On the Dayan Yarrow Stalk Method
Exploring the philosophical significance and operational principles of the Great Expansion divination method from the I Ching
1. The Logic of Variations
In the three changes, the stalks removed (Suspended + Left Remainder + Right Remainder) follow specific patterns:
- 1st Change removal: 5 or 9
- 2nd Change removal: 4 or 8
- 3rd Change removal: 4 or 8
To get the final result, we look at the combinations of remaining stalks:
- To get Old Yang (9): One must have 36 stalks left. This means $49 - (5 + 4 + 4) = 36$.
- Condition: Each of the three changes must result in the minimum number of stalks being removed.
- To get Old Yin (6): One must have 24 stalks left. This means $49 - (9 + 8 + 8) = 24$.
- Condition: Each of the three changes must result in the maximum number of stalks being removed.
