人的身体就像天地一样。天地失去和谐，宇宙就会遭受灾殃；人体失去和谐，四肢就会产生疾病。主宰这一切的，在天地之间是君主，在人体之中则是心。
所以心是君主之官。君主如果失去了治理，宇宙就会发生灾难困厄；心如果失去了滋养，四肢就会产生疾病。消除宇宙的灾难困厄，只有依靠宰相的调和与燮理（协调处理）；治疗人体的疾病，也只有依靠医生的调和与燮理。所以说，做不了好的宰相，就做好的医生。然而，宰相如果施政失误，就会残害百姓；医生如果误治，就会残害生命。宰相和医生这两个角色，难道是可以轻易谈论的吗？
大概天地的九州，对应人体的九窍；天地的九野，对应人体的九脏。石头构成骨骼，泥土构成肌肉，江河成为血液，草木成为毫毛头发，道路成为脉络，风成为气，雨成为汗，雷成为声音。凡此种种，都说明人体没有不与天地相合的。天地有灾害，无不通过道路传闻；人体有疾病，无不表现在脉络上。所以治疗疾病，关键在于诊察脉象。
我当年在江城治理县邑时，官府中有很多奇特的疾病。我结识了张路玉先生，他诊察脉象、辨析证候，扶助正气、祛除邪气，反应迅速准确，如同槌击鼓面立刻发出声响一样。于是我问他说：“人体的脉络众多，为什么唯独通过两手手腕的脉象来决断病情呢？”他回答说：“两手的寸口脉，是心肺的关隘，是一身的主宰所在，就像君相的都城，天下的总会。所以天下的灾难无不起源于都城，一身的疾病无不表现在两手手腕的脉象上。”
人的六部脉象，就像朝廷的六部。天下的刑罚奖赏与惩罚，无不由此决定。然而他气宇轩昂、品格磊落，对脉理的论述卓越超绝，远远超越了一般常识。他能在指掌间运用天时，在须臾间决断生死，这又不是平庸之辈所能知晓的。没有经天纬地之才的人，不可以和他谈论医学。让他做优秀的宰相，又有什么不可以的呢？后来他以《脉学》一书索求序言，书名为《诊宗三昧》。我虽然不懂医学，但观看他论述天地阴阳的常规与变化，山川草木的脉理机理，灵机独发，无不贯通造化之理。我所说的“做良相”，确实是可信的。当时因为被征召赴京任职，忙碌无暇答应。如今因职务劳累，咳嗽旧疾复发，想到得不到良医，于是写下这几句话，邮寄过去以表达仰慕之情。
康熙己巳年（1689年），即墨后学晚辈郭撰
The human body is akin to Heaven and Earth. When Heaven and Earth lose harmony, the universe suffers calamities; when the human body loses harmony, the four limbs fall ill. The entity that governs this is the Sovereign in Heaven and Earth, and the Heart in the human body.
Therefore, the Heart serves as the Sovereign Ruler. If the Sovereign fails in governance, disasters and distress befall the universe; if the Heart lacks nourishment, diseases afflict the four limbs. To mitigate the disasters of the universe, one relies on the harmonization and coordination (Xielie) of the Prime Minister; to treat diseases of the body, one relies on the harmonization and coordination of the physician. Thus it is said: "If one cannot be a virtuous Prime Minister, one should be a skilled physician." However, if a Prime Minister misgoverns, he harms the people; if a physician treats incorrectly, he harms life. Can the roles of Prime Minister and Physician be taken lightly?
Consider that the Nine Provinces of Heaven and Earth correspond to the Nine Orifices of the human body; the Nine Fields of Heaven and Earth correspond to the Nine Zang Organs. Stones form the bones, earth forms the flesh, rivers and lakes become blood, grass and trees become hair and bristles, roads become meridians, wind becomes Qi, rain becomes sweat, and thunder becomes voice. All these demonstrate that the human body is in accordance with Heaven and Earth. Calamities in Heaven and Earth are inevitably reported via roads; diseases in the human body inevitably manifest through meridians. Therefore, treating disease hinges crucially on pulse diagnosis.
When I was governing the county in Jiangcheng, many strange diseases occurred within the yamen. There I met Mr. Zhang Luyu. His examination of pulses and differentiation of syndromes, his support of deficiency and expulsion of excess, were responsive and accurate like the immediate sound of a drum struck by a mallet. I asked him, "The human body has numerous meridians; why do you solely decide illness through the two wrists?" He replied, "The Cun positions of both wrists are the passes of the Heart and Lung, the masters of the whole body, just as the capitals of the Sovereign and Minister, or the central hub of the world. Hence, disasters in the world invariably originate from the capital, and diseases in the body invariably manifest at the two wrists."
The six pulses of a person are like the Six Ministries of the court. Punishments, rewards, and penalties in the world all stem from here. Yet, with his dignified bearing and upright character, and his outstanding theories on pulse analysis that far exceed common knowledge, he could manipulate the timing of Heaven and Earth under his fingertips and determine life and death in an instant. This is not something that can be understood by ordinary people. One who does not possess the talent to organize Heaven and Earth cannot discuss medicine with him. To make him a virtuous Prime Minister, who would say no? Later, he requested a preface for his book on pulse studies, titled *Zhen Zong San Mei* (Three Profound Secrets of Pulse Diagnosis). Although I do not understand medicine, observing his discussion on the constancy and variation of Yin and Yang of Heaven and Earth, and the pulse principles of mountains, rivers, grass, and trees, I saw his spiritual insight emerge uniquely, penetrating the creative forces of nature. My statement about being a virtuous Prime Minister is indeed confirmed. At that time, I was summoned to the capital for duty and was too busy to agree. Now, exhausted by official duties, my chronic cough has returned. Thinking that I cannot find a good physician, I write these few words and mail them to express my admiration.
