart channel ceases, the vessels become blocked. If the vessels are blocked, Blood does not flow. If Blood does not flow, luster disappears, so the face turns black like a pear (li). This indicates that Blood dies first. The condition worsens on Ren days, and death occurs on Gui days.
Ding stated: The Hand-Shaoyin channel is the True Heart vessel, belonging to Ministerial Fire (Jun-Huo), and is prosperous in summer. It primarily governs Nutritive Qi (Ying-Qi) and connects to the vessels. The text does not explicitly mention the Hand-Jueyin Pericardium as the primary Ministerial Fire (Xiang-Huo); Ministerial Fire executes the orders of the Sovereign Fire and primarily regulates Nutritive Qi. Now that the True Heart Qi has ceased, Nutritive Qi does not circulate. If Nutritive Qi does not circulate, Blood does not flow freely, hence luster disappears, and the face turns black like dark earth (ni). The condition worsens on Ren days and death occurs on Gui days. This is due to disease, not old age. The character "pear" (li) should be read as "dark earth" (ni). Yang stated: The classic discusses the Three Yin channels of the hand, but here only the Taiyin and Shaoyin are explained, while the Heart Master (Heart Governor) channel is not mentioned. Why? The Heart Master is the Pericardium vessel, and the Shaoyin is the Heart vessel. Both channels correspond to the Heart. Therefore, when the Shaoyin ceases, the Heart Master also ceases. Since the diagnosis is the same, it is not explained separately. The original classic states: "The face turns black like lacquered charcoal." Here it says "like a pear." Lacquered charcoal refers to the seedling of *Dichroa febrifuga*, which is yellow-black and lacks luster, used here as a metaphor. A pear is a fruit eaten by humans, also taken for its yellow-black color. It means that without blood, the complexion is yellow-black, lacking the luster of these two objects. Ren and Gui belong to Water, while the Heart belongs to Fire. Water overcomes Fire; therefore, it is said that the condition worsens on Ren days and death occurs on Gui days. Yu stated: The Heart governs Blood, and Blood is Nutritive Qi, which nourishes the human body and provides luster. Now that the vessels have ceased, Blood does not flow, so the person's vitality fades, and the face turns black like a pear. This shows that Water is attacking Fire, and the principle of separation and combination is the same as the Foot-Shaoyin.
When the Qi of all three Yin channels ceases, dizziness and spinning sensations occur, and the eyes close. Eye closing is due to the loss of Will (Zhi). Loss of Will means the Will dies first. Death results in eye closing.
Ding stated: The "three Yin" mentioned refers specifically to the Foot-Three Yin channels. The Foot-Shaoyin is the Kidney, which stores Essence and Will. The Foot-Jueyin is the Liver, which stores the Soul (Hun) and connects to the eyes. Therefore, when Qi ceases, the Will is lost and chaotic, and the Soul departs, causing dizziness. Yang stated: The three Yin refer to the Three Yin channels of both hands and feet, which are the vessels of the Five Zang organs. The Five Zang organs are the root of humanity. Therefore, when all three Yin cease, the eyes close. "Ming" means closing. It means the root is severed internally, and the external manifestations are lost. The eyes are the brilliance of the human body. "Xuan" means disorder. It means the eyes are disordered and cannot recognize people. The Kidney stores Essence and Will; since Essence and Qi are exhausted, it is called loss of Will. When the three Yin cease, death occurs within one and a half days. Yu stated: The vessels of the Five Zang organs all belong to the three Yin. The vessels of the Five Zang organs converge at the eyes. Now that all three Yin have ceased, there is dizziness and eye closing. The five mental activities (Wu-Zhi) of humans all belong to Yin: anger belongs to the Liver, joy to the Heart, thought to the Spleen, sorrow to the Lung, and fear to the Kidney. Now that the three Yin have ceased, the Five Zang organs have lost their respective mental activities, so there is no anger, joy, sorrow, thought, or fear. With all five mental activities perished, it is called loss of Will. Yang's statement on loss of Will referred only to the Kidney organ. The original classic states: "When Yin and Yang separate, one feels bereft and loses their Will." This is what is meant.
When the Qi of all six Yang channels ceases, Yin and Yang separate. When Yin and Yang separate, the interstices (Cou-Li) leak, and absolute sweat (Jue-Han) emerges. The sweat drops are large like beads strung together, turning but not flowing. This indicates that Qi dies first. One predicted in the morning dies in the evening; one predicted in the evening dies in the morning.
Ding stated: The "six Yang" refers to the Three Yang channels of both hands and feet. The subsequent mention of Yin and Yang separating refers to the Hand-Three Yang connecting to Heaven Qi, hence called Yang; and the Foot-Three Yang connecting to Earth Qi, hence called Yin. The blockage and separation of Heaven and Earth Yin and Yang result in the statement that Yin and Yang separate. Therefore, the interstices leak, and absolute sweat emerges, large like beads, so death will not exceed morning or evening. Yang stated: This describes the cessation of Six Yang Qi, leading to death within a day. The symptoms of Six Yang Qi cessation are briefly listed below. The classic states: "When the Taiyang vessel ceases," the symptoms are staring upward (Dai-Yan), opisthotonos (Fan-Zhe), convulsions (Chou-Chu), white complexion, and emergence of absolute sweat. Once the sweat emerges, life ends. "When the Shaoyang vessel ceases," the symptoms are deafness, complete relaxation of all joints, fixed staring eyes, and severance of the connection. Severance leads to death in one and a half days; if the complexion is green, death occurs. "When the Yangming vessel ceases," the symptoms are gaping of the mouth and ears, fright, delirious speech, yellow complexion, and if the upper and lower vessels are full yet insensitive, life ends. These are the symptoms of the cessation of the Three Yang channels. The earlier text mentions Six Yang, while the current text describes the cessation of the Three Yang because the cessation symptoms of all hand and foot Yang vessels are identical, so they are not listed separately. "Yin and Yang separating" means Yin and Yang are isolated and do not interact. "Interstices leaking" means Yang Qi has sunk and the pores are all open, which is why this happens. "Absolute sweat" refers to sweat emerging like beads, adhering to the flesh like attached pearls without flowing away, hence called "beads strung together." "Predicted in the morning, dying in the evening; predicted in the evening, dying in the morning" refers to a period of half a day. Only the cessation of Shaoyang allows for one and a half days. Yu stated: When Yin and Yang separate, Qi positions are isolated, and the interstices become loose and open, causing massive sweating. In such a case, all Six Yang channels have ceased, and death is evident. Moreover, the Three Yang channels also have the functions of Opening, Closing, and Pivot. The Taiyang serves as the Opening, the Yangming as the Closing, and the Shaoyang as the Pivot. The Opening governs the foundation of movement and stillness; the Closing holds the authority of restriction; the Pivot manages the subtleties of rotation and transformation. These three channels must not be separated. Now that all Six Yang channels have ceased, the governance of movement and stillness is lost, the authority of restriction is relaxed, and the subtleties of rotation and transformation stop. The three channels are separated from each other, hence it is said that death will occur. Regarding the Six Yang, the *Suwen* states: Upper and lower vessels combine to form six.
