The Non-Divination Rules
Last updated 5/21/2026
Not every question deserves a cast.
That is not a modern safety add-on. It is part of the classical operating logic. Wen Wang Gua assumes a real question, a sincere intention, and a matter that can be represented by a target line. If the question is fake, scattered, repeated, delegated without the person’s focused concern, or too vague to resolve, the problem is not that the method is weak. The problem is that the input is broken.
A note about the count
You will often see this topic called “the Six Non-Divinations.” It is a useful label, but it is not a neat numbered list handed down as six bullets in the main source. Yehe’s text gives a series of operating principles and case demonstrations: sincerity, one intention, self-divination, avoiding frivolity, avoiding repeated casts, and so on.
This course uses “non-divination rules” as a practical umbrella. The exact count matters less than the discipline: some questions should be refused or repaired before a cast happens.
Curiosity, performance, testing, and "let's see what happens" do not produce clean readings.
A single cast cannot carry three different worries and still be expected to answer clearly.
Proxy casting fails when the person whose matter is being asked about is not actually focused on the question.
Source basis: Zengshan Buyi operating-principles and sincerity/preconditions passages. The course translates the doctrine into English working rules rather than asking learners to parse the source formulas first.
The mixed-up reading, operationally
We met the mixed-up reading in the lineage module. Here it becomes a practice rule.
A young man and an elder arrive together. The young man intends to ask about career; the elder wants to ask about a sick son. The elder casts first, but the chart answers the young man’s unspoken career question. Then the young man casts, and the chart answers the elder’s sick-son question.
Yehe’s conclusion is practical: the oracle responds to the sincere intention that is actually present, not merely to the ritual order.
That gives us three intake rules:
Whose concern is actually active? If that person is absent from the question, be careful.
Do not cast while holding several desired answers in the same question.
If the answer would not change attention, action, or understanding, the cast is probably frivolous.
Failure modes
The question is a challenge, joke, or demonstration rather than a real concern.
The answer would not matter to the person asking.
The cast may answer one hidden question, another hidden question, or nothing usable.
Someone asks on behalf of another person without that person's real intention present.
"Will my life be good?" is too broad for one cast. Split or route the question.
The asker recasts because they disliked the first answer. That is not confirmation; it is evasion.
The answer-shopping trap
The most common modern abuse is simple: cast, dislike the result, cast again, dislike that result, cast again until something favorable appears.
That violates the core premise. If the first sincere cast answers the question, then a recast made only to overrule that answer is no longer the same question asked sincerely. It is an attempt to negotiate with the method.
A new cast is justified only when the matter has materially changed: a new offer, diagnosis, deadline, person, document, risk, or decision point. A changed mood is not enough. “I want a better answer” is not enough.
The asker accepts that the chart may be favorable, unfavorable, delayed, or unclear.
The asker is no longer seeking information. They are seeking permission.
We return to this in Act 10 when we build the operational refusal flow and refuted-doctrine registry.
Seek the good, avoid the bad
The philosophy behind the refusal rules is agency, not fatalism.
The classical practice phrase is often translated as “seek the good and avoid the bad.” The point is that a reading should help someone act more wisely. A refused reading can serve that goal just as much as a delivered reading. If the question is malformed, saying “not this question, not like this” protects the person and the method.
Real stake, one intention, proper ownership, specific enough to resolve.
Split broad questions, clarify domains, or identify the actual target before casting.
Testing, answer shopping, unsafe framing, or delegated concern without real ownership.
Refusal does not close the door. It asks for a better question.
Where this lands us
We now know that a cast has preconditions. The next question is smaller and more visual: once a proper question has produced a cast, can we read the table in front of us?
