在天的热（指温暖炽盛、暑热的作用），在地化为火，在人体对应心脏。（注：原文此处有缺漏或错简，根据中医理论及下文逻辑，应指心主热/火）。
燥气容易损伤肺脏，寒气容易损伤肾脏，而暑气容易损伤心包络（心包络又称膻中，位于胸膈之间，主管暑气，所以暑气潜伏于三焦、膈胃的胜复之气中）。
形体受寒、饮食生冷是肺的害处；饥饱不均、劳累倦怠是脾的伤处。外在的六淫邪气相互乘袭，内在的七情互相感应。凡是上述几种情况，都是脏腑的邪气。根据其主治关系去寻找是哪一脏腑受到了侵害，就能知道了。
心主管血液，所藏的是神志，上应于声音为笑，颜色为赤，气味为焦，味道为苦，津液为汗。
肝主管筋脉，所藏的是魂，上应于眼睛，外发为呼喊声，颜色为青，气味为臊，味道为酸，津液为泪。
肾主管骨骼，所藏的是精与志，上应于耳朵，外发为呻吟声，颜色为黑，气味为腐，味道为咸，津液为唾（肾冷则多唾，肾热则多渴）。
肺主管气，所藏的是魄，外应于皮毛，声音为哭，颜色为白，气味为腥，味道为辛，津液为涕。
脾主管肌肉，所藏的是意（注：原文“竟”疑为“意”之误，脾藏意），外应于四肢，声音为歌，颜色为黄，气味为香，味道为甘，津液为涎。
所以心和肺在上部，主管血脉，贮藏精血。脾居于中州，又是精血、脉气的滋养来源。
心的正常脉象，浮大而散。肾的正常脉象，沉濡而滑。肺的正常脉象，短涩而浮。脾的正常脉象，和缓而大。所谓的“平脉”，春脉弦，夏脉钩（王叔和说夏脉洪大，取火脉来势盛大之意），秋脉毛，冬脉石。这是因为四季当旺之气不同。
四时各旺七十二日，土气为季脉，每季最后一个月寄旺十八日。春季脉象弦中带缓，夏季脉象钩中带缓，秋季脉象毛中带缓，冬季脉象石中带缓。合起来看四季，也是七十二日。
所谓春弦，是指端直的样子，细软而长，轻虚似浮。夏钩，是指洪大的样子，浮大而散，来势急而去势慢。秋毛，是指稀软的样子，轻虚似浮。冬石，是指坚硬的样子，按之如弹石，去势急促。
土的脉象温和浓重，气行于脏腑之中，平和之象不可得见，只有衰退时才会显现出来，大概是顺应时节略微可见罢了。其中必须含有谷气和胃气的调和。如果脉象像张开的弓弦那样硬，像拿着绳索那样紧，像夺索那样劲急，像弹石那样坚硬，这些都是危重的脉象。这是完全没有胃气的表现，能长久吗？
如果是春天见到钩脉（心火脉），夏天见到毛脉（肺金脉），秋天见到石脉（肾水脉），冬天见到弦脉（肝木脉），或者四季见到火脉、土脉、木脉等相克之脉，比如心脉克肺脉，肺脉克肝脉，肝脉克肾脉，肾脉克心脉，这都属于邪脉。一个脏腑没有正气，还能做人吗？
至于各个腑的脉象，小肠脉洪大，大肠脉微涩，膀胱脉微沉，胃脉微缓，胆脉微弦急。这没有别的原因，是因为腑的脉象与其相表里的脏的脉象近似罢了。
再说古人所说的九脏，又是怎么回事呢？回答说：形脏有四，一是头角，二是耳目口齿，三是手，四是足；神藏有五，在心藏神，在肝藏魂，在肺藏魄，在脾藏意，在肾藏志。
面色是神志的旗帜，如果五脏的精气已散失其本色，必定会出现枯槁怪异的面色，应当会夭亡。
虽然脉候不同，但归结为寒证或虚证是一样的。脉数、实、长、洪，虽然形态不像，但归结为热证是一样的。
病出于肝，诸脉皆弦（注：原文“缓”疑为“弦”之误，肝主弦），吾知其病出于肝。诸脉皆缓，吾知其病出于脾。诸脉皆涩，吾知其病出于肺。诸脉皆沉滑，病不在肾乎？
若结合脏腑位置来观察，假如脉搏跳动急促（数）在左寸部，说明热气入于心；浮取而得，则热气入于小肠。脉搏迟缓（迟）在左尺部，迟脉主寒，沉取而得，则寒气入于膀胱。其余的可以以此类推。
The wind in heaven transforms into wood on earth, and corresponds to the Liver in humans. The Liver exclusively governs wind.
The heat in heaven (referring to the function of warmth, blazing heat, and summer heat) transforms into fire on earth, and corresponds to the Heart in humans.
Dryness tends to injure the Lung, Cold tends to injure the Kidney, and Summer-heat tends to injure the Pericardium (the Pericardium, also known as Danzhong, is located between the chest and diaphragm and governs summer-heat; thus, summer-heat lies latent within the Sheng-Fu Qi of the Sanjiao, diaphragm, stomach, and intestines).
Exposure to cold and consumption of cold drinks are harms to the Lung; irregular eating and overexertion are injuries to the Spleen. External pathogenic factors (Six Evils) mutually attack, and internal emotional factors (Seven Emotions) mutually interact. All such conditions constitute pathogenic factors of the Zang organs. By tracing back to which Zang organ is affected based on its governing relationships, one can identify the cause.
The Heart governs Blood and houses the Shen (Spirit); it manifests externally as laughter, corresponds to the color red, the odor scorched, the taste bitter, and the fluid sweat.
The Liver governs the Tendons and houses the Hun (Ethereal Soul); it manifests externally through the eyes and shouting, corresponds to the color green, the odor musky, the taste sour, and the fluid tears.
The Kidney governs the Bones and houses the Jing (Essence) and Zhi (Will); it manifests externally through the ears and groaning, corresponds to the color black, the odor putrid, the taste salty, and the fluid saliva (Cold in the Kidney leads to excessive saliva; Heat in the Kidney leads to excessive thirst).
The Lung governs Qi and houses the Po (Corporeal Soul); it manifests externally on the skin and hair, corresponds to the sound weeping, the color white, the odor fishy, the taste pungent, and the fluid mucus.
The Spleen governs the Muscles and houses the Yi (Intellect); it manifests externally on the four limbs, corresponds to the sound singing, the color yellow, the odor fragrant, the taste sweet, and the fluid drool.
Therefore, the Heart and Lung are located superiorly, governing the Mai (Vessels) and storing Jing and Blood. The Spleen resides in the Central Region (Zhongzhou) and serves as the nourishment for Jing, Blood, Vessels, and Qi.
The normal pulse of the Heart is floating, large, and scattered. The normal pulse of the Kidney is deep, soft, and slippery. The normal pulse of the Lung is short, rough, and floating. The normal pulse of the Spleen is harmonious, moderate, and large.
The "Ping" (Normal) pulses correspond to the seasons: Spring is Xian (Wiry), Summer is Gou (Hooked/Hong) [Shuhe stated that the Summer pulse is Hong, taking the meaning of the Fire pulse coming with vigor], Autumn is Mao (Feather-like), and Winter is Shi (Stone-like). This is because each season has its flourishing Qi.
Each season flourishes for 72 days. Earth Qi is the seasonal pulse, flourishing for 18 days in the last month of each season. In Spring, the pulse is Xian with Huan (Moderate); in Summer, Gou with Huan; in Autumn, Mao with Huan; in Winter, Shi with Huan. Considering all four seasons together, this amounts to 72 days.
Xian (Wiry) refers to a straight and long shape, fine and soft, light and void, resembling floating. Gou (Hooked/Hong) refers to a large and abundant shape, floating and large, scattered, coming swiftly and departing slowly. Mao (Feather-like) refers to a sparse and soft shape, light and void, resembling floating. Shi (Stone-like) refers to a hard shape, pressing like throwing stones, departing swiftly.
The Earth pulse is warm and dense; Qi circulates within the Zang and Fu organs. Its peaceful state is not visible; it only appears when declining, manifesting slightly according to the season. It must contain the harmony of Gu Shen (Grain Spirit) and Wei Qi (Stomach Qi). If the pulse is like a drawn bowstring, or like grasping a rope, or like pulling a rope, or like throwing stones, these are all critical pulses indicating the complete absence of Wei Qi. How long can one survive?
If in Spring one sees the Gou pulse (Heart/Fire), in Summer the Mao pulse (Lung/Metal), in Autumn the Shi pulse (Kidney/Water), or in Winter the Xian pulse (Liver/Wood), or if in the Four Seasons one sees pulses that overcome each other—such as the Heart pulse overcoming the Lung, Lung overcoming Liver, Liver overcoming Kidney, and Kidney overcoming Heart—these are all pathological (Xie) pulses. Can a person exist if one Zang organ lacks Zheng Qi (Upright Qi)?
As for the pulses of the Fu organs: the Small Intestine pulse is Hong (Surging); the Large Intestine pulse is slightly Se (Rough); the Bladder pulse is slightly Chen (Deep); the Stomach pulse is slightly Huan (Moderate); and the Gallbladder pulse is slightly Xian Ji (Wiry and Urgent). There is no other reason for this; the pulses of the Fu organs approximate those of their paired Zang organs.
Furthermore, what did the ancients mean by the Nine Zang? They replied: There are four Form Zang (Xing Zang): 1. Head and horns (facial features), 2. Eyes, ears, mouth, and teeth, 3. Hands, 4. Feet. There are five Spirit Zang (Shen Zang): The Heart houses Shen; the Liver houses Hun; the Lung houses Po; the Spleen houses Yi; the Kidney houses Zhi.
Facial complexion is the banner of the Shen. If the colors of the Five Zang have dispersed from their true hues, one will inevitably see withered, strange appearances, indicating imminent death.
Although pulse indications vary, they ultimately reduce to either Cold or Deficiency. Pulses that are rapid (Shu), excess (Shi), long (Chang), or surging (Hong) may differ in form but all indicate Heat.
If the disease originates from the Liver, the pulses will all be Xian (Wiry); I know the disease originates from the Liver. If the pulses are all Huan (Moderate), I know the disease originates from the Spleen. If the pulses are all Se (Rough), I know the disease originates from the Lung. If the pulses are all Chen Hua (Deep and Slippery), is the disease not in the Kidney?
Observing in conjunction with Zang-Fu locations: For example, if the pulse is rapid (Shu) at the Left Cun position, heat has entered the Heart. If it is obtained by superficial palpation (Fu), heat has entered the Small Intestine. If the pulse is slow (Chi) at the Left Chi position, and Chi indicates Cold, if it is obtained by deep palpation (An), cold has entered the Bladder. The rest can be deduced in this manner.
