Yin-Yang Balance Analysis Framework

R — Original Text (Reading)

The Yellow Emperor said: Yin and Yang are the way of heaven and earth, the guiding principle of all things, the parents of change, the origin of life and death, and the residence of the spirit. When Yin prevails, Yang is diseased; when Yang prevails, Yin is diseased. When Yang prevails there is heat; when Yin prevails there is cold. When Yin is balanced and Yang is secure, the spirit is governed; when Yin and Yang are divorced, essence and qi are cut off.

— The Yellow Emperor/Qi Bo, Chapter 5 of the Great Treatise on the Correspondences of Yin and Yang, Chapter 3 of the Treatise on the Communication of Life with Heaven

I — Methodological Skeleton (Interpretation)

The Yin-Yang balance analysis method is a structured framework for diagnosing and correcting system imbalances.

Its core operations are divided into three layers:

Assign to Yin and Yang: Assign any phenomenon to the two opposites of Yin and Yang. Yang represents active, warm, outward, and excited; Yin represents passive, cold, inward, and inhibited. This is not labeling, but establishing a perspective of "looking at problems through opposites."

Determine excess and deficiency: Determine which side is excessive and which side is insufficient. "When Yang prevails there is heat; when Yin prevails there is cold"—imbalance necessarily manifests as symptoms on one side. The key is to distinguish whether it is "one side is excessive" or "the other side is insufficient," because the corrective direction is completely different.
Correct with opposites: When Yang is excessive, supplement Yin and suppress Yang; when Yin is excessive, supplement Yang and suppress Yin. The direction of correction is always to draw strength from the opposite side, not to directly suppress the excessive side.
The balanced state is the goal: "When Yin is balanced and Yang is secure, the spirit is governed"—when the system restores balance, function naturally becomes normal. Balance is not a static 50/50, but a dynamic mutual restraint.

The power of this framework lies in: any complex system, as long as it can be assigned to Yin and Yang, can be analyzed using the same set of logic.

A1 — Application in the Text (Past Application)

Case 1: Pathological manifestations of heat when Yang prevails

Problem: A person develops excited symptoms such as fever, thirst, and flushed face. How should their essence be understood?
Use of the methodology: Assign symptoms to Yin and Yang—heat, excitement, and outwardness all belong to Yang, so it is judged as "Yang prevails." According to "When Yang prevails there is heat; when Yang prevails, Yin is diseased," excessive Yang qi not only produces heat signs, but also consumes Yin fluids (body fluids are damaged).
Conclusion: On the surface it is "heat," but in essence it is a Yin-Yang imbalance—Yang is excessive and Yin is damaged.
Result: The treatment direction is not simply to cool down, but to "treat heat with cold" while also nourishing Yin, preventing excessive Yang from damaging Yin and leading to "divorce of Yin and Yang."

Case 2: The standard for a balanced person with even Yin and Yang

Problem: How is health defined?
Use of the methodology: Define health using the standard of Yin-Yang balance—"When Yin and Yang are even and balanced, so as to fill the body, and the nine indicators are as one, it is called a balanced person."
Conclusion: Health is not "absence of disease," but Yin and Yang in dynamic balance, nourishing the body, and the pulse conditions harmonious.
Result: This standard turns "balance" from an abstract concept into an operable diagnostic standard—judging whether Yin and Yang are balanced by whether the pulse conditions (nine indicators) are harmonious.

A2 — Trigger Scenarios (Future Trigger) ★

In what situations will users need this skill?

System Imbalance Analysis: The user describes a system exhibiting a contradiction of "one side too strong, one side too weak," such as a team with "too many pushers and not enough pullers," or a body with "internal heat but cold hands and feet."
Opposing Conflict Diagnosis: The problem is two opposing forces in confrontation—heat and cold, fast and slow, excitation and inhibition, expansion and contraction—and it is necessary to determine which is excess and which is deficient.
Confusion About Correction Direction: The user knows something is wrong in a certain aspect but is unsure whether to "strengthen the weak" or "suppress the strong," and needs to find the correct direction of intervention.

Language Signals (activate when these appear in the user's words)

"X on one side and Y on the other, feels very unbalanced"
"Always too much X, lacking Y"
"How do I judge whether to supplement or to drain"
"The system swings between two extremes"
"Excessive X causes the problem of Y"

Distinction from adjacent skills

Difference from five-elements-network : yin-yang balance deals withpolar oppositionrelationships (a single contradiction), while five-phase generation and restriction deals withmulti-element networksrelationships (a chain of five elements). When the problem has only two opposing sides, use yin-yang; when three or more elements influence one another, use five phases.
Difference from biao-ben-priority : yin-yang balance solves the "direction" problem (whether to supplement or to drain), while root and branch, acute and chronic solves the "sequence" problem (which to treat first and which afterward).

E — Executable Steps (Execution)

After the skill is activated, the agent should execute the following steps:

Assign to yin and yang: classify phenomena into opposing sides
- List all abnormal manifestations in the current system, and assign each one to the "yang side" (active/warm/outward/excited) or the "yin side" (passive/cold/inward/inhibited).
- Completion standard: all abnormal manifestations have been assigned to the yin and yang columns, and the definitions of the two columns are consistent (do not mix yin and yang from different dimensions).
Determine excess or deficiency: judge the direction of imbalance
- Count the number and severity of symptoms in the yin and yang columns, and determine whether it is "one side in excess" or "one side insufficient."
- Completion standard: clearly give a judgment—"X excess and Y deficiency" or "X deficiency causing Y to be relatively excessive"—and explain the basis for the judgment.
- Stop condition: if all symptoms are assigned to one side and no opposition can be formed, skip to step 3 and suggest that the user supplement information about the opposing side.
Correct using the opposing side: formulate the direction of intervention
- Based on the judgment of excess or deficiency, determine the direction of correction: if excess, suppress/drain it; if deficient, supplement/support it. The means of correction come from the opposing side—when yang is excessive, use yin (cooling/inhibiting/astringing); when yin is excessive, use yang (warming/activating/dispersing).
- Completion standard: give a clear direction of intervention (at least 1 specific action), and point out the expected state of balance after correction.

B — Boundary (Boundary) ★

Do not use this skill in the following situations

Pure binary opposition judgment (either this or that): Yin and yang are a dynamic balanced relationship, not a classification label of "either yin or yang." If the user's question is "Is A better or B better," this is a multiple-choice question, not yin-yang analysis.
Only a single variable: If the problem has only one aspect and there is no opposing side for reference (such as "how to improve efficiency"), you need to first find the opposing side ("efficiency vs quality"); otherwise the yin-yang framework cannot unfold.

Failure modes the author warns about in the book

Yin and Yang depart and separate: When the imbalance of Yin and Yang reaches its extreme, the two sides become completely disconnected, and "the essential qi is then cut off"—the system collapses beyond recovery. This means that correction must be carried out before the imbalance completely spirals out of control.
Severe cold then heat, severe heat then cold: Extreme imbalance can produce false appearances—when cold reaches its extreme, it instead manifests heat signs. One must not be misled by surface symptoms; one must trace back to the true direction of the imbalance.

The author's blind spots / limitations of the era

The Yin-Yang framework of the Suwen is built on natural philosophical observation and lacks the precise measurement methods of modern science. In scenarios requiring precise data (such as blood pressure and blood glucose values), the Yin-Yang framework should serve as an auxiliary perspective rather than a replacement for diagnosis.
The Yin-Yang dichotomy is sometimes overly simplified; systems in reality may contain multidimensional contradictions, and at such times it is necessary to combine the five-phase generating and overcoming network to expand the dimensions of analysis.

Adjacent methodologies easily confused with it

The unity of opposites in dialectics: Similar in form, but the Yin-Yang balancing method places greater emphasis on a holistic systems view and the operable step of "using the opposite aspect to correct," not merely philosophical analysis.
Balanced Scorecard: A business management tool that focuses on multidimensional balance, but it does not provide the operational logic of the Yin-Yang framework: "judging excess or deficiency + correcting with the opposite aspect."

contrasts-with: zheng-xie-assessment — Yin-Yang balancing handles the direction of excess or deficiency in "polar opposition" (whether to supplement or to drain), while healthy-evil deficiency-excess handles the balance of power between "self vs. external" (whether it is insufficient capacity or excessive pressure). The two are often used in sequence: first use Yin-Yang to judge the direction of excess or deficiency, then use healthy-evil to judge the strategy of deficiency or excess.
composes-with: seasonal-regimen — seasonal regimen is the concrete application of Yin-Yang balancing in the temporal dimension: nourish Yang in spring and summer (following the rising and growing of Yang qi), nourish Yin in autumn and winter (following the storing and hiding of Yin qi); in essence, it is adjusting the emphasis of Yin-Yang balance according to the seasons.
