Core Question in Six Lines:Daily Clash on a Static Line Hidden Movement or Daily Break?
The Daily Ruler is the trickiest part of Six Lines. Let’s clarify hidden movement, daily break, and key day–month differences simply.
Strength & Weakness by the Daily Ruler: Three Basic States
On the level of fortune judgment, the Daily Ruler influences lines similarly to the Monthly Ruler, dividing them into Prosperous, Neutral, and Weak.
I. Prosperous by the Daily Ruler
Line matches the Daily Ruler (Lin Ri Jian)
Static line combines with the Daily Ruler (Ri He)
Line is generated by the Daily Ruler
Line is supported by the Daily Ruler (same element)
Line is at Longevity or Imperial Prosperity under the Daily Ruler
II. Neutral by the Daily Ruler
Line overcomes the Daily Ruler
Line generates the Daily RulerNeither side is harmed; the line remains neither strong nor weak.
III. Weak by the Daily Ruler
Line is overcome by the Daily Ruler
Line is at the Jue (Dead-End) position under the Daily Ruler
Strength Hierarchy
Higher prosperity: Lin Ri Jian, static line in Ri He
Ordinary prosperity: other prosperous conditions
Ordinary weakness: overcome by day, or at Jue position
Longevity, Imperial Prosperity, Tomb, and Jue
The theory of Sheng Wang Mu Jue (Birth, Prosperity, Tomb, Dead-End) is unique to the Daily Ruler — the Monthly Ruler does not use it.
Core Rule:
A prosperous line follows prosperity; a weak line follows weakness.
Prosperous line + Daily Longevity / Imperial Prosperity = becomes even stronger
Weak line + Daily Longevity position = not counted as Longevity, only neutral
Essential Difference: Monthly Ruler vs. Daily Ruler
Monthly Ruler: has Xiu Qiu (Decline). Line generating or overcoming the month = weak.
Daily Ruler: no Xiu Qiu. Line generating or overcoming the day = neutral.
Four Similarities & Four Differences
Similarities
Equal statusMonth and day jointly form the external environment; they are said to be “equally powerful.”
Matching the ruler equals breaking the rulerLin Yue Jian / Lin Ri Jian is parallel to Yue Po (Monthly Break) in influence level.
Same generating & overcoming logicBoth support, generate, and overcome lines by the same rules.
Same rules for moving lines meeting or breaking against sun/moon
Differences
Daily can stimulate static lines; Month cannotMonth clashing line = Yue Po (absolute weakness)Day clashing line = either Hidden Movement or Daily Break
Sheng Wang Mu Jue exists only for the Daily RulerMonth only uses Wang Xiang Xiu Qiu; no “Monthly Tomb.”
Combining rules differ
Month He: both moving & static lines become prosperous
Day He: static line prospers; moving line is Ri Ban (Bound by Day)
Xiu Qiu exists only for the Monthly Ruler
Static Line vs. Moving Line in Daily Combination
Static Line + Day He = Prosperous
The line is strengthened, counted as a higher-level prosperity.
Moving Line + Day He = Ri Ban (Bound)
The line is restrained and cannot act freely.
Mnemonic
Month He makes all lines prosper, moving or still. Day He prospers the still, but binds the moving still.
Common mistake: believing “Month Ban” exists. Yue He only strengthens; it never binds.
Daily Clash on Static Line:
Hidden Movement vs. Daily Break
Month clashing any line = Yue Po (broken).Day clashing a static line has two outcomes, based on the line’s strength.
- Prosperous static line + Day Clash = Hidden Movement (An Dong)
The line is roused into effective short-term action. It acts like a useful moving line.
- Weak static line + Day Clash = Daily Break (Ri Po)
The line is scattered and weakened, becoming ineffective.
Ancient Teaching (from Zeng Shan Bu Yi)
A prosperous static line, when clashed by day, becomes hidden movement and gains power.A weak static line, when clashed by day, becomes daily break and is useless.
Moving Clash vs. Transforming Clash
Moving Clash (Moving Line Clashed by Day)
Also called Dong San (Scattered Movement).But any moving line clashed by day remains effective, regardless of strength.
Prosperous moving line + Day Clash = greatly strengthened
Weak moving line + Day Clash = still effective, though initially difficult
Transforming Clash (Changed Line Clashed by Day)
Depends on timing:
Short-term question:Changed line prosperous under month + Day Clash = Hidden MovementChanged line weak under month + Day Clash = Scattered
Long-term question:All transformed clashes count as Scattered, never Hidden Movement.
Why?Day clash carries a short-term nature. It cannot sustain long-term power.
Three Kinds of False Scattering
Not all transformed scattering is real:
Moving line transforms to turn back and act
Moving line advances strongly
Self-line transforming to scatter in self-divination
Deep Meaning of “Sun and Moon Equal in Power”
This ancient saying only applies to fortune judgment.
On the Fortune Level:
Sun and moon are equally powerful, jointly deciding prosperity or weakness.A line broken by month can still be strong if supported by day.
On the Timing (Ying Qi) Level:
Monthly power > Daily powerMonth rules the month; day supports but does not dominate.
Time Effects of the Daily Ruler
Short-term questions
Daily power dominates within the day.Results often occur the same day or next.
Long-term questions
Daily power works across months but never surpasses monthly dominance.
Detailed Meaning:
Month rules the past; Day rules the present.
Lin Ri Jian = current situation
Ri Po = current ineffectiveness or unfulfilled state
Core Summary Mnemonic
Month governs Wang Xiang Xiu Qiu;Day governs Sheng Wang Mu Jue. Still lines combine to prosper;Moving lines combine to bind. Day clash makes hidden movement or break,Judged solely by the line’s strength.
Key Pitfalls to Avoid
No such thing as “Month Binding” only Day Binding exists
Daily Longevity only applies if the line is already strong
Long-term questions: transforming clash = always scattered
Timing level: Month > Day; they are NOT equal
