Some hexagrams carry a whole-chart atmosphere.

Six-Clash means the chart is structurally unstable and fast. Six-Harmony means the chart is structurally cohesive and slow to change.

Neither one is automatically good or bad.

Six-Clash Fast and unstable

Events move quickly, separate, break open, or resolve under pressure.

Six-Harmony Stable and persistent

Events bind, continue, settle, or resist quick change.

Speed is not direction

This is the key rule:

Six-Clash tells you pace, not outcome.

A Six-Clash illness reading can mean quick recovery or quick decline. A Six-Harmony marriage reading can mean stable union or persistent entanglement. The direction comes from the target line and its interactions.

Six-Clash Quick movement

Expect short timelines, disruption, release, or fast resolution.

Six-Harmony Persistence

Expect cohesion, delay, holding, continuation, or difficulty separating.

Target decides Good or bad depends on line condition

Read the target, support, obstacle, and timing before calling the result.

The closed list

The Six-Clash family is not something we extend by visual intuition. The source list is closed: the eight pure palace hexagrams, plus Hexagram 25 and Hexagram 34.

Palace primaries 1, 2, 29, 30, 51, 52, 57, 58

The eight pure-trigram hexagrams are Six-Clash.

Additional cases 25 and 34

Innocence and Great Power are also named in the source list.

Do not infer No analogy list

Popular split-trigram guesses can be wrong; use the chart header or the canonical list.

This matters because some popular materials classify by appearance and get the family wrong. In the source tradition we are following, the label is a technical chart type, not a mood.

Case 1

Case 1 begins with a Six-Clash hexagram. That tells us the father’s illness will resolve quickly one way or another.

It does not tell us whether he recovers.

The direction comes from the line mechanics: target strength, Dark Moving attack, support line, and the support chain blocked by combination.

Hexagram type Six-Clash

The case has a quick-resolution atmosphere.

Line mechanics Attack and blocked rescue

The target is under pressure and its rescue path is locked.

Timing Release decides

The outcome waits for the lock to break.

Common traps

Trap 1 Six-Clash equals bad.

It means unstable or fast. The result can still be favorable.

Trap 2 Six-Harmony equals good.

It means stable or bound. Stability can preserve a problem.

Trap 3 Letting the whole chart override the target.

The target line still decides the direction of judgment.

Source basis: Zengshan Buyi Six-Clash list and Six-Clash/Six-Harmony case tags. The Six-Clash set is the eight palace primaries plus Hexagrams 25 and 34; speed and durability are separate from outcome direction.

What this module establishes

Whole-hexagram types describe pace and persistence. They do not replace line analysis.
