Scope, Later Applications, and Boundaries
Last updated 10/7/2026
Eight Palaces is a precise way to classify the sixty-four hexagrams. That precision does not make it a universal theory of spaces, bodies, minds, or organizations.
Your task in this lesson is to audit an application claim before using or repeating it. The governing rule is simple: shared vocabulary is not evidence of a shared mechanism.
The five destinations for a claim
Route each claim according to the evidence it actually has.
| Destination | Use it when | Required record |
|---|---|---|
| Keep as structure | The claim is directly reproducible from the palace tables or line-change rule. | Show the reader-facing calculation or table. |
| Attribute as lineage | A named later school or author teaches the application. | Name the lineage and cite a checkable passage. Do not call it universal. |
| Route elsewhere | The claim belongs to another UAYA method or reference page. | Link to the page that owns the method. |
| Route out of the course | The claim concerns health, mental health, law, finance, safety, death, or a concrete outcome. | Do not use the palace table to guide the decision; direct the person to an appropriate qualified professional. |
| Cut | The claim has no adequate source, turns analogy into causation, or exceeds UAYA’s authority. | Record why it was rejected. |
This is a UAYA teaching tool, not a classical taxonomy. It keeps structural observation separate from later interpretation.
Four worked audits
1. A trigram direction
“The received Shuo Gua associates Qian with the northwest.”
Route: keep as a sourced textual correspondence. The direction appears in the received text’s directional sequence. The claim should point to the Shuo Gua, chapter 5, permanent revision 2614055.
What does not follow is a remedy. The textual correspondence alone does not establish that placing Metal objects in a northwest room will change authority, luck, or another outcome.
2. A later spatial practice
“A named Feng Shui school assigns a remedy to a sector because of a trigram correspondence.”
Route: attribute as lineage or route elsewhere. To retain the statement, the writer needs the school’s name, the exact rule, and a checkable source. Eight Palaces does not supply that rule merely because both systems mention trigrams or directions.
This course does not teach sector remedies.
3. A body image
“The Shuo Gua lists a body image for a trigram; therefore a palace member diagnoses disease in that body area.”
Route: cut. The body-image list in Shuo Gua, chapter 9 is textual evidence for a correspondence. It is not evidence of medical causation, diagnosis, prognosis, or treatment.
The source layer is real. The clinical conclusion is not established by it.
4. A business analogy
“A team can use palace order as an invented workshop analogy for checking whether a process description skipped a step.”
Route: keep only as a labelled analogy. The exercise may help participants inspect a sequence, but it does not forecast a company’s stage, risk, sales, or timing. The palace order remains the source mechanism; the organizational example is UAYA’s constructed comparison.
Claim-routing exercise
Classify each statement before looking at the answer key.
- “Hexagram 35 is the Wandering Soul member of the Qian family.”
- “Wandering Soul always means that a real situation is entering crisis.”
- “Chapter 11 of the Shuo Gua contains extended trigram images.”
- “A trigram body image proves that its palace governs an organ.”
- “This named later lineage uses palace membership in a separate method; its exact source is attached.”
- “Because an office case improved after a remedy, the Eight Palaces mechanism is validated.”
Answer key
| Statement | Route | Reason |
|---|---|---|
| 1 | Keep as structure | It is checkable in the received Qian catalogue and the verified palace sequence. |
| 2 | Cut | A structural label does not establish a universal event or emotional state. |
| 3 | Keep as sourced text | The statement is bounded to what the cited text visibly contains. |
| 4 | Cut | It converts correspondence into medical causation. |
| 5 | Attribute as lineage | The attribution and locator keep a later use from becoming universal history. |
| 6 | Cut | An outcome story without controlled evidence does not validate a mechanism. |
The stop rule
When a claim moves from an observable table into a life outcome, ask four questions:
- What changed: the evidence, or only the language?
- Which source supports the new step?
- Is the source describing a received text, a later lineage, or an invented analogy?
- Does the claim enter a high-stakes domain?
If the new step has no defensible source, stop. Do not preserve it by making it sound gentler.
You now have the boundary tool needed for the capstone. Continue to Capstone: Construction, Sources, and Error Review and apply this routing method to a complete course record.
Source note
- Yi Zhuan, “Shuo Gua” (說卦), permanent Wikisource revision 2614055, especially chapters 5, 9, and 11. The cited text supports the correspondence examples only; it does not establish remedies, diagnosis, or causal effects.
