This lesson turns a completed cast into a bounded written interpretation. Construction comes first; interpretation begins only after the inputs, arithmetic, hexagrams, and moving line are fixed.

Prerequisite: bring a complete cast with exactly one moving line. Your output is a three-sentence reading, confidence label, plausible alternative, stopping reason, and later review note.

The Reading Flow

Use this sequence:

  1. Name the primary hexagram.
  2. Name the changed hexagram.
  3. Identify the moving line.
  4. Assign Ti and Yong.
  5. Read the Five Phase relationship.
  6. If you have a named, sourced seasonal rule, record its result; otherwise skip this layer.
  7. Read the hexagram and line text.
  8. Separate observations, lineage rules, received text, and UAYA synthesis.
  9. Write three practical sentences and a confidence label.
  10. Record an alternative reading or inconclusive decision.
  11. Review the outcome later without deleting misses.

Ti/Yong First

Before judging favorable or unfavorable, assign Ti and Yong from the moving line.

TermRole
Tibody or subject; in this course, the trigram without the moving line
Yongfunction or matter in relation to Ti; in this course, the trigram containing the moving line

With one moving line, lines 1–3 make the lower trigram Yong and the upper trigram Ti; lines 4–6 make the upper trigram Yong and the lower trigram Ti. Do not default to lower=Ti.

Claim source: received Meihua Yishu, vol. 2, “General Instructions for Ti and Yong,” for the body/function frame and principal/matter distinction. In this course's single-moving-line convention, the moving trigram is Yong and the unchanged trigram is Ti; the line-position rule above makes that assignment reproducible.

Five Phase Direction

The direction matters.

RelationBetter wording
Yong generates TiThe active matter supports the body or subject.
Ti generates YongThe body or subject feeds the active matter, with possible cost.
Yong controls TiThe active matter pressures or restricts the body or subject.
Ti controls YongThe body or subject can manage or contain the active matter.
Same phaseShared nature, reinforcement, rivalry, or excess.

This avoids the common mistake of calling generation always good and control always bad.

Example: Wood generating Fire can mean growth and expression. But if Wood is the body and Fire is the function, Wood is also being consumed to produce Fire. The reading may be productive and draining at the same time.

These are symbolic lineage relations, not physical causes or guarantees.

Claim source: received Meihua Yishu, vol. 1, “Five Phases Generate and Control” and “Eight Palaces' Five-Phase Associations”; Sun's modern presentation, pp. 44–45, provides a later example of the mapping but is not used as evidence of efficacy.

Time and Season

If a named lineage supplies a precise seasonal rule, record that rule and source before applying it. This course does not teach a seasonal strength algorithm. Do not import WWG line-state analysis into the reading.

Primary, Line, and Changed Hexagram

Read the result in three movements:

LayerFunction
Primary hexagramThe present moment-image.
Moving lineThe pressure point where the image turns.
Changed hexagramThe structural result of changing the selected line; this course reads it as a possible direction, not a guaranteed future.

The changed hexagram is the deterministic state produced by the moving line. UAYA reads it together with Ti/Yong and the Five Phase relation as one possible development. That reading is interpretation, not another construction fact.

Course Case

Example type: invented teaching case. It has no reported outcome and is not evidence of predictive efficacy.

Question: “Does this workshop proposal have life in it?”

Calculation result:

  • Primary hexagram: Fire over Heaven, Hexagram 14, Great Possession.
  • Moving line: line 2.
  • Changed hexagram: Fire over Fire, Hexagram 30, Clarity.

Interpretive table:

LayerReading
ObservationLi is above Qian; line 2 moves in the lower trigram; the result is Hexagram 30.
TiUnchanged upper Li, Fire: the subject in this course reading.
YongChanging lower Qian, Metal: the function or delivery vehicle.
Lineage relationTi Fire controls Yong Metal.
Received textHexagram 14, line 2, includes a large-wagon/carrying image; Hexagram 30 concerns Li, attachment/brightness.
UAYA synthesisThe visible idea may be able to discipline its vehicle, but control can require effort or become rigid.

Practical reading:

The selected moment presents a visible idea in tension with its delivery vehicle. The proposal may be able to discipline that structure, but doing so will require attention and could become rigid. Clarify the audience, schedule, promise, and delivery format before deciding; confidence is medium.

Write the Reading in Three Sentences

Use this format:

  1. Moment image: What the primary hexagram shows.
  2. Pressure point: What the moving line and Ti/Yong relation show.
  3. Practical guidance: What to do next.

For the case:

The moment shows a visible idea above a strong vehicle. The moving lower trigram makes that vehicle the active matter, while Ti Fire controlling Yong Metal suggests manageable but effortful tension. Clarify the delivery structure before increasing promotion; confidence is medium.

Plausible alternative: Fire controlling Metal can also describe presentation requirements constraining an otherwise strong proposal. Because both readings fit the same symbols, later evidence must decide between them; the cast alone does not.

Text source: received Yijing, Hexagram 14, line 2, and Hexagram 30. The table and three-sentence reading are UAYA synthesis. The construction 14.2 → 30 is verified independently from the line change.

Interpretation Traps

Trap Only reading hexagram names

Names are useful, but the method needs trigram relation, moving line, and context.

Trap Turning phases into moral labels

Generation can drain. Control can protect. Same phase can support or compete.

Trap Overpromising prediction

Plum Blossom shows a moment-image. It does not remove uncertainty or responsibility.

Stop when the recorded layers support no coherent bounded statement, when two alternatives remain equally plausible, or when the question requires medical, mental-health, legal, financial, safety, or emergency judgment. Use inconclusive and the appropriate professional support rather than increasing certainty.

Practice Standard

For each reading, keep a short case note:

  • Input cue.
  • Calculation.
  • Ti/Yong assignment.
  • Five Phase relation.
  • Primary, moving-line, and changed-hexagram synthesis.
  • Three-sentence reading.
  • Confidence: high only for arithmetic, lower for interpretation.
  • Plausible alternative or inconclusive decision.
  • Follow-up result.
  • What you would change next time.

Review both apparent hits and misses. Do not revise the original notes after the outcome is known.
