、怒、哀、惧、爱、恶、欲；一作好、爱、恶。情之所伤，则皆属火热。所谓阳动阴静
。故形神劳则躁不宁，静则清平也。是故上善若水，下愚如火。先圣曰∶六欲七情，为道之
患。属火故也。
如中风偏枯者，由心火暴甚，而水衰不能制之，则火能克金，金不能克木，
则肝木自甚，而兼于火热，则卒暴僵仆，多因五志七情过度，而卒病也。又如酒醉而热，则
五志七情竞起。故《经》曰∶战栗，惊惑，悲笑，谵妄歌唱，骂詈癫狂，皆为热也。故热甚癫狂
者，皆此证也。
（笑）
笑∶蕃茂、鲜淑、舒荣、彰显，火之化也。故喜为心火之志也。喜极而笑者，犹燔烁火
喜而鸣，笑之象也，故病笑者，火之甚也。或心本不喜，因侮戏而笑者，俗谓之冷笑。涉人
非道而伐之，使惭然失志，由是违己心则喜笑。
或以轻手扰人颈、腋、腹、胁、股、 、足
、趺，令人痒而笑者，由动乱扰挠，火之用也；静顺清谧，水之化也。皮肤彰显之分，属于
火也，嫩薄隐藏之分，属于水也。以火用扰其水分，使人惭然失志而痒，则水衰火旺，而为
笑也。
以手自扰而不笑者，不羞不痒故也。然羞惭而痒者，心火之化也。人失信志则羞渐者
，水衰火实故也。志与信者，肾水之化也。但痒而不羞，羞而不痒，皆不能为笑者，化微不
能变动故也。
（谵）
谵∶多言也，言为心声，犹火燔而鸣，故心火热则多言，犹醉而心热，故多言也。或寐
而多言者，俗云睡语，热之微也。若热甚则睡寤，而神昏不清，则谵语也。自汗、惊悸、咬
牙皆然。所谓寐则荣卫不能宣行于外，而气郁于内；是故里热发也。
夫上善若水，下愚如火
。故六欲七情，上善远之，而下愚迁之。其梦中喜、怒、哀、乐、好、恶、爱之七情，
非分而过，其不可胜者，寐则内热郁甚故也。凡人梦者，乃俗云梦中之梦，离道愈远；梦之觉者
，尚为道之梦也；故成道是为大觉，则六欲七情，莫能干也。古人言，梦者神迷也。病热而
能迁七情者，水衰道远故也。
（妄）
妄∶虚妄也，火为阳，故外清明而内浊昧。其主动乱，故心火热甚则肾水衰，而志不精
一。虚妄见闻，而自为问答，则神志失常，如见鬼神也。或以鬼神为阴，而见之则为阴极脱
阳，而无阳气者，妄意之言也。
（衄蔑血汗）
衄蔑血汗∶血出也。汗者浊也。心火热极则血有余，热气上甚，则为血溢，热势亢极，则燥
而汗浊，害承乃制，则色兼黑而为紫也。
Anger, sorrow, fear, love, dislike, and desire; alternatively stated as liking, love, and dislike. Injuries caused by emotional states all belong to Fire-Heat (Re). The principle is that Yang moves and Yin is still. Therefore, when the physical form and spirit are overworked, there is restlessness and lack of tranquility; when quiet, there is clarity and peace. Thus, the highest good is like water, while the lowest foolishness is like fire. The ancient sages said: The six desires and seven emotions are obstacles to the Dao because they belong to Fire.
For instance, in cases of wind-stroke with hemiplegia, it arises from a sudden excess of Heart Fire, while Kidney Water is deficient and unable to control it. Consequently, Fire conquers Metal, and Metal fails to control Wood, leading to an excessive state of Liver Wood combined with Fire-Heat. This results in sudden rigidity and collapse, often due to excessive stimulation of the five zhi and seven emotions, causing sudden illness. Similarly, intoxication with alcohol generates heat, causing the five zhi and seven emotions to arise competitively. Thus, the *Classic* states: trembling, confusion, grief mixed with laughter, delirious muttering or singing, cursing, mania, and madness are all manifestations of Heat. Therefore, mania and madness caused by severe Heat are all of this nature.
(Laughter)
Laughter: characterized by flourishing, freshness, comfort, and manifestation, it is the transformation of Fire. Hence, joy is the emotion associated with Heart Fire. Extreme joy leading to laughter is analogous to the sound produced by burning fire; thus, pathological laughter indicates an excess of Fire. Alternatively, if the heart does not originally feel joy but one laughs due to mockery or playfulness, it is commonly called a "cold smile." If one provokes another regarding their improper conduct, causing them to feel ashamed and lose their resolve, this violation of one's own heart leads to laughter.
If light touching disturbs the neck, axilla, abdomen, hypochondrium, thighs, popliteal fossa, feet, and dorsum of the feet, causing itching and laughter, this is due to agitation and disturbance, which is the function of Fire; tranquility and clarity are the transformation of Water. Areas of the skin that are prominent and manifest belong to Fire, while tender and hidden areas belong to Water. When the function of Fire disturbs the aspect of Water, causing shame and loss of resolve accompanied by itching, it indicates deficient Water and旺盛 Fire, resulting in laughter.
If self-tickling does not produce laughter, it is because there is no shame or itching. However, if there is shame and itching, it is the transformation of Heart Fire. When a person loses trust and resolve, feeling shame gradually, it is due to deficient Water and substantial Fire. Resolve and trust are transformations of Kidney Water. If there is itching without shame, or shame without itching, neither can produce laughter because the transformative power is too weak to cause change.
(Delirious Speech)
Delirious speech: excessive talking. Speech is the voice of the heart, analogous to the sound of burning fire. Therefore, when Heart Fire is hot, there is excessive talking, similar to being drunk with a hot heart. If one talks excessively during sleep, commonly known as somniloquy, it indicates mild Heat. If Heat is severe, waking occurs with mental confusion and lack of clarity, resulting in delirious speech. Spontaneous sweating, palpitations, and teeth-grinding are also related. It is said that during sleep, Ying and Wei Qi cannot circulate outward, leading to Qi stagnation internally; thus, interior Heat emerges.
The highest good is like water, the lowest foolishness is like fire. Therefore, those of high virtue keep the six desires and seven emotions at a distance, while the foolish indulge in them. The seven emotions—joy, anger, sorrow, happiness, liking, dislike, and love—that occur in dreams exceed proper limits. Those that cannot be overcome are due to severe internal Heat stagnation during sleep. Ordinary dreams are what common people call "dreams within dreams," moving further away from the Dao; those who awaken from dreams are still dreaming the dream of the Dao; thus, achieving the Dao is considered great awakening, where the six desires and seven emotions cannot interfere. The ancients said, dreaming is the bewilderment of the spirit. In febrile diseases where one indulges in the seven emotions, it is due to deficient Water and a distant path.
(Insanity/Falsehood)
Insanity: falsehood. Fire is Yang, so externally clear but internally turbid. It tends toward agitation. Therefore, when Heart Fire is excessive, Kidney Water becomes deficient, and the will lacks focus. False perceptions and hallucinations, engaging in self-dialogue, indicate abnormal spirit and will, such as seeing ghosts and spirits. Some regard ghosts and spirits as Yin; seeing them indicates extreme Yin expelling Yang, lacking Yang Qi, which constitutes delusional speech.
(Nasal Bleeding, Blood Sweating, etc.)
Nasal bleeding, blood in sweat: emission of blood. Sweat is turbid. When Heart Fire reaches extremity, blood becomes excessive. Severe rising Heat causes blood overflow. When Heat intensity is extreme, dryness and turbid sweat occur. Following the principle of mutual restriction, the color mixes with black to become purple.
