脉诊虽然是中医四诊（望、闻、问、切）之一，但其精微玄妙之处，并非粗劣的医生和庸俗的医术所能推测。晋代王叔和曾说：“心中容易理解，但指下感觉却难以阐明。”意思是把沉脉误认为伏脉，治疗方法就会完全错误；把缓脉误认为迟脉，病人立刻就会陷入危殆境地。更何况还有多种脉象出现在不同疾病中，即“异病同脉”的情况呢？由此可见，辨别脉象是不容易的。我是什么人，敢撰写脉象辨析之作？然而道理虽然难以辨析，但从上古的神圣医家到历代的名宿，虽然兼用望、闻、问三法，却没有舍弃切脉而能施展其巧妙医术的。我又不得不为之辨析。所谓辨析，并不是敢于在古人未曾阐发的旨意上妄加一说。古人的言语简朴平实、意淡含蓄，大多隐晦不易通晓。我则将其辨析得显明，使深奥隐秘的精妙之处，清晰得如同观看火焰一样明白。
到了后世的儒医，各自竭尽所学，广泛搜集各种版本，人人持有一说，让人无所适从。我则进行辨析，使其依据经典分门别类剖析，不至于造成混乱，这是第一大略。从第二辨到第七辨，遵循宗伯仁所论述的六脉，并阐述其所统摄的共二十九种脉象。每种脉象都加以注释，说明其阴阳属性，描绘其形象，像芤脉、动脉、牢脉、革脉这些最难明了的脉象，都有确切的含义可以探寻。从第八辨到第十二辨，则详细叙述十二经脉的源流，不仅详尽描述脉象所经过的部位以及诊脉的方法，例如辨析肺经时，则阐述肺的形体、肺的功能、肺的性情、肺所受六淫（风、寒、暑、湿、燥、火）和七情（喜、怒、忧、思、悲、恐、惊）的伤害，以及肺之积、肺之败，不仅知道肺的脉象，还穷尽肺的含义。心、脾、肝、肾也是如此。而对于胞络和三焦，以往感到困惑不解的地方，尤其进行了极致的开示和解析。从第十四辨到第三十二辨，则探究脉象变化中的奥妙。有完全取法诸书的，则标明其条目。即使是粗劣的医生和庸俗的医术者，阅读此书也应当有所领会。然而我不敢自认为没有遗漏。姑且以此请天下有识之士指正，希望那些知道我留心于此道的人，或许肯惠然赐教。
Although pulse diagnosis is one of the Four Diagnostic Methods (Inspection, Auscultation-Olfaction, Inquiry, and Palpation), its subtlety and profundity cannot be surmised by crude practitioners or mediocre skills. Wang Shuhe of the Jin Dynasty stated, "It is easy to understand in the mind, but difficult to clarify under the fingers." This refers to mistaking the Chen (Deep) pulse for the Fu (Hidden) pulse, leading to completely erroneous treatment; or mistaking the Huan (Moderate/Relaxed) pulse for the Chi (Slow) pulse, causing immediate peril to the patient. Furthermore, how much more complex is it when multiple pulse presentations appear in different diseases (Yi Bing Tong Mai)? Thus, differentiation is not easy. Who am I to dare write a treatise on pulse differentiation? However, although the principles are difficult to differentiate, from the ancient divine sages to famous masters of successive dynasties, although they employed Inspection, Auscultation-Olfaction, and Inquiry, none could apply their skill without relying on Palpation (Qie). Therefore, I am compelled to differentiate them. By "differentiating," I do not dare to arbitrarily add new interpretations to the unexpressed intentions of the ancients. The words of the ancients were concise, plain, and subtle, often implicit and hard to comprehend. I differentiate them to make them explicit, so that the profound mysteries become as clear as observing fire.
Later Confucian physicians, each expending their learning and extensively seeking various texts, held individual theories, leaving readers at a loss for direction. I differentiate them to ensure they are analyzed according to classics, preventing confusion. This constitutes the first general outline. From the Second Differentiation to the Seventh Differentiation, following Zongbo Ren's discussion of the Six Pulses, I elaborate on the twenty-nine pulses collectively governed by them. Each pulse is annotated with its Yin-Yang attributes and described in imagery. Even the most difficult-to-understand pulses, such as Kong (Hollow), Dong (Fluttering), Lao (Firm), and Ge (Leather), have precise meanings to be found. From the Eighth Differentiation to the Twelfth Differentiation, I detail the origins and flows of the Twelve Meridians. Not only are the pathways of the pulses and methods of diagnosis described in detail—for example, in differentiating the Lung Meridian, I discuss the form, function, nature, and temperament of the Lung, injuries caused by the Six Evils (Wind, Cold, Summer-heat, Dampness, Dryness, Fire) and Seven Emotions (Joy, Anger, Worry, Pensiveness, Grief, Fear, Fright), as well as Lung accumulations and failures—I also exhaust the meaning of the Lung beyond just its pulse. The same applies to the Heart, Spleen, Liver, and Kidney. Particularly regarding the Pericardium Collateral (Baoluo) and Sanjiao (Triple Burner), which were previously sources of confusion, I provide extreme clarity. From the Fourteenth Differentiation to the Thirty-Second Differentiation, I explore the profound changes within pulse patterns. Where I fully adopt content from other books, I mark the headings. Even crude practitioners may gain insight from reading this compilation. However, I dare not claim it is flawless. I submit this to the knowledgeable world for correction, hoping that those who know I have devoted attention to this art might kindly offer instruction.
