阴阳者天地之枢机。五行者阴阳之终始。非阴阳则不能为天地。非五行则不能为阴阳。故人者成于天
地。败于阴阳也。由五行逆从而生焉。天地有阴阳五行。人有血脉五脏。五行者金木水火土也。五脏者肺
肝心肾脾也。金生水。水生木。木生火。火生土。土生金。则生成之道。循环无穷。肺生肾。肾生肝。肝生心。心生
脾。脾生肺。上下荣养。无有休息。故金匮至真要论云。心生血。血为肉之母。脾生肉。肉为血之舍。肺属气。气
为骨之基。肾应骨。骨为筋之本。肝系筋筋为血之源。五脏五行。相成相生。昼夜流转。无有始终。从之则吉。
逆之则凶。天地阴阳。五行之道。中含于人。人得者可以出阴阳之数。夺天地之机。悦五行之要。无终无始。
神仙不死矣。
骤风暴热。云物飞扬。晨晦暮晴。夜炎昼冷。应寒不寒。当雨不雨。水竭土坏。时岁大旱。草木枯悴。江河乏涸。
此天地之阳厥也。暴壅塞。忽喘促。四肢不收。二腑不利。耳聋目盲。咽干口焦。舌生疮。鼻流清涕。颊赤心烦。
头昏脑重。双睛似火。一身如烧。素不能者乍能。素不欲者乍欲。登高歌笑。弃衣奔走。狂言妄语。不辨亲疏。
发躁无度。饮水不休胸膈膨胀腹与胁满闷。背疽肉烂。烦溃消中。食不入胃。水不穿肠。骤肿暴满。叫呼。昏
冒。不省人事。疼痛不知去处。此人之阳厥也。阳厥之脉。举按有力者生。绝者死。
阴阳是天地运行的枢纽关键。五行是阴阳变化的终结与起始。如果没有阴阳，就不能形成天地；如果没有五行，阴阳就无法运作。因此，人由天地所生成，却因阴阳失调而败亡，这是由五行顺逆变化而产生的。
天地有阴阳和五行，人有血脉和五脏。五行指的是金、木、水、火、土。五脏指的是肺、肝、心、肾、脾。金生水，水生木，木生火，火生土，土生金，这就是生成的规律，循环往复无穷无尽。肺生肾，肾生肝，肝生心，心生脾，脾生肺，上下相互荣养，没有休息停止的时候。所以《金匮要略·至真要大论》中说：心生成血，血是肌肉的母亲；脾生成肌肉，肌肉是血液的居所；肺主管气，气是骨骼的基础；肾对应骨骼，骨骼是筋腱的根本；肝联系筋腱，筋腱是血液的来源。五脏与五行相互成就、相互滋生，昼夜流转，没有开始也没有结束。顺应它则吉祥，违背它则凶险。天地的阴阳和五行的道理，蕴含在人体之中。人若能掌握它，就可以超出阴阳数量的限制，夺取天地的机枢，领悟五行的精要，达到无始无终、神仙不死境界。
暴风带来酷热，云物飞扬，早晨昏暗傍晚晴朗，夜晚炎热白天寒冷。该冷的时候不冷，该下雨的时候不下雨，水源枯竭土壤崩坏，时节岁数大旱，草木枯萎憔悴，江河干涸断流。这是天地的阳厥（阳气郁闭不通）。突然壅塞阻滞，忽然气喘急促，四肢无法收持控制，大小肠等腑气不利，耳聋目盲，咽喉干燥口舌焦枯，舌头生疮，鼻子流出清涕，脸颊发红心烦意乱，头晕脑重，双眼像火一样，全身如同燃烧。平时不能做的突然能做，平时不想做的突然想做，登上高处唱歌大笑，扔掉衣服奔跑，胡言乱语，不认识亲人疏远之人。发作躁动没有节制，喝水不停，胸膈部膨胀，腹部和胁肋部满闷，背部生疽肉烂，烦躁溃散消中（多食易饥之症），食物不进胃，水液不穿肠，突然肿胀暴满，呼叫，昏沉冒昧，不省人事，疼痛不知道部位所在。这是人的阳厥。阳厥的脉象，举按有力的预后良好可生，脉绝的预后不良致死。
Yin and Yang are the pivot and mechanism of Heaven and Earth. The Five Elements (Metal, Wood, Water, Fire, Earth) are the beginning and end of Yin and Yang. Without Yin and Yang, Heaven and Earth cannot be formed; without the Five Elements, Yin and Yang cannot function. Therefore, humans are formed by Heaven and Earth but perish due to imbalances in Yin and Yang, arising from the reversal or compliance of the Five Elements.
Heaven and Earth possess Yin and Yang and the Five Elements; humans possess blood vessels and the Zang organs (Solid Organs). The Five Elements refer to Metal, Wood, Water, Fire, and Earth. The Zang organs refer to the Lung, Liver, Heart, Kidney, and Spleen. Metal generates Water, Water generates Wood, Wood generates Fire, Fire generates Earth, and Earth generates Metal. This is the way of generation, cycling endlessly. The Lung generates the Kidney, the Kidney generates the Liver, the Liver generates the Heart, the Heart generates the Spleen, and the Spleen generates the Lung. They nourish each other above and below without rest. Thus, it is stated in *Jinkui Yaolue: Zhizhen Yao Da Lun*: "The Heart generates Blood; Blood is the mother of flesh." "The Spleen generates flesh; flesh is the residence of Blood." "The Lung governs Qi; Qi is the foundation of bones." "The Kidney corresponds to bones; bones are the root of sinews." "The Liver connects with sinews; sinews are the source of Blood." The Zang organs and the Five Elements mutually support and generate each other, flowing day and night without beginning or end. Compliance brings auspiciousness; violation brings disaster. The principles of Yin-Yang and the Five Elements of Heaven and Earth are contained within humans. One who grasps them can transcend the numbers of Yin and Yang, seize the mechanism of Heaven and Earth, and appreciate the essence of the Five Elements, achieving a state without beginning or end, becoming an immortal who does not die.
Violent storms bring intense heat; clouds and objects fly about. Mornings are dark while evenings are clear; nights are hot while days are cold. It should be cold but is not; it should rain but does not. Water sources dry up, soil crumbles, causing severe drought in the seasons. Grass and trees wither and decay, rivers and streams become depleted and dry. This is the Yang Jue (Yang Reversal/Obstruction) of Heaven and Earth. [In humans:] sudden obstruction and blockage, abrupt panting and shortness of breath, limbs unable to hold themselves, dysfunction of the Fu organs (Hollow Organs), deafness and blindness, dry throat and scorched mouth, sores on the tongue, clear discharge from the nose, red cheeks and vexation, dizziness and heavy head, eyes like fire, whole body feeling like burning. Those who could not do something before suddenly can; those they did not desire before suddenly desire. Climbing high places, singing and laughing, discarding clothes and running wildly, speaking nonsense and妄语 (delirious speech), failing to distinguish between relatives and strangers. Restlessness erupts without limit, drinking water ceaselessly, distension of the chest and diaphragm, fullness and oppression in the abdomen and hypochondrium, back carbuncles with rotting flesh, vexation, ulceration, Xiao Zhong (wasting-thirst syndrome with excessive hunger), food failing to enter the stomach, water failing to pass through the intestines, sudden swelling and bloating, shouting, coma and confusion, loss of consciousness, pain without knowing its location. This is the Yang Jue of humans. Regarding the pulse of Yang Jue: if the pulse is strong upon lifting and pressing, life is possible; if the pulse is absent/extinct, death ensues.
