素问曰∶两神相搏，合而成形，常先身生，是谓精。上焦开发，宣五谷味，薰肤充身，若雾露之溉，是谓气。腠理
发泄，汗出溱溱，是谓津。谷入气满，淖泽注于骨，骨属屈伸，泄泽，补益脑髓，皮肤润泽，是谓液。中焦受气取汁，
变化而赤，是谓血。壅遏营气，令无所避，是谓脉。精脱者，耳聋；气脱者，目不明，津脱者，腠理开，汗大泄，液
脱者，骨属屈伸不利，色夭，脑髓消，胫消，耳数鸣；血脱者，色白，夭然不泽，其脉空虚。
怵惕思虑则伤神，神伤则恐惧，流淫而不止。悲哀动中者，竭绝而失生。喜乐者，神惮散而不藏。愁忧者，气闭塞
而不行。盛怒者，迷惑而不治。恐惧者，神荡惮而本收。
心怵惕思虑则伤神，神伤则恐惧自失，破 脱肉，毛悴色夭，死于冬。
脾优而不解则伤意，意伤则 乱，四肢不举，毛悴色夭，死于春。
肝悲哀动中则伤魂，魂伤则狂忘不精，不精则不正，当令人筋缩而挛筋，两胁骨不举，毛悴色夭，死于秋。
肺喜乐无极则伤魄，魄伤则狂，狂者意不存人，皮革焦，毛悴色夭，死于夏。
肾盛怒而不止则伤志，志伤则喜忘，腰脊不可以俯仰屈伸，毛悴色夭，死于季夏。
恐惧而不解，则伤精，精伤则骨酸痿厥，精时自下。是故五脏主藏精者也，不可伤，伤则失守而阴虚，阴虚则无气，
无气则死矣。
《素问》说：男女两精结合，融合而成胎儿，这种物质通常在身体形成之前就已经存在，这就叫做“精”。上焦具有开发宣发的功能，布散五谷的精微气味，温煦肌肤，充实形体，就像雾露滋润万物一样，这就叫做“气”。腠理开泄，汗出连绵不断，这就叫做“津”。饮食入胃后，谷气充盈，浓稠的汁液注入骨骼，使骨节能够屈伸自如；其稀薄的部分渗入体内，补益脑髓，使皮肤润泽，这就叫做“液”。中焦接受水谷之气，提取其中的汁液，经过变化变成红色，这就叫做“血”。脉道约束营气，使其运行有度而不妄行，这就叫做“脉”。
精气衰竭的人，会耳聋；元气衰竭的人，视力不明；津液衰竭的人，腠理疏松，大汗淋漓；体液衰竭的人，关节屈伸不利，面色枯槁，脑髓减少，小腿消瘦，耳朵经常鸣响；血液衰竭的人，面色苍白，干枯无光泽，脉搏空虚无力。
惊恐思虑过度会损伤心神，心神受损就会恐惧不安，导致精气滑脱不止。悲哀情绪扰动内心，会导致生机竭绝而丧失生命。过度喜乐会使心神涣散而不能内守。忧愁会导致气机闭塞而不能正常运行。大怒会让人神志迷惑而失去理智。恐惧会让心神动荡惊骇而收敛失守。
心经受惊恐思虑的困扰会损伤心神，心神受损就会恐惧且自我控制能力丧失，肌肉破溃消瘦，毛发憔悴，面色枯槁，这类病症在冬季容易致死。
脾经忧思不解会损伤脾意，脾意受损就会思维混乱，四肢不能抬举，毛发憔悴，面色枯槁，这类病症在春季容易致死。
肝经受悲哀情绪的扰动会损伤肝魂，肝魂受损就会狂妄健忘、精神不集中，精神不集中就会导致行为不正，进而使人筋脉收缩挛急，两胁肋骨难以抬起，毛发憔悴，面色枯槁，这类病症在秋季容易致死。
肺经受喜乐无极的困扰会损伤肺魄，肺魄受损就会发狂，狂者心中没有他人，皮肤皮革焦枯，毛发憔悴，面色枯槁，这类病症在夏季容易致死。
肾经受盛怒不止的影响会损伤肾志，肾志受损就会喜欢遗忘，腰脊不能俯仰屈伸，毛发憔悴，面色枯槁，这类病症在长夏（季夏）容易致死。
如果恐惧情绪长期不解，就会损伤肾精，肾精受损就会出现骨骼酸痛、痿软厥冷，以及精液自行滑脱的症状。因此，五脏是贮藏精气的器官，不可受到损伤，一旦损伤就会使精气失守而导致阴虚，阴虚则无法化生阳气，没有阳气人就会死亡。
The *Suwen* (Basic Questions) states: When the two spirits (male and female essences) interact, they combine to form a shape. This substance is often generated prior to the body itself; this is referred to as **Jing** (Essence). The Upper Jiao (Upper Burner) develops and disseminates, distributing the flavors of the five grains, warming the skin, and filling the body, much like mist and dew nourishing all things; this is referred to as **Qi** (Vital Energy). When the interstices (Couli) open and sweat pours forth profusely, this is referred to as **Jin** (Thin Fluids). When food enters and Qi fills the interior, the thick and moist fluids are injected into the bones, allowing the skeletal joints to flex and extend; the thinner parts permeate inward to replenish the brain marrow and keep the skin moist and lustrous; this is referred to as **Ye** (Thick Fluids). The Middle Jiao receives Qi and extracts the juice, which transforms and turns red; this is referred to as **Xue** (Blood). The vessels constrain the Ying Qi (Nutritive Energy), preventing it from escaping; this is referred to as **Mai** (Vessels/Pulse).
When Jing is depleted, there is deafness; when Qi is depleted, vision is unclear; when Jin is depleted, the Couli open and sweat flows profusely; when Ye is depleted, the skeletal joints are stiff and difficult to flex or extend, the complexion is dull, the brain marrow diminishes, the shins atrophy, and the ears ring frequently; when Xue is depleted, the complexion is white, dry and lacking luster, and the pulse is empty and forceless.
Fright and excessive worry injure the Shen (Spirit); when the Shen is injured, fear arises, leading to the uncontrolled leakage of essence. Sorrow that disturbs the interior exhausts life force and leads to loss of vitality. Excessive joy causes the Shen to scatter and fail to remain stored. Worry and grief cause Qi to become blocked and fail to circulate. Extreme anger causes confusion and loss of rational control. Fear causes the Shen to be agitated and its root to retract improperly.
If the Heart is troubled by fright and worry, the Shen is injured; when the Shen is injured, there is fear and loss of self-control, muscles waste away, hair becomes brittle, the complexion is dull, and death may occur in Winter.
If the Spleen is troubled by unresolved worry, the Yi (Intellect/Intent) is injured; when the Yi is injured, thoughts become chaotic, the four limbs cannot be lifted, hair becomes brittle, the complexion is dull, and death may occur in Spring.
If the Liver is disturbed by sorrow, the Hun (Ethereal Soul) is injured; when the Hun is injured, there is madness, forgetfulness, and lack of focus; lack of focus leads to moral deviation, causing tendon contraction and spasms, inability to raise the costal region, brittle hair, dull complexion, and death may occur in Autumn.
If the Lungs are affected by boundless joy, the Po (Corporeal Soul) is injured; when the Po is injured, there is madness, where the mad person disregards others, the skin and leather become scorched/dry, hair becomes brittle, the complexion is dull, and death may occur in Summer.
If the Kidneys are subjected to unceasing rage, the Zhi (Willpower) is injured; when the Zhi is injured, there is frequent forgetfulness, inability to bend or extend the waist and spine, brittle hair, dull complexion, and death may occur in Late Summer (Ji Xia).
If fear remains unresolved, it injures Jing; when Jing is injured, there is soreness and coldness of the bones, flaccidity, and spontaneous emission of essence. Therefore, the Five Zang Organs store Jing; they must not be injured. If injured, Jing fails to be maintained, leading to Yin Deficiency. Yin Deficiency results in a lack of Qi, and without Qi, death ensues.
