病有灾怪。何谓也病者应寒而反热。应热而反寒。应吐而不吐。应泻而不泻。应汗而不汗。应语而不语。应
寐而不寐。应水而不水。皆属灾怪也。此乃五脏之气不相随从而致之矣。四逆者不治。四逆者谓主客运
气俱不得时也。
病起于六腑者阳之系也。阳之发也。或上或下。或内或外。或蓄在中行之极也。有能歌笑者。有能悲泣者。
有能奔走者。有能呻吟者。有自委曲者。有自高贤者。有寤而不寐者。有能食而不便利者。
有不能食而便自利者。有能言而声清者。有不能言而声昧者。状各不同皆生六腑也。喜其通者因以通
之。喜其塞者因以塞之。喜其水者以水济之。喜其冰者以冰助之。病者之乐慎勿违背。亦不可强抑之也。
如此从顺。则十生其十。百生其百。疾无不愈矣。
病起于五脏者。皆阴之属也。其发也。或偏枯。或痿 。或外寒而内热。或外热而内寒。或心腹膨胀。或手足
拳挛。或口眼不正。或皮肤不仁。或行步艰难。或身体强硬。或吐泻不息。或疼痛不宁。或暴无语。或久无音。
绵绵默默。状若死人。如斯之候。备出于阴。阴之盛也。阳必不足。阳之盛也。阴必不盈。故前论云阳不足则
助之以火精。阴不足则济之以水母者是也。故喜其汗者汗之。喜其温者温之。喜其热者热之。喜其火者
火之。喜其汤者汤之。温热汤火。亦在其宜。慎勿强之。如是则万全其万。水火之法真阴阳也。治救之道。当
详明矣。
疾病中有一种情况称为“灾怪”。什么是灾怪呢？是指病人本应感到寒冷却反而发热，本应发热却反而畏寒；本应呕吐却不呕吐，本应腹泻却不腹泻；本应出汗却不出汗，本应胡言乱语却沉默不语；本应入睡却无法入睡，本应饮水却不饮水。这些现象都属于“灾怪”。这是由于五脏之气不能相互协调顺承所导致的。如果出现四肢厥逆（四逆），则属于难治之症。所谓“四逆”，是指主气与客气均不得其时，阴阳失调严重。
疾病起源于六腑的，属于阳的系统。阳气发动时，病位或在上、或在下、或在内、或在外的极深处。有的患者表现为能歌笑，有的表现为悲泣，有的表现为奔走狂奔，有的表现为呻吟痛苦，有的表现为身体委曲蜷缩，有的表现为自视甚高、自以为贤能，有的表现为清醒却无法入睡，有的表现为能吃但大小便不通利，有的表现为不能吃但大便自利（滑泄）。有的患者能说话且声音清亮，有的患者不能说话且声音晦暗。症状表现各不相同，但都源于六腑的功能异常。治疗时应顺应患者的喜好：喜欢通畅的就用通法治疗，喜欢闭塞的就用塞法治疗，喜欢水的就用水液来济助，喜欢冷的就用冰寒之物来辅助。对于病人的喜好，切勿违背，也不可强行压制。如此顺应病情，则十例可愈十例，百例可愈百例，疾病没有不能治愈的。
疾病起源于五脏的，都属于阴的范畴。其发病时，或表现为半身不遂（偏枯），或表现为肢体痿软无力（痿证），或表现为外感寒邪而内部发热，或表现为外部发热而内部寒冷，或表现为心腹胀满，或表现为手足拳曲挛急，或表现为口眼歪斜，或表现为皮肤麻木不仁，或表现为行走困难，或表现为身体僵硬强直，或表现为呕吐腹泻不止，或表现为疼痛不安，或表现为突然失语，或表现为长期失音，默默无声，状如死人。像这样的候象，完全出于阴盛。阴气旺盛时，阳气必然不足；阳气旺盛时，阴气必然亏虚。所以前文论述说：阳气不足就用火精（温热药物/疗法）来资助，阴气不足就用水母（寒凉药物/疗法）来济助，就是这个道理。因此，喜欢发汗的就用汗法，喜欢温热的就用温法，喜欢热性的就用热法，喜欢火疗的就用火疗，喜欢汤药的就用汤药。温热、汤剂、火法的使用，也在于适宜得当。切勿强行干预。这样就能万无一失。水法和火法，正是真正的阴阳之道。救治疾病的原理，应当详细明了。
There is a condition known as "Zaiguai" (Disaster and Anomaly). What is meant by this? It refers to situations where a patient, who should feel cold, instead presents with heat; or who should present with heat, instead feels cold. The patient may need to vomit but does not, or needs to have diarrhea but does not. They may need to sweat but do not, or should be delirious but remain silent. They may need to sleep but cannot, or should drink water but refuse. All these phenomena belong to "Zaiguai". This is caused by the five Zang organs' Qi failing to follow and coordinate with one another. If "Sini" (Four Reversals/Cold Extremities) occurs, it is considered incurable. "Sini" refers to a state where both the ruling Qi (Zhuyun) and the seasonal Qi (Kyun) are out of season, indicating severe disharmony.
Diseases originating in the Six Fu organs belong to the Yang system. When Yang pathogenic factors arise, they may manifest above or below, inside or outside, or accumulate at the extreme depths of the middle burner. Some patients may exhibit singing and laughing, others weeping and crying, others running wildly, others groaning in pain, others curling up in submission, others acting arrogantly as if superior or virtuous, others remaining awake unable to sleep, others able to eat but suffering from constipation, and others unable to eat but experiencing spontaneous diarrhea. Some can speak with clear voices, while others cannot speak and have muffled voices. Although the manifestations vary, they all stem from dysfunction of the Six Fu organs. Treatment should accord with the patient's inclination: if they favor unblocking, use unblocking methods; if they favor obstruction, use obstructing methods; if they desire water, assist with fluids; if they desire cold, assist with ice/cold agents. Do not violate the patient's preferences, nor forcibly suppress them. By following this compliance, ten cases will yield ten cures, and hundred cases will yield hundred cures; no disease will remain uncured.
Diseases originating in the Five Zang organs all belong to Yin. Their onset may present as hemiplegia (Piangu), flaccidity syndrome (Wei), exterior cold with interior heat, or exterior heat with interior cold. Other symptoms include abdominal distension, clenched and contracted hands and feet, deviation of the mouth and eyes, numbness of the skin, difficulty walking, stiffness and rigidity of the body, incessant vomiting and diarrhea, unrelenting pain, sudden aphasia, or long-term loss of voice. The patient may lie silent and motionless, resembling a corpse. Such presentations are entirely due to Yin excess. When Yin is excessive, Yang must be deficient; when Yang is excessive, Yin must be insufficient. As stated in previous discussions: if Yang is deficient, aid it with Fire Essence (warm/hot therapies); if Yin is deficient, supplement it with Water Mother (cool/cold therapies). Therefore, if the patient favors sweating, induce sweating; if they favor warmth, apply warming methods; if they favor heat, apply hot methods; if they favor fire therapy, use fire; if they favor decoctions, administer herbal soups. The application of warm, hot, decoction, and fire therapies must be appropriate. Do not force treatment against the natural inclination. In this way, ten thousand cases will be completely resolved. The methods of Water and Fire represent true Yin and Yang. The principles of healing and rescue should be thoroughly understood.
