Detailed Guide to Six Lines World-Response Calculation

I. Theoretical Foundation of the Eight Palace Hexagram Transformation System

1.1 Overview of the Eight Palace System

The sixty-four hexagrams are classified into eight palaces, each headed by one pure hexagram and containing 8 hexagrams:

Qian Palace: Headed by Qian for Heaven
Kan Palace: Headed by Kan for Water
Gen Palace: Headed by Gen for Mountain
Zhen Palace: Headed by Zhen for Thunder
Xun Palace: Headed by Xun for Wind
Li Palace: Headed by Li for Fire
Kun Palace: Headed by Kun for Earth
Dui Palace: Headed by Dui for Lake

1.2 Palace Internal Hexagram Sequence Arrangement Rules

The arrangement of 8 hexagrams within each palace follows fixed patterns:

Eight Pure Hexagram (Palace Hexagram): World line at 6th line - Base hexagram, no change
First World Hexagram: World line at 1st line - Palace hexagram changes first line
Second World Hexagram: World line at 2nd line - First world hexagram changes second line
Third World Hexagram: World line at 3rd line - Second world hexagram changes third line
Fourth World Hexagram: World line at 4th line - Third world hexagram changes fourth line
Fifth World Hexagram: World line at 5th line - Fourth world hexagram changes fifth line
Wandering Soul Hexagram: World line at 4th line - Fifth world hexagram changes fourth line
Returning Soul Hexagram: World line at 3rd line - Wandering soul hexagram changes lower three lines simultaneously

II. World-Response Position Determination Rules

2.1 World Line Determination Rules

The World line position is completely determined by the hexagram's sequence number within its palace:

Eight Pure Hexagram: World at 6th line (top line)
First World Hexagram: World at 1st line (bottom line)
Second World Hexagram: World at 2nd line
Third World Hexagram: World at 3rd line
Fourth World Hexagram: World at 4th line
Fifth World Hexagram: World at 5th line
Wandering Soul Hexagram: World at 4th line
Returning Soul Hexagram: World at 3rd line

2.2 Response Line Determination Rules

The position relationship between Response and World lines is fixed, separated by two line positions:

1st line corresponds to 4th line
2nd line corresponds to 5th line
3rd line corresponds to 6th line
4th line corresponds to 1st line
5th line corresponds to 2nd line
6th line corresponds to 3rd line

Memory Formula:

First world fourth response, second world fifth response, third world sixth response,
Fourth world first response, fifth world second response, sixth world third response.

IV. Practical Calculation Techniques

4.1 Quick Palace Identification Methods

Look at the Upper Trigram (Outer Trigram):

Qian Palace hexagrams: Outer trigram mainly Qian, heaven symbols
Kan Palace hexagrams: Outer trigram mainly Kan, water symbols
Gen Palace hexagrams: Outer trigram mainly Gen, mountain symbols
Zhen Palace hexagrams: Outer trigram mainly Zhen, thunder symbols
Xun Palace hexagrams: Outer trigram mainly Xun, wind symbols
Li Palace hexagrams: Outer trigram mainly Li, fire symbols
Kun Palace hexagrams: Outer trigram mainly Kun, earth symbols
Dui Palace hexagrams: Outer trigram mainly Dui, lake symbols

Special Cases: The outer trigrams of Wandering Soul and Returning Soul hexagrams may differ from their palace trigram symbols; palace affiliation must be determined through the inner trigram.

4.2 Memory Formula Summary

World Line Position Formula:

The first of eight trigrams has world at six,
One, two, three, four, five ascend in fix.
Wandering soul at four, returning soul at three,
This method eternal, never changed shall be.

Response Line Position Formula:

World and response separated by two line positions,
First-fourth, second-fifth, third-sixth compositions.
Fourth-first, fifth-second, sixth-third pairs,
Mutual correspondence never despairs.

4.3 Quick Verification Method

After obtaining a hexagram, follow these steps to verify World-Response:

Determine Palace: Judge which palace it belongs to based on hexagram name or symbol
Determine Hexagram Type: Which position (1-8) within that palace
Determine World Line: Directly correspond to world line position based on hexagram type
Determine Response Line: Calculate response line position based on world line position
Cross Verification: Compare with complete reference table for confirmation

V. Common Errors and Precautions

5.1 Common Calculation Errors

Palace Affiliation Confusion: Especially with Wandering Soul and Returning Soul hexagrams, easily calculating by wrong palace
World-Response Position Reversal: Remember it's "World-Response" not "Response-World" order
Line Position Numbering Errors: Must follow first line=1, second line=2...top line=6 sequence
Wandering Soul Returning Soul Specificity: Wandering Soul hexagram world at fourth line, Returning Soul hexagram world at third line, cannot follow regular ascending pattern

5.2 Learning Suggestions

Memorize Eight Palace Lead Hexagrams: The eight pure hexagrams must be thoroughly mastered
Understand Transformation Patterns: Grasp the internal logic of hexagram changes, not mechanical memorization
Practice Application More: Form conditioned reflexes through extensive practice
Establish Verification Mechanism: Cultivate cross-verification habits

VI. Conclusion

The calculation of Six Lines World-Response appears complex but actually follows patterns. The key lies in understanding the internal logic of Eight Palace hexagram transformations and grasping the fixed relationships of World-Response positions. Skillful application of this method is the foundation for accurate Six Lines divination.

Remember: World line for self, Response line for the divined. World-Response strength determines fortune.

This calculation method has been verified by generations of Yi learning scholars and is accurate and reliable. After mastering it, one can quickly and accurately determine the World-Response positions of any hexagram, laying a solid foundation for subsequent hexagram analysis.
