Chapter 6 of 13
脉经
The core of Volume 4 of the Mai Jing concerns the localization of pulse diagnosis, pathological conditions indicated by pulse images, the concordance or discordance between pulse and symptoms, and prognosis determination. The ancients divided pulse positions into the Three Sections and Nine Indicators: the Three Sections being cun (inch), guan (bar), and chi (cubit); the Nine Indicators being the further division of each section into Heaven, Earth, and Human, used to examine the upper, middle, and lower regions of the body. A large portion of this volume addresses one question: What pulse images, combined with what symptoms, indicate the disease is progressing favorably or unfavorably?
The opening of Volume 4 discusses the localization of the Three Sections and Nine Indicators and common pulse images, followed by descriptions of the upper, middle, and lower sections and the diseases above the chest and diaphragm, in the epigastric and abdominal regions, and below the lumbar region that they indicate. This is followed by a discussion of chi-skin diagnosis (chi fu zhen)—examining the cold, heat, smoothness, roughness, tightness, or laxity of the skin over the chi region of the forearm to assist in determining disease location and nature. Subsequent chapters shift to pulse images and their indications in miscellaneous diseases, syndromes of qi exhaustion of the visceral organs, pulses contrary to the four seasons, the depleted (sun) and surging (zhi) pulses, pulse cessation and times of death, pulses determining survival or death in hundred diseases, and determining survival or death through the vacuity and repletion of the three-section pulses.
The frequently occurring terms "death," "survival," "treatable," and "difficult to treat" reflect ancient physicians' experiential language for prognostication based on pulse images. These are not precise predictions in the modern sense. In study, they should be understood as the ancients' "risk stratification" approach to observing critically ill conditions, and should not be literally applied to modern judgments of life and death.
This chapter establishes the framework: the Three Sections are cun, guan, and chi; the Nine Indicators are the further division of each section into Heaven, Earth, and Human. The upper section examines the area from the chest to the head; the middle section, from below the diaphragm to the qi thoroughfare; the lower section, from the qi thoroughfare down to the feet. Pulse images such as floating (fu), sunken (chen), firm (lao), bound (jie), slow (chi), rapid (ji), slippery (hua), and rough (se) each have their names, and one must observe their changes separately to know where the disease originates; when using acupuncture and moxibustion, one similarly relies on this pulse-based localization.
The ancients held:
The ancient understanding of the normal pulses of yin and yang is: the chi pulse belongs to yin, and yin pulses are normally sunken and slow; cun and guan belong to yang, and yang pulses are mostly floating and rapid. Respiration and pulse activity correspond: the exit of qi is movement (dong), and its entry is breath (xi), so yin and yang pulses each have their normal frequencies of beating.
Regarding exterior-interior pulses, the ancients considered cun and chi as exterior, and guan as interior. If the guan pulse alone is abruptly interrupted and cun and chi cannot be linked, it is called "yin exhaustion" or "yang exhaustion," which was considered a critical sign. Another important analogy is proposed: when the upper section has no pulse but the lower section still has pulse, this is like a tree whose branches and leaves have withered, yet as long as its roots remain, it still has vitality. Therefore, the chi pulse is considered the "root."
This chapter also explains specially: some people may have a level (normal) cun-kou pulse yet die, because the "origin of generation qi" has failed. The origin of generation qi is not the root of the twelve channels, but is the dynamic qi between the kidneys, also known as the Palace of Life (Mingmen) , considered the foundation of the five viscera and six bowels, the root of the twelve channels, the gate of respiration, and the origin of the triple jiao. This understanding is an important source of the later Mingmen doctrine.
Following this, the text borrows Qi Bo's explanation of the relationship between form, qi, and pulse: those with strong form but a fine pulse, with insufficient qi to breathe, die; those with emaciated form but a large pulse, with excessive qi in the chest, die; those in whom form and qi correspond live. Additionally, the four seasons and yin-yang are combined with pulse images to determine the time of death, such as: in winter, the deep, fine, and faintly isolated yin pulse indicates death at midnight; in summer, a surging, restless, and panting rapid yang pulse indicates death at noon. These belong to the ancients' "correspondence of heaven and human" prognostic reasoning.
The latter half of the chapter elaborates on chi-skin diagnosis: conditions of the skin of the chi region—tight (ji), lax (huan), small (xiao), large (da), slippery, and rough—tend to correspond with similar qualities in the pulse. Those skilled in diagnosing the chi skin need not wait to examine the cun-kou; those skilled in examining the pulse have no need to wait for color observation; he who can combine these methods is an "honored physician." Examples:
The chapter concludes with a summary based on the divisions of cun-kou, guan-upper, and chi-center: any pulse that appears with characteristics such as floating, sunken, slippery, rough, stringlike, or tight—in the cun-kou indicates diseases above the diaphragm, in the guan indicates diseases from the stomach downward, and in the chi indicates diseases from the kidneys downward. When the cun-kou pulse is slippery and slow, neither sunken nor floating, neither too long nor too short, this indicates there is no illness. This is followed by a list of various pathoconditions indicated by the detailed pulse presentations of the cun-kou, guan, and chi positions.
This chapter is a compilation of pulse images indicating diseases, correlating singular and compound pulses with pathological conditions. For example:
The original text also mentions therapeutic approaches: stringlike-slow conditions are suited to warming medicinals, tight-rapid may benefit from promoting perspiration, and stringlike-small-tight may benefit from purgative/draining therapy. These belong to the logics of ancient therapeutic judgments and are provided for scholarly research only, not as guides for medicinal administration.
This chapter records the manifestations and the traditionally recorded latencies to death under the "exhaustion of qi" of the five viscera, six bowels, sinews, flesh, and bones. This content deals directly with prognosis, distinguishing survival from death. Examples:

# Divination — Learning Material for Volume 4 of the *Mai Jing*
## Overall Paraphrase
The heart of Volume 4 of the *Mai Jing* concerns the **localization of pulse diagnosis, the pathological conditions indicated by different pulse qualities, and the concordance or discordance between pulse and symptoms for prognosis**. The ancients divided the pulse into the **Three Sections and Nine Indicators**: the Three Sections being *cun* (inch), *guan* (bar), and *chi* (cubit); the Nine Indicators being the further division of each of these into Heaven, Earth, and Human, to examine the upper, middle, and lower regions of the body. A significant portion of this volume seeks to answer the question: **What pulse images, combined with what symptoms, indicate that the disease is trending toward recovery or toward deterioration?**
The opening of the volume establishes the locations of the Three Sections and Nine Indicators and the common pulse forms. It then describes the **upper, middle, and lower sections** and the ailments they each govern, from above the chest and diaphragm down to the epigastrium and abdomen, and below the waist. This is followed by a discussion of **diagnosis by the skin of the chi region** (the forearm's ulnar-side skin), where cold, heat, moisture, dryness, tension, and laxity help assess the location and nature of the illness. Later chapters address **pulse manifestations in miscellaneous diseases**, **progressive exhaustion of a visceral system's qi**, **pulses contrary to the four seasons**, **the "atrophic" (sun) and "excess" (zhi) pulses**, **pulse cessation patterns, rate, and prognostic windows of death**, **mortality and viability assessments across various diseases**, **and using vacuity and repletion of the three-section pulse to project outcomes**.
Throughout, repeating terms such as "death," "survival," "treatable," and "hard-to-treat" convey the ancient physicians' clinical experiences, a kind of loose "risk classification" for critical patients. **They must not be read as modern, exact predictions.** Learning from these passages requires viewing the text deliberately, as historical expression, not as practical guidance for today's judgments on prognosis or viability.

## Commentary on the Chapters
### I. Chapter 1: Distinguishing the Pulses of the Three Sections and Nine Indicators
This chapter establishes the structural principles: **the three sections being cun, guan, and chi; the nine indicators being Heaven, Earth, and Human within each position**. **The upper section observes above the chest and up to the head; the middle section observes from below the diaphragm to the 'qi street' (qijie); the lower section observes from the qi street downward to the feet.** The pulse names—floating, sunken, firm, bound, slow, rapid, slippery, rough—each correspond to certain pathological characteristics, and they must be examined over time: in tracking their development, one learns where affliction began. Meanwhile, examination of pulse serves also of acupuncture—where localizing the disease using the three positions determines key points alongside their precise route-channels.
The ancients noted:
- **Upper-section traces**: firm, bound, sunken, or slippery possibility... breath substances bank somewhat; if the associated feels faint/thready, think disturbances... abdomen tight while supine–chills, voice/hacking, cough–if pulsing can't descend-and harsh heat-lifting/coursing at ceph… "philtrum draws." th.

1. **Three Regions and Nine Indicators is a diagnostic method based on "location"**
The most important framework of Volume IV is: **the inch, barrier, and cubit positions correspond respectively to the upper, middle, and lower burners**, with each position having superficial and deep layers. The ancients did not merely observe the speed of the pulse, but determined the disease location by identifying "which position shows an abnormal pulse pattern."
2. **Pulse and symptoms are mutually corroborated; the pulse is never viewed in isolation**
The original text always presents pulse patterns together with symptoms, such as "fine, faint, and weak pulse, with abdominal pulling pain upon lying down, headache, and cough," indicating that the ancients believed the pulse must be interpreted in conjunction with symptoms—a single pulse pattern alone cannot determine a disease.
3. **Emphasis on stomach qi, spirit, and root**
Volume IV repeatedly stresses that the pulse must have a "root," especially the cubit pulse and the moving qi between the kidneys. If the pulse possesses stomach qi, root, and spirit, then even a severe illness may be survivable; if the pulse lacks root and stomach qi, the condition is critical. This is the core criterion of traditional Chinese pulse diagnostics.
4. **Harmony between constitution and qi is auspicious; contradiction between them is ominous**
"A stout body with a fine pulse" or "a thin body with a large pulse" both represent disharmony between the physical constitution and qi, which the ancients regarded as danger signs. This principle remains valuable at the macroscopic clinical level today: whether the patient's overall state is consistent with the pulse pattern is an important reference for assessing the severity of illness.
5. **Correspondence between the four seasons, the Five Phases, and pulse patterns**
Volume IV integrates seasons, organs, and pulse patterns, reflecting the concept of "correspondence between heaven and humans." Under normal conditions, the pulse of the organ corresponding to the prevailing season appears first; if the pulse of another organ appears instead, the condition is considered grave. This theory has systematic value, but its specific prognostic calculations should not be directly applied in modern practice.
6. **The depleted and excess pulses are classifications of excessively slow and rapid pulses**
The ancients called a pulse rate that was too rapid "excess" (zhi) and one that was too slow "depletion" (sun), each further classified into grades such as departing from the channels, loss of essence, death, and exhaustion of life. This is a very early concept of "risk stratification for abnormal pulse rates," expressed in ancient terminology.

## Modern Perspectives 🌟
- **Pulse diagnosis has empirical value but requires objectification**
Modern research has attempted to use techniques such as pressure sensors and photoplethysmography to convert pulse patterns into pulse graphs, and some pulse patterns—such as wiry, slippery, and fine pulses—have a certain hemodynamic basis. However, traditional descriptors such as "floating, sinking, rapid, slow, slippery, and choppy" still cannot be fully mapped one-to-one onto modern physiological indicators.
- **"Life and death" and "time of death" are ancient prognostic views and cannot be directly adopted**
The extensive content in Volume IV about "death on a certain day" or "death at a certain age" is a product of combining medical experience with Five Phases calendrics around the Han dynasty. It reflects an intuitive risk awareness that "severe illness portends poor prognosis," but its specific timeframes are not reproducible in modern clinical practice. When studying it, one should adopt its approach of "judging favorable versus unfavorable outcomes" while discarding its mechanical calculations.
- **Some observations have a sound core**
For example:
- Pulse rates that are too rapid, too slow, or irregular with skipped beats may correspond to tachyarrhythmias, bradyarrhythmias, premature beats, atrial fibrillation, and other arrhythmias;
- "A stout body with a fine pulse or a thin body with a large pulse" can be understood as a mismatch between cardiac function, circulatory status, and body habitus;
- "Hot cubit skin with a full and agitated pulse indicates febrile disease" resembles a comprehensive observation of fever, peripheral circulation, and infectious diseases;
- "Cubit skin rough like the scales of a dried fish" bears some similarity to dry skin, dehydration, or skin changes in certain chronic diseases.
- **"Strange pulses" are primarily descriptions of pulses in critical conditions**
Patterns such as "leaking roof," "sparrow pecking," or "boiling water in a pot" were called "true visceral pulses" or "death pulses" in ancient times. Today they are generally understood as pulse manifestations in severe heart failure, arrhythmias, or terminal circulatory collapse. These descriptions have an observational clinical basis, but there is no need to mystify them.

## Insights for Health Preservation ⚡
- **Observing the pulse suggests "harmony between form and qi"**
In daily life, one can experience that when the body is in good condition, the spirit, physical strength, complexion, and pulse tend to be coordinated; if one is chronically fatigued, emaciated, palpitated, or has cold extremities, attention should be paid to the overall state of qi and blood, rather than pushing through.
- **Live with moderation and protect "root qi"**
Volume IV repeatedly emphasizes the cubit pulse and the moving qi between the kidneys as the root of life. In modern life, one should especially avoid chronic sleep deprivation, excessive overwork, and irregular eating, as these all deplete "root qi," making one prone to fatigue, sensitivity to cold, and slower recovery.
- **Align with the four seasons and maintain a steady routine**
The ancients spoke of spring growth, summer flourishing, autumn harvest, and winter storage, and the pulse should also harmonize with the seasons. Daily routines can be modestly adjusted according to the season—such as sleeping early and rising late in winter, or guarding against heat and nourishing the heart in summer—but these should not be applied mechanically.
- **Do not self-diagnose or apply ancient "critical pulse" criteria**
If one notices palpitations, irregular pulse rhythm, marked cold sensitivity or fever, weight loss, or fatigue, one should seek examination at a regular medical institution. **The pulse is only one part of overall assessment and cannot replace electrocardiography, blood pressure measurement, blood tests, or other modern evaluations.**
