黄帝在明堂，雷公请曰∶臣授业传之，行教以经论，从容形法，阴阳刺灸，汤药所滋。行治有贤不肖，
未必能十全。若先言悲哀喜怒，燥湿寒暑，阴阳妇女，请问其所以然者，卑贱富贵，人之形体所从，群下通使，
临事以适道术，谨闻命矣。请问有HT 愚仆漏之问，不在经者，欲闻其状。帝曰∶大矣。公请问∶哭泣而泪不
出者，若出而少涕，其故何也？帝曰∶在经有也。复问∶不知水所从生，涕所从出也。帝曰∶若问此者，
无益于治也，工之所知，道之所生也。夫心者，五脏之专精也，目者其窍也，华色者其荣也，是以人有德也，
则气和于目，有亡，忧知于色。是以悲哀则泣下，泣下水所
由生。水宗者积水也，积水者至阴也，至阴者肾之精也。宗精之水所以不出者，是精持之也，辅之裹之，故水
不行也。夫水之精为志，火之精为神，水火相感，神志俱悲，是以目之水生也。故谚言曰∶心悲名曰志悲。
志与心精，共凑于目也。是以俱悲则神气传于心精，上不传于志而志独悲，故泣出也。泣涕者脑也，脑者阴也，
髓者骨之充也，故脑渗为涕。志者骨之主也，是以水流而涕从之者，其行类也。夫涕之与泣者，譬如人之
兄弟，急则俱死，生则俱生，其志以早悲，是以涕泣俱出而横行也。夫人涕泣俱出而相从者，所属之类也。
雷公曰∶大矣。请问人哭泣而泪不出者，若出而少，涕不从之何也？帝曰∶
夫泣不出者，哭不悲也。不泣者，神不慈也。神不慈则志不悲，阴阳相持，泣安能独来。夫志悲者惋，惋则冲
阴，冲阴则志去目，志去则神不守精，精神去目，涕泣出也。且子独不诵不念夫经言乎，厥则目无所见。夫
人厥则阳气并于上，阴气并于下。阳并于上，则火独光也；阴并于下，则足寒，足寒则胀也。夫一水不胜五火，
故目 盲。是以冲风，泣下而不止。夫风之中目也，阳气内守于精，是火气燔目，故见风则泣下也。有以比之，
夫火疾风生乃能雨，此之类也。

黄帝在明堂，雷公请教说：“我传授学业、传承医道，按照经典论述进行教学，从容地研究形体与法度，阴阳刺灸以及汤药的滋养。治疗中有贤能和不肖之分，未必都能十全十美。如果先陈述悲哀喜怒、燥湿寒暑、阴阳妇女等方面的情况，请问它们产生的原因，涉及卑贱富贵、人的形体来源、下属通使等情况，临事时顺应道术，我已恭敬地听命了。现在我想提出一些愚拙仆漏的问题，这些不在经典记载中的内容，想要听听它的状况。”黄帝说：“这个问题很大。”雷公接着问：“哭泣时眼泪不出，或者眼泪流出但鼻涕很少，这是什么缘故？”黄帝说：“这在经典中是有记载的。”雷公又问：“不知道水是从哪里产生的，鼻涕是从哪里出来的。”黄帝说：“如果问这些问题，对治疗没有益处，这是工匠所知道的，是道的产生之处。心，是五脏的精气汇聚之处，眼睛是心的外窍，面色光泽是心的荣华表现，所以人有德行，那么和气就调和于眼睛；如果有缺失，忧愁就会表现在面色上。所以悲哀就会流泪，泪水就是由此产生的。水的宗源是积水，积水属于至阴，至阴就是肾的精气。宗精之水之所以不流出，是因为精气持守它，辅助并包裹它，所以水不流动。水的精华在于志，火的精华在于神，水火相互感应，神和志都感到悲哀，所以眼睛产生泪水。所以谚语说：‘心悲叫做志悲。’志和心精，共同凑集于眼睛。所以都感到悲哀时，神气传于心精，如果不传于志而只有志单独悲哀，所以泪水流出。涕和泪都属于脑，脑属于阴，髓是骨骼的填充物，所以脑渗漏成为涕。志是骨的主宰，所以水流而涕随之，它们的运行规律类似。涕和泪，就像人的兄弟，紧急时一起死亡，生存时一起生存，因为志先悲哀，所以涕和泪一起流出且横向流淌。人涕和泪一起流出且相互跟随，是因为它们所属的类别相同。”
雷公说：“说得真好。请问人哭泣时眼泪不出，或者流出但很少，鼻涕不随之而来，这是什么原因？”黄帝说：“眼泪出不出来，取决于哭得是否悲哀。不流泪，是因为神不慈爱。神不慈爱则志不悲哀，阴阳相互持守，眼泪怎么能独自出来。志悲哀时会感到郁闷，郁闷则会冲击阴气，冲击阴气则志离开眼睛，志离开则神不能守住精气，精神离开眼睛，涕和泪就流出了。况且你难道没有诵读和思考经言吗？厥证会导致眼睛看不见。人发生厥证时，阳气并聚于上部，阴气并聚于下部。阳并于上，则火独自发光；阴并于下，则脚冷，脚冷则腹胀。一水不能胜过五火，所以眼睛失明。因此遇到冲风，泪水不止。风邪侵入眼睛，阳气内守于精气，这是火气焚烧眼睛，所以见到风就流泪。这可以用其他事物类比，大火猛烈风生才能下雨，这就是类似的道理。”

Huangdi was in the Mingtang (Bright Hall), and Leigong asked respectfully: "I have received instruction and transmitted it, teaching according to the classic treatises, calmly studying forms and methods, Yin-Yang acupuncture and moxibustion, and the nourishing effects of herbal decoctions. In treatment, there are distinctions between the virtuous/capable and the incompetent, and perfection is not always achieved. If one first discusses sorrow, anger, joy, dryness, dampness, cold, heat, Yin-Yang, and women's diseases, asking for their causes, involving status of lowly or noble, the origin of human physique, and the communication of subordinates, adapting to the Daoist arts in practice, I have listened with reverence. Now I wish to ask some foolish and trivial questions that are not recorded in the classics, and I desire to hear their descriptions." Huangdi said: "This is significant." Leigong then asked: "When crying, tears do not flow out, or if they flow out, there is little mucus; what is the reason?" Huangdi said: "This is recorded in the classics." Leigong asked again: "I do not know where water originates, nor where mucus comes from." Huangdi said: "Asking such questions is of no benefit to treatment; this is knowledge known to craftsmen, from which the Dao arises. The Heart is the essence of the Five Zang organs, the eyes are its orifices, and the luster of the complexion is its glory. Therefore, when a person possesses virtue, harmonious Qi flows into the eyes; if there is deficiency, sorrow manifests in the complexion. Thus, sorrow leads to weeping, and tears originate from this. The source of water is accumulated water; accumulated water belongs to Extreme Yin; Extreme Yin is the Essence of the Kidney. The water of the Zong Essence does not flow out because it is held by the Essence, assisted and wrapped by it, so the water does not move. The essence of Water lies in Zhi (Will/Intent), and the essence of Fire lies in Shen (Spirit). When Water and Fire interact, and both Shen and Zhi feel sorrow, water is produced in the eyes. Hence the proverb says: 'Heart sorrow is called Zhi sorrow.' Zhi and Heart Essence gather together at the eyes. Therefore, when both feel sorrow, Shen Qi transmits to the Heart Essence; if it does not transmit to Zhi and only Zhi feels sorrow alone, then tears flow. Mucus and tears belong to the Brain; the Brain is Yin; Marrow fills the bones; thus, brain leakage becomes mucus. Zhi is the master of the bones; therefore, as water flows, mucus follows them, as their movement patterns are similar. Mucus and tears are like brothers; in urgency, they die together; in life, they live together. Because Zhi grieves early, mucus and tears flow out together and spread horizontally. When mucus and tears flow out together and follow each other, it is because they belong to the same category."
Leigong said: "Very profound. I ask: when a person cries but tears do not flow out, or flow out sparingly, and mucus does not follow, what is the reason?" Huangdi said: "Whether tears flow depends on whether the crying is heartfelt. If tears do not flow, it is because Shen is not compassionate. If Shen is not compassionate, Zhi is not sorrowful. Yin and Yang hold each other in balance; how can tears come alone? When Zhi is sorrowful, it feels suppressed; suppression impacts Yin; impacting Yin causes Zhi to leave the eyes; when Zhi leaves, Shen cannot guard the Essence; when Spirit and Essence leave the eyes, mucus and tears flow. Moreover, have you not read and reflected upon the classic statements? Jue syndrome causes blindness in the eyes. When a person suffers from Jue syndrome, Yang Qi gathers in the upper part, and Yin Qi gathers in the lower part. Yang gathering above means Fire shines alone; Yin gathering below means cold feet; cold feet lead to abdominal distension. One Water cannot overcome Five Fires, hence the eyes become blind. Therefore, when encountering wind, tears flow incessantly. When Wind pathogen invades the eyes, Yang Qi is internally guarded within the Essence; this is Fire Qi burning the eyes, hence tears flow upon seeing wind. This can be compared to other phenomena: intense fire and strong wind generate rain; this is of the same category."
