TaixuanjingThe Canon of Supreme Mystery · 太玄經
Yang Xiong’s ternary image–number system: 81 figures for reading position, development, timing, and transformation with more gradation than a simple binary.
The working premise
81Figures of graded change
Ternary lines produce a finer map of emergence, stability, differentiation, and transition.
What this page covers
Beyond either/or.
Taixuanjing is a Han image–number canon associated with Yang Xiong. It reorganizes change through three-valued lines and 81 figures, creating a more graduated vocabulary of position and development.
Use it to distinguish stages inside change—not to add numerological decoration. The practical task is to locate the field, read the figure’s developmental quality, identify the operative position, and size action accordingly.
Ternary logic is useful because many conditions are neither simply open nor closed: they are emerging, mediated, or in transition.
Origins · conservative claims
A Han rethinking of change.
Yang Xiong
Associated with the Han thinker and writer Yang Xiong.
Late 1st BCE → early 1st CE
Composed within the intellectual environment of the Western Han transition.
In conversation with the Yijing
Builds an independent ternary architecture rather than merely copying hexagrams.
Graded situational reading
Maps pattern, timing, position, conduct, and development through image and number.
System architecture
Three values. Four positions. Eighty-one figures.
Ternary line values
Three line types create a spectrum of conditions instead of a single polarity.
Four stacked positions
Each figure arranges four places, allowing stage and role to change meaning.
Complete figure field
Three values across four positions generate 81 distinct configurations.
Appraisal sequence
Each figure unfolds through appraisals that refine timing and development.
Image
The image compresses a situational pattern into memorable form.
Number
Number orders the pattern, preserving sequence, proportion, and relation.
Minimal working grammar
Read three kinds of condition.
Do not reduce the three line values to simplistic good, neutral, and bad. Read them as different structural qualities within a developing field.
Coherent force
A line can express concentrated, continuous movement whose strength still depends on its position and season.
Differentiated force
A divided condition indicates separation, constraint, receptivity, or the need to coordinate parts.
Mediated force
A third value introduces gradation: transition, mixture, emergence, or a middle condition requiring finer judgment.
Field sequence
Use the system without number worship.
The figure should clarify position and movement—not replace observation or grant false certainty.
Operational use
Where ternary thinking helps.
Recognize the middle condition.
Separate “not ready” from “wrong.” A mediated state may call for preparation, coalition, or a smaller experiment.
Distinguish distance from rupture.
A relationship can be constrained, reorganizing, or testing boundaries without being simply secure or broken.
Stage transition deliberately.
When a system is between phases, protect continuity while introducing the next process at controlled amplitude.
Abstracted micro-cases
Better distinctions, lower regret.
Demand exists; readiness is partial
Read: mediated emergence. Move: release to one segment, protect service capacity, and delay the full campaign.
Authority is formal but not settled
Read: differentiated field. Move: build working alliances and prove one decision cycle before expanding force.
Neither commitment nor exit is clean
Read: transition. Move: define a bounded trial with explicit evidence for renewal or release.
Common traps
Keep the method clean.
- Binary relapse: do not force three values back into good versus bad.
- Number worship: calculation without situational definition is empty.
- Position neglect: the same quality changes according to role and stage.
- System mixing: do not bolt unrelated rules onto the figure.
- False precision: a rich model does not remove uncertainty.
Ethics & limits
Proportion. Records. Safety.
- Use image–number to clarify options—not to label people or excuse harm.
- Record the question, figure, position, action, horizon, and result.
- Never override law, engineering, medicine, safety, or accounting with symbolism.

The bottom line
Replace either/or with disciplined gradation.
Taixuanjing reads change through ternary structure: locate the position, name the developmental quality, size the move, and verify. For identity-aligned study, begin with your Day Pillar.
