以辟方士之谬。而破轻信之惑。真救世之药石也。
人生有本性之乐，有权势之乐，有身体康健之乐。本性之乐，四季如春，万物一体。虽然居室简陋萧条，但快乐依然存在。虽然五官不全，但快乐依然存在。虽然身处夷狄之地或遭遇患难，快乐也依然存在。溪山风月，只要有我便是主人；草木石头禽鱼，亲近它们都是好朋友。何必沉溺于枕席之情，放纵淫佚呢？即使造物主也无法施展其捉弄手段了。至于权势之乐与长寿健康之乐，只有福分深厚的人才能兼而有之。大概获得尊贵与获得长寿，其源头似乎分为两条途径。少年质朴而不凋谢，这是长寿的基础，但人们嫌弃他神采不显露；孩童时期机神灵动，这是尊贵的征兆，但人们嫌弃他过于浑厚而缺乏雕琢。这中间一半由天定，一半由人为，后天的修养功夫，不知要费多少小心谨慎，然后才能凝聚福气而延长寿命。所以在得志之后，既然知道这身体是上天寄托的躯壳，自然应该保养精气、吝啬精神，以报答上天的眷顾。如果女子爱欲铺满床席，男子欢愉尽情发泄，耗尽自身固有的精气，转而依赖药物滋补，急于在眼前看到效果，致使无知的小人得以暗中操弄祸害人的手段，以图快速获利。虽然前代的覆辙皆如此，但当今时代更加严重罢了。大概现在太平景象变为繁促，世运已从火化（指气候或运势偏热），再用躁急的药物来辅助它，哪里能不使死亡接踵而至呢？这个道理只有岐伯和黄帝阐述得非常详细，只是仕宦人家不肯细心探究罢了。经文说：“凡阴阳之道，阳密乃固，两者不和，如春无秋，如冬无夏。”因此顺应它，这就称为圣人的法度。这段经文被以前的注解所埋没，不知道这是明确说明圣人在男女交合之际，其交会的方法法度，不过是使阳气秘密固守，从而坚固不泄而已。然而阴阳贵在相互调和，有春无秋，就是没有阴；有冬无夏，就是没有阳。所以圣人只是调理偏颇，使之归于和谐，这仅仅是交会的法度罢了。夫圣人拥有太和元气，生机自然掌握在自己手中。我看那调琴弄瑟、敲钟击鼓，即使是闺阁中女性的性情也能和谐，何况是自己的血气呢？通过礼乐陶冶教化，仁义潜移默化，即使是百姓万物的富足可以坐享其成，何况是个人的子嗣繁衍呢？所以凡是打算广延后代的人，用药的标准，只取纯正以召唤和谐，不取杂霸以引发乖戾。而且经文又说“阴平阳秘”四个字，尤其足以互相阐发其含义。大概阴得到平衡，而没有过与不及，然后阳才能得到秘密固守，而不走泄。这可见阳的秘固，是神圣交会所首要重视的。然而想要阳的秘密固守，就必须把权柄给予阴，正因为阳根源于阴，培养阴就是培养阳的基础。现在的人用峻烈猛烈的药物，劫尽阴精，以为是在培补阳气，再加上房事的重度消耗，逐渐导致骨髓消减、肌肉消瘦、神志昏沉、气息夺失、毛发枯槁、面色夭折，还不知道是被药物所误，真是令人痛惜啊。曾经见到一位姓宋的浙江医生，在京师制成大颗药丸，遍送仕宦人家，托名是用脐带胎发制成，其实里面用的是炼过的硫磺。服用后让人阳道骤然坚硬可喜，不久燥病百出。我家乡的各位老前辈遭受其祸害的，历历可数。最近游历鹿城，听说张鸿一孝廉，因为进服红铅损伤脑部，导致日夜精液流出不止。大概脑为髓海，脑热则全身之髓都奔涌而出，最终热邪未除而髓先枯竭，导致骨痿难以行走。到了娄过天如先生的旧宅，看见鼻中浊涕，凡是滴落在板壁上的，颜色深黄，渗入木头中，刷洗不掉。询问原因，也是由于服用种子壮阳热药所致。后来因为伤风小病，竟然致死。唉！脑热已极，蒸腾鼻涕变黄，从鼻子排出的热气，尚且能渗透木头，竟不省悟，直到热极生风，还治疗外表而不治疗内里，还有什么可说的呢？我乡刘石闾先生，服用热药而患上消渴病。医生邓橘存，坚持让他服用六味地黄汤一千剂，果然见效。这是因为得到了“壮水之主，以制阳光”的宗旨。高邮袁体仁的种子经验方，都用阴阳两平的药，大概是得了“阴平阳秘”的宗旨。这位老人精通医理且审慎用药，因此一并表彰他。又有方士取黑铅的水，名为神水金丹来迷惑人。凡是痰火之病，初时得到其下行的力量，也觉得稍感爽快，却不知道铅性至燥，反而导致劫耗阴精，危害更大。又有用蒸脐的药，名为彭祖接命之法。脐是人的命根，用麝香、硫黄、附子等大热散气的药，加上艾火蒸灼，幸好没有扰动真气，尚无大害；如果蒸动真气，使其散越不收，扰乱不宁，就会迅速致死。听说娄中的老医穆云谷，常教诲人说：蒸脐这一方法，只有损害没有益处，绝对不可行。这话真深刻啊，也一并表彰。胡卣臣先生说：难以生育的原因有五种。一是性格偏激苛刻，喜欢揭发别人的隐私；二是喜好洁净，遇到事物多有不适意之处；三是吝啬，持金钱不让漏出一丝一线；四是喜欢男宠，非其所用，导致肝筋急伤；五是多服热药，烧灼真阴直至耗尽。嘉言（喻昌自称）认为此论，曲折畅达经旨，以破除方士的谬误，打破轻信者的迷惑，真是救世的良药啊。
Human life possesses the joy of nature, the joy of status, and the joy of physical health. The joy of nature is like spring in all four seasons, with all things sharing one body. Although the dwelling may be desolate and sparse, joy remains. Although the five senses may be incomplete, joy remains. Although residing among barbarians or facing disasters, joy remains. In the streams, mountains, wind, and moon, as long as I am present, I am the master; regarding trees, stones, birds, and fish, treating them as close friends is sufficient. Why indulge in sexual passions on the pillow and bed, indulging in licentiousness? Even the Creator cannot exert his manipulations. As for the joy of status and the joy of longevity and health, only those with abundant fortune can possess both. Generally, attaining nobility and attaining longevity seem to have separate origins. Youthful simplicity without fading is the foundation of longevity, yet people dislike its lack of conspicuous brilliance; childhood agility and flowing spirit are signs of nobility, yet people dislike its excessive simplicity and lack of refinement. This lies halfway between heaven and human effort. The work of后天 (post-heaven) cultivation requires untold caution before one can condense auspiciousness and prolong life. Therefore, after achieving success, knowing that this body is entrusted by Heaven, one should preserve essence and conserve spirit to repay Heaven's favor. If one fills the bed with female love and exhausts male pleasure, depleting one's inherent essence and relying on medicinal herbs, seeking immediate effects, it allows ignorant villains to secretly employ methods of harming people to gain quick profits. Although past dynasties have seen such ruins, the current era is even more severe. Currently, the image of peace has turned into busyness, and the world's fortune has shifted towards fire (heat). Adding impetuous medicines to this, how can death not follow closely? This principle was explained in detail by Qibo and Huangdi, but officials are unwilling to investigate carefully. The classic states: "In the way of Yin and Yang, when Yang is secret/firm, it becomes solid. If the two do not harmonize, it is like having Spring without Autumn, or Winter without Summer." Therefore, following this is called the standard of the Sage. This passage was buried by previous annotations, failing to realize it explicitly states the Sage's method of intercourse: merely ensuring Yang remains secret and firm so it does not leak. However, Yin and Yang must harmonize. Having Spring without Autumn means no Yin; having Winter without Summer means no Yang. Thus, the Sage only adjusts imbalance to return to harmony, which is merely the method of intercourse. The Sage holds the Great Harmony Primordial Qi, grasping vitality naturally. Observing tuning zithers and playing lutes, even the temperament of women in the inner chambers can harmonize, let alone one's own blood and qi. Through ritual and music education, benevolence and righteousness gradually influence, even if the prosperity of people and things can be achieved effortlessly, how much more so for one's own offspring? Therefore, anyone planning to expand their lineage should use medicine with the standard of purity to summon harmony, avoiding eclectic harshness that causes deviation. Furthermore, the phrase "Yin Ping Yang Mi" (Yin balanced, Yang secret/firm) further elucidates this meaning. When Yin is balanced without excess or deficiency, Yang can remain secret and firm without leaking. This shows that the secrecy of Yang is the primary concern in sacred intercourse. To achieve the secrecy of Yang, power must be given to Yin, precisely because Yang roots in Yin; cultivating Yin is cultivating the foundation of Yang. Today's people use harsh and fierce medicines to rob away Yin, thinking they are nourishing Yang. Coupled with heavy consumption in the bedroom, this gradually leads to bone marrow depletion, flesh wasting, mental confusion, qi loss, hair withering, and premature aging, yet they do not realize they were misled by medicine. How sorrowful! I once saw a Zhejiang doctor surnamed Song who made large pills in the capital, distributing them to officials under the name of umbilical cord and fetal hair, but actually containing refined sulfur. It caused sudden and pleasant erection, but soon numerous dryness diseases emerged. Many elders in my hometown suffered from this, clearly identifiable. Recently traveling in Lucheng, I heard that Xiaojuan Zhang Hongyi damaged his brain by taking Red Lead (Hongqian), resulting in continuous nocturnal emission day and night. The brain is the Sea of Marrow; brain heat causes all marrow in the body to rush out. Ultimately, heat remains while marrow is exhausted, leading to bone weakness and difficulty walking. At the old residence of Mr. Lou Guotianru, I saw turbid nasal discharge dripping on wooden panels, deep yellow in color, penetrating the wood, impossible to scrub off. Inquiry revealed it was caused by taking seed-enlarging hot medicines. Later, due to a minor cold, he died. Alas! Brain heat is extreme, steaming mucus into yellow; the heat exiting the nose penetrates wood, yet he did not awaken until heat generated wind, still treating the exterior rather than the interior. What more can be said? Mr. Liu Shilu from my hometown developed Xike (wasting-thirst disease) from taking hot medicines. Doctor Deng Jucun insisted he take Liuwei Dihuang Tang (Six-Ingredient Rehmannia Decoction) for a thousand doses, which proved effective. This followed the principle of "strengthening the master of Water to control the brightness of Fire." Yuan Tiren's empirical formula for seeds from Gaoyou used medicines balancing both Yin and Yang, deriving from the principle of "Yin Ping Yang Mi." This elder was skilled in medicine and prudent with drugs, so I commend him. Another alchemist took water from black lead, calling it Shen Shui Jin Dan (Divine Water Golden Pill) to deceive people. For phlegm-fire diseases, initially experiencing its downward force feels slightly refreshing, but one does not know lead is extremely drying, causing further Yin robbery, resulting in greater harm. There is also the method of steaming the navel, named Peng Zu's Life-Extending Method. The navel is the root of life. Using large hot, qi-scattering drugs like Musk, Sulfur, and Aconite, plus moxa fire to steam and burn, fortunately, if true Qi is not disturbed, there is little harm. If steaming agitates true Qi, causing it to scatter and not gather, creating chaos and unrest, it leads to rapid death. I heard Old Doctor Mu Yungu from Lou often taught: Steaming the navel method has damage but no benefit, absolutely不可行 (not feasible). Profound words! I also commend this. Mr. Hu Youchen said: There are five reasons for difficult conception. 1. Personality is harsh and critical, liking to expose others' secrets. 2. Obsessed with cleanliness, finding many things unsuitable. 3. Stingy, holding money tightly without letting a thread leak. 4. Preferring young male prostitutes, using them improperly, injuring liver tendons. 5. Taking too many hot medicines, scorching true Yin until exhausted. Jiayan (Yu Chang's courtesy name) believes this discussion thoroughly expounds the classic principles, refuting alchemists' fallacies and breaking the confusion of the credulous. It is truly a medicine for saving the world.
