问曰∶寸口脉沉大而滑，沉则为实，滑则为气，实气相搏，气血入脏即死，入腑即愈，此谓卒
厥，何谓也？
师曰∶唇口青，身冷，为入脏，即死；身和，汗自出，为入腑，即愈。
问曰∶脉脱入脏即死，入腑即愈，何谓也？师曰∶非为一病，百病皆然。譬如浸淫疮，从口起流向
四肢者可治，从四肢流来入口者不可治。病在外者可治，入里者即死。
五邪中人，各有法度，风中于前，寒中于暮，湿伤于下，雾伤于上。风令脉浮，寒令脉急。雾
伤皮腠，湿流关节，食伤脾胃，极寒伤经，极热伤络。
夫男子平人，脉大为劳，极虚亦为劳。男子脉浮弱而涩为无子，精气清冷。脉得诸芤动微紧，
男子失精，女子梦交。
男子平人，脉虚弱细微者，喜盗汗也。脉沉小迟名脱气，其人疾行则喘喝，手足逆寒，腹满，
甚则溏泄，食不消化也。脉弦而大，弦则为减，大则为芤，减则为寒，芤则为虚，虚寒相搏，此名
为革，妇人则半产漏下，男子则亡血失精。
凡诊脉，先须识时脉、胃脉与脏腑平脉，然后及于病脉。时脉谓春三月六部中俱带弦，夏三月
俱带洪，秋三月俱带浮，冬三月俱带沉。胃脉谓中按得之，脉见和缓。凡人脏腑胃脉既平，又应时
脉，乃无病者也，反此为病。
持脉之要有三，曰举，曰按，曰寻。轻手循之曰举，重手取之曰按，不轻不重，委曲求之曰寻。
初持脉，轻手候之，脉见皮肤之间者，阳也，腑也，亦心肺之应也。重手得之，脉附于肉下者，阴
也，脏也，亦肝肾之应也。不轻不重，中而取之，其脉应于血肉之间者，阴阳相适，中和之应，脾
胃之候也。若委曲寻之而若隐若
见，则阴阳伏匿之脉也。
问：寸口脉象沉大而滑，沉脉主里实，滑脉主气盛，实邪与气机相互搏结，如果气血内陷进入脏就会死亡，进入腑就能痊愈，这叫做卒厥，这是什么意思呢？
老师回答说：如果患者嘴唇和口唇发青，身体冰冷，这是病邪入脏的表现，就会死亡；如果身体温和，汗液自然流出，这是病邪入腑的表现，就能痊愈。
问：脉象突然伏匿（脉脱），入脏即死，入腑即愈，这是什么意思呢？
老师说：这并不是针对某一种疾病而言，各种疾病都是这样的道理。譬如浸淫疮，从口部开始向四肢蔓延的可以治疗，从四肢蔓延回入口部的则不可治疗。病邪在体表的可以治疗，深入体内的就会死亡。
五种邪气侵袭人体，各有其规律：风邪多在午前伤人，寒邪多在傍晚伤人，湿邪多损伤下部，雾邪多损伤上部。风邪使脉象浮，寒邪使脉象紧急。雾邪损伤皮肤腠理，湿邪流注关节，饮食不节损伤脾胃，极寒损伤经脉，极热损伤络脉。
男子身体健康者，脉象大是劳损之象，极度虚弱也是劳损之象。男子脉象浮弱而涩，表示无子嗣，精气清冷。脉象出现芤、动、微、紧等特征，男子表现为失精，女子表现为梦交。
男子身体健康者，脉象虚弱细微的，容易患盗汗症。脉象沉小迟称为脱气，这类人快速行走时会气喘吁吁，手足逆冷，腹部胀满，严重时会有溏泄，食物不能消化。脉象弦而大，弦脉表示阳气衰减，大脉表示中空如芤，衰减则为寒，中空则为虚，虚与寒相互搏结，这种脉象称为革脉，妇人会出现半产（流产）及漏下（崩漏），男子会出现亡血及失精。
凡诊察脉象，必须先识别时脉、胃脉以及脏腑的平脉（正常脉象），然后才能辨别病脉。时脉是指春季三个月六部脉都带有弦象，夏季三个月都带有洪象，秋季三个月都带有浮象，冬季三个月都带有沉象。胃脉是指中取时，脉象呈现和缓之象。凡是人的脏腑胃脉平和，又符合时令脉象，就是没有生病的人，与此相反的就是有病。
持脉的要领有三点，叫作举、按、寻。轻手接触皮肤循摸叫作举，重手按压取脉叫作按，不轻不重，仔细探寻叫作寻。初诊脉时，轻手候之，脉象显现于皮肤之间的，属于阳，属于腑，也是心肺的应象。重手得之，脉象依附于肌肉之下的，属于阴，属于脏，也是肝肾的应象。不轻不重，中等力度取之，脉象应于血肉之间的，是阴阳相适，中和的应象，是脾胃的征候。如果仔细探寻而脉象若隐若现，则是阴阳伏匿的脉象。
Question: The pulse at the Cun Kou (Inch Port) is deep, large, and slippery. A deep pulse indicates excess [solidity], and a slippery pulse indicates qi [prosperity/excess]. When excess and qi contend with each other, if qi and blood enter the Zang organs, death ensues; if they enter the Fu organs, recovery occurs. This is called sudden syncope (Cu Jue). What does this mean?
The Master replied: If the lips and mouth are cyanotic and the body is cold, it indicates entry into the Zang organs, leading to death. If the body is harmonious/warm and sweat issues spontaneously, it indicates entry into the Fu organs, leading to recovery.
Question: Regarding the pulse disappearing [suddenly vanishing or deep hiding] where entry into Zang leads to death and entry into Fu leads to recovery, what does this mean?
The Master said: This does not apply to only one disease; all diseases follow this principle. For example, in impetigo-like sores (Jin Yin Chuang), if the lesion starts from the mouth and flows toward the limbs, it is treatable; if it starts from the limbs and flows back to the mouth, it is untreatable. Diseases remaining on the exterior are treatable; those entering the interior lead to death.
The five pathogenic factors attacking humans have their respective patterns: Wind attacks in the morning, Cold attacks in the evening, Dampness injures the lower part, and Fog injures the upper part. Wind causes the pulse to be floating; Cold causes the pulse to be tight/urgent. Fog injures the skin and interstices; Dampness flows into the joints; Food stagnation injures the Spleen and Stomach; Extreme Cold injures the Channels; Extreme Heat injures the Collaterals.
In a healthy man, a large pulse indicates consumption/labor (Lao); extreme deficiency also indicates consumption. In men, a floating, weak, and choppy pulse indicates infertility due to clear and cold essence. A pulse presenting with Kong (scallion-stalk), Dong (agitated), Wei (faint), or Jin (tight) characteristics indicates seminal emission in men and nocturnal intercourse dreams in women.
In a healthy man, a weak, deficient, and fine pulse predisposes to night sweats. A deep, small, and slow pulse is named Qi Depletion (Tuo Qi); such individuals pant heavily when walking quickly, experience cold extremities, abdominal fullness, and in severe cases, loose stools and indigestion. A wiry and large pulse: wiry indicates decline/reduction, large indicates hollow like Kong. Decline implies Cold, hollow implies Deficiency. The contention of Deficiency and Cold is named Ge (Leather) pulse. In women, this manifests as spontaneous abortion and uterine bleeding; in men, it manifests as blood loss and seminal emission.
In general, pulse diagnosis requires first understanding the Seasonal Pulse (Shi Mai), Stomach Pulse (Wei Mai), and the Normal Pulses of the Zang-Fu organs, before proceeding to pathological pulses. Seasonal pulses refer to the six positions all exhibiting a Wiry (Xuan) quality in spring, a Surging (Hong) quality in summer, a Floating (Fu) quality in autumn, and a Deep (Chen) quality in winter. The Stomach Pulse refers to a harmonious and moderate quality felt at medium pressure. When a person's Zang-Fu and Stomach pulses are balanced and correspond to the seasonal pulse, they are disease-free; deviation from this indicates disease.
There are three essentials in holding the pulse: Ju (Lifting), An (Pressing), and Xun (Searching). Lightly touching the surface is Ju; pressing heavily to obtain the pulse is An; neither light nor heavy, seeking carefully through the layers is Xun. Upon initially holding the pulse, if the pulse is felt lightly at the skin level, it is Yang, pertains to the Fu organs, and corresponds to the Heart and Lung. If obtained with heavy pressure, attached beneath the muscle, it is Yin, pertains to the Zang organs, and corresponds to the Liver and Kidney. At medium pressure, felt between flesh and blood, it represents the harmony of Yin and Yang, the Zhong He (Neutral Harmony) response, corresponding to the Spleen and Stomach. If searching carefully reveals the pulse as faint or intermittent, it indicates hidden Yin and Yang.
