果报。故于诊视之中。备述孙真人钱医丞嘉言善行。以为吾徒勉。)
First. Spread three fingers broadly. (When initially taking the pulse, there is no need to immediately seek the three positions; rather, spread three finger-widths wide, starting from the outside of the Chi position towards the inside of the forearm, slightly moving upward to probe and feel. One must clearly understand the exact location of the skin before one can diagnose the three pulse positions. The *Nan Jing* (Classic of Difficult Issues), Chapter 13, states: "If the pulse is rapid, the skin at the Chi position is also rapid," and similar phrases. Ancient practitioners first examined the three pulse positions and then correlated them with the condition of the skin at the Chi position. By 'skin at the Chi position,' it refers to the epidermis on the inner aspect of the arm muscle, outside the third position, the Chi pulse. At this location, arterial pulses are not diagnosed; instead, the skin is merely tested for temperature and texture—whether rapid, tense, slow, choppy, or slippery—hence the reference to the skin at the Chi position. The reason for understanding the skin at the Chi position is to use this method to first ascertain the patient's body heat or cold, corpulence or emaciation, and the density or looseness of the skin. In this way, the depth of the disease (superficial or deep), its location (internal or external), and the duration (recent or chronic) can be identified. Master Ding said: A rapid sensation in the inner forearm indicates hot skin; a tense sensation indicates fullness and excess in the meridians; a slow sensation indicates wasting of the muscles. Therefore, I have stated that 'rapid' refers to the flesh; if the skin is hot, the disease is also a heat pattern; if the skin is not hot, the disease is not a heat pattern. Other conditions, such as extreme cold or neither cold nor heat, can be inferred by analogy. 'Tense' refers to solid flesh and tight skin, indicating a recent illness where Ying and Wei Qi have not yet been depleted. 'Slow' refers to loose flesh and skin, indicating a chronic illness where Ying and Wei Qi have already been depleted. 'Choppy' refers to non-smooth skin, closed pores, and absence of sweat, which is correct. 'Slippery' refers to lubricity, open pores, and excessive sweating, which is correct. The ancients did not express their meaning fully; listing these five cases reveals the general principle. Alternatively, using one finger instead of three, pressing down from top to bottom, section by section, is also acceptable. However, this method cannot reveal the condition of the skin at the Chi position and is therefore insufficient as a standard. Regarding the skin at the Chi position, whether male or female, observing one hand is sufficient.)
Second. Align the three positions with the high bone. (In both hands, there is a prominent bone behind each palm. To diagnose the three positions, first use the middle finger to locate the high bone, naming this point Guan (Gate). Once the high bone is found, slightly lift the middle finger, and use the index finger anterior to the high bone to take the Cun (Inch) pulse. After diagnosing the Cun position, slightly lift the index finger, lower the middle finger again to take the Guan pulse. After diagnosing the Guan position, slightly lift the middle finger again, and lower the ring finger posterior to the high bone to take the Chi pulse. During diagnosis, do not face the patient directly; stand slightly to the side, left or right. Maintain dignified demeanor, regulate nasal breathing, focus mental attention, and then slowly diagnose. If one is erratic or out of order, it is unlawful. Another view holds that for all pulse diagnoses, one should only place fingers after the breath has stabilized. The patient should remain silent and not speak; the practitioner should hold their breath and not talk, maintaining silence, reverence, and stillness, free from external distractions. Initially, press lightly (Floating) to observe; next, press moderately (Middle) to observe; next, press heavily (Deep) to observe; next, push the finger to the distal end to observe; next, push the finger to the proximal end to observe; next, push the finger outward to observe; next, push the finger inward to observe. The details are described in the previous section on finger movement techniques.)
Third. Establish the finger method based on ancient sources. (Masters Cui and Liu relied solely on the Floating, Deep, Slow, and Rapid pulses to determine Wind, Qi, Cold, and Heat patterns, using these four to generalize over a hundred diseases. Investigating these four, they originally applied only to miscellaneous diseases. If suddenly diagnosing Shanghan (Cold Damage) or exogenous diseases, there are aspects that do not apply universally. Now, adopting Zhang Zhongjing's Ping Mai Fa (Method of Calm Pulse Diagnosis) and combining it with the transmission of Cui and Liu, perhaps we can use both without regret. They stated: Floating indicates Wind, Deep indicates Qi, Slow indicates Cold, Rapid indicates Heat; this is the ancestral theory for miscellaneous diseases. They stated: Floating is exterior, Deep is interior, Slow is Zang, Rapid is Fu; this is the current determined method for diagnosing Shanghan. One must know that both Shanghan and miscellaneous disease diagnoses must take the Floating, Deep, Slow, and Rapid pulses as the root, yet each has its own categories and must not be confused. Only by mastering this manual can one read pulse books; otherwise, the study will be vague and unorganized.)
Fourth. Integrate into unity. (Having determined the disease pattern by previous methods, verify these methods against the disease pattern. Since knowing the disease through the pulse, and examining the pulse according to the disease, integrate and comprehend thoroughly, exploring repeatedly until the actual disease name is obtained and unified. Diagnosing the pulse is the most difficult task. There are cases where the pulse and disease correspond, and cases where they do not. There are diseases with pulses indicating easy recovery, cases cured immediately by treatment, and cases aggravated by treatment. The general principle is to use my simplicity to manage their complexity, and my single-mindedness to control their myriad changes. This is what is called the way of grasping one to manage ten thousand.)
Fifth. Observe form but do not be rigidly bound by it. (*Mai Jing* [Pulse Classic] states: Each of the Five Zang organs has specific sounds, colors, odors, and tastes, which should correspond to the Cun and Chi positions within the wrist. If they do not correspond, it is disease. From this, we know that observing form and color, and correlating them with the Cun and Chi positions, is an ancient method. For example, green complexion indicates Liver disease, and one should expect a Wiry and Tense Liver pulse. However, Zhang Zhongjing's methodology goes beyond merely observing the colors and pulses of the Five Zang organs. One must observe the patient's daily activities and movements, as well as various external symptoms, which can be known through observation (Wang). One must see with eyes and deduce with mind, gaining clear insight, before judging auspiciousness or inauspiciousness. Is it merely about distinguishing five colors of the Five Zang organs?)
Sixth. Listen to voice but do not be limited to sound. (*Huang Di Nei Jing* [Yellow Emperor's Inner Canon] says: Knowing through hearing is called Sage. Like observing color, it correlates with what the Five Zang organs govern, hence saying: listening to the five tones to distinguish disease. This approach is somewhat rigid. For instance, aphasia due to stroke indicates pathogen entering the Zang organs. However, there are cases of sudden aphasia without cause, absent pulse, which heal spontaneously without treatment; this is due to sudden rebellion of Qi. Although similar to stroke aphasia, the nature is different. Again, delirious speech in Shanghan indicates Yangming disease with dry stool in the Stomach, requiring purgation for cure. This differs from deficiency-type delirium where Zheng Qi is exhausted and spirit is scattered; purging in such cases causes severe deficiency. A mistake here leads to disaster instantly. Also, heavy voice and coughing are indeed signs of Cold pathogen, but can also result from Wind-Heat obstructing upwards, or consumption cough leading to loss of voice, resulting in Fei Wei (Lung萎/Flaccidity), a difficult-to-cure syndrome. Symptoms may be similar, but the underlying nature differs. Thus, the method of listening to voice cannot rely solely on the five tones Gong, Shang, Jue, Zhi, Yu to determine diseases of the Five Zang organs. One must listen carefully to the patient's speech and voice, the language used when the family seeks medical help, and all other bystander comments. Let it enter the ears and focus the mind; this is the true way of listening, which ancient methods could not fully encompass.)
Seventh. Speech must be reasonable. (Observation, Listening/Smelling, Inquiry, and Palpation are called Divine, Sage, Skillful, and Ingenious. Inquiry is essentially the third method, and Palpation is the fourth. Nowadays, society is not like antiquity; Palpation is placed first, while Inquiry is considered last. Patients suffering from illness not only do not speak, but even when asked repeatedly and earnestly, they finally do not answer, instead claiming the doctor is incompetent. Some even hide serious illnesses, troubling the doctor. The doctor is indeed troubled by you, but fails to realize that the body is also troubled by the doctor. What benefit is there? Nevertheless, a physician must value learning. Generally, after completing the examination, one should not immediately state the disease name, as hasty speech leads to errors. One should start with the observed pulse qualities, extensively cite classics as evidence, then proceed from shallow to deep, concluding with the disease pattern. It must be precise and accurate, not disjointed or arrogant. After discussing the symptoms, slowly ask about the patient's suffering. If the discussion is incomplete, allow the patient to explain in detail, then compare their account with your diagnosis, reconciling similarities and differences. In this way, Observation, Listening, Inquiry, and Palpation are all complete. Mutual trust and harmony between doctor and patient will be achieved, eliminating confusion and ensuring complete success.)
Eighth. Compassion to save all living beings. Sun Simiao said: When treating diseases, physicians must calm their spirits and stabilize their wills, having no desires or demands. Regardless of noble or base, rich or poor, treat everyone equally, as if they were close relatives. Do not look forward or backward, worrying about good or bad fortune, or protecting one's own life. Seeing the patient's suffering as one's own, feel deep compassion, do not avoid danger or hardship, devote oneself entirely to saving lives, and leave no trace of self-interest. This can be called compassionate salvation of all living beings. A Grand Physician who acts contrary to this is a great thief among sentient beings. Examining these words today, they hit upon the ailments of contemporary physicians. Luo of Hengyang said: Modern physicians often slander previous doctors, frighten patients, and intend to gain large bribes, which is extremely inhumane. In the past, when the Crown Prince was ill, imperial physicians could not cure him. The Eldest Princess mentioned that Qian Yi, coming from common roots, had extraordinary skills, and he was immediately summoned. He administered Huang Tu Tang (Yellow Earth Decoction) and the prince recovered. Emperor Shenzong asked how he could cure this illness. He replied: Using Earth to overcome Water, Wood achieves balance, thus Wind stops naturally. Moreover, the other physicians were also approaching a cure; I happened to coincide with the recovery. The Emperor was pleased with his response and promoted him to Vice Director of the Imperial Medical Bureau. Scholars who can adopt the heart of Qian Bo Du (Qian Yi) will do well. I believe medicine is a minor skill; if one does not seek profit or calculate merit, one is a benevolent person. If one worries about gain and loss, one will go to any lengths. Furthermore, those with unkind hearts will surely face karmic retribution. Therefore, in this diagnostic guide, I recount the virtuous words and deeds of Sun Simiao and Vice Director Qian to encourage my disciples.)
