阴阳者，天地之枢机；五行者，阴阳之终始；非阴阳不能为天地，非五行不能为阴阳。
故人者成于天地，败于阴阳，由五行从逆而生焉。天地有阴阳五行，人有血脉五脏；五行者，
金
循环不穷；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，筋为血之原。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，中合于人，人得之可以出阴阳之数，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，唇舌生疮，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，烦愦溃中，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，是阴阳变化的开始与终结；没有阴阳就不能形成天地，没有五行就不能体现阴阳。
所以人是由天地所成就，又因阴阳失调而败坏，这是由于五行顺行或逆乱而产生的结果。天与地有阴阳和五行，人有血脉和五脏；五行之间循环往复，无穷无尽；肺金生肾水，肾水生肝木，肝木生心火，心火生脾土，脾土再生肺金，上下相互滋养，从未停歇。因此《金匮要略·至真要大论》中说：“心主血，血是肌肉的根本；脾主肉，肉是血液的居所；肺主气，气是骨骼的基础；肾应骨，骨是筋脉的本源；肝主筋，筋是血液的源头。五脏对应五行，相互生成、相生相成，昼夜流转，没有终点也没有起点；顺应它则吉祥，违背它则凶险。天地的阴阳规律，五行的法则，与人相契合，人若能掌握这些道理，就可以超越阴阳的局限，夺取天地的玄机，领悟五行的精要，达到无始无终、如神仙般不死的状态。”
狂风骤起，热气逼人，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，年份大旱，草木枯萎憔悴，江河干涸断流，这是天地的“阳厥”（阳气亢盛至极导致的闭阻）；突然壅塞不通，忽然气喘急促，四肢无法收持控制，大小肠等腑气不通，耳聋目盲，咽喉干燥口舌焦裂，嘴唇舌头生疮，鼻子流出清涕，脸颊发红心烦意乱，头晕脑胀沉重，双眼似火，全身像火烧一样，平时做不到的事突然能做，平时不想做的事突然想做，登上高处唱歌大笑，扔掉衣服奔跑，胡言乱语，分不清亲疏关系，烦躁不安没有节制，不停地喝水，胸膈部膨胀，腹部和胁肋部满闷不适，背部疽疮肌肉腐烂，烦闷昏乱内部溃烂，食物进不了胃，水流不过肠道，突然肿胀暴满，叫喊呼救昏迷晕倒，不省人事，疼痛不知痛处所在，这是人的“阳厥”。阳厥病的脉象，如果轻取重按都有力的话预后良好可生，如果脉绝则死亡。
Yin and Yang are the pivot of heaven and earth; the Five Phases (Wu Xing) are the beginning and end of Yin and Yang. Without Yin and Yang, heaven and earth cannot be formed; without the Five Phases, Yin and Yang cannot manifest.
Therefore, humans are constituted by heaven and earth, yet they deteriorate due to imbalances in Yin and Yang, arising from the compliance or deviation of the Five Phases. Heaven and earth possess Yin and Yang and the Five Phases; humans possess blood vessels and the Zang organs. The Five Phases circulate endlessly; Metal generates Water, Water generates Wood, Wood generates Fire, Fire generates Earth, and Earth generates Metal again. They nourish each other above and below without rest. Thus, the *Jinkui Yaolue · Zhizhen Yao Da Lun* states: "The Heart governs Blood, which is the mother of flesh; the Spleen governs flesh, which is the residence of Blood; the Lung governs Qi, which is the foundation of bones; the Kidney corresponds to bones, which are the root of sinews; the Liver governs sinews, which are the origin of Blood. The five Zang organs correspond to the Five Phases, mutually generating and producing each other, flowing day and night without beginning or end. Following them brings auspiciousness; opposing them brings disaster. The principles of Yin and Yang and the Five Phases in heaven and earth align with humans. If humans can master these, they can transcend the numbers of Yin and Yang, seize the mechanism of heaven and earth, appreciate the essence of the Five Phases, and achieve a state without beginning or end, becoming immortal like immortals."
Sudden storms and intense heat, flying clouds and debris, morning darkness and evening clarity, nighttime heat and daytime cold, cold when it should not be cold, rain when it should not rain, dried-up water sources and crumbling soil, severe drought in the year, withered and decaying vegetation, and dried-up rivers and streams—this is the "Yang Jue" (Yang Collapse/Obstruction) of heaven and earth. Sudden blockage, sudden panting and shortness of breath, limbs unable to hold themselves, dysfunction of the Fu organs, deafness and blindness, dry throat and scorched mouth, sores on lips and tongue, clear nasal discharge, red cheeks and vexation, dizziness and heavy head, eyes like fire, body feeling like burning, performing actions previously impossible, desiring things previously unwanted, climbing high places singing and laughing, discarding clothes and running wildly, speaking madly and falsely, failing to distinguish between relatives and strangers, extreme restlessness without measure, drinking water incessantly, distension in the chest and diaphragm, fullness and oppression in the abdomen and hypochondrium, back carbuncles with rotting flesh, vexation and confusion with internal ulceration, food unable to enter the stomach, water unable to pass through the intestines, sudden swelling and bloating, shouting and fainting, loss of consciousness, pain with unknown location—this is the "Yang Jue" of humans. In Yang Jue, if the pulse is strong upon both superficial pressing and deep pressing, life is possible; if the pulse is absent, death ensues.
