The Five Phases: Generation and Control
Last updated 10/7/2026
Every branch in the chart carries one of five elements. This lesson adds two directional relations—generation and control—without deciding whether either relation is active or important in the reading.
Branch-to-element lookup
| Element | Branches |
|---|---|
| Water | Zi, Hai |
| Wood | Yin, Mao |
| Fire | Si, Wu |
| Earth | Chou, Chen, Wei, Xu |
| Metal | Shen, You |
The two directional cycles
Generation:
Water → Wood → Fire → Earth → Metal → Water
Control:
Wood → Earth → Water → Fire → Metal → Wood
Direction must be explicit. “Wood controls Earth” is not interchangeable with “Earth controls Wood.” When adding an arrow to a worksheet, write both the source and target.
Worked chart: Case 00035
Add the branch elements to Hexagram 3:
| Line | Branch | Element |
|---|---|---|
| 1 | Zi | Water |
| 2 | Yin | Wood |
| 3 | Chen | Earth |
| 4 | Shen | Metal |
| 5 | Xu | Earth |
| 6 | Zi | Water |
The chart visibly contains these possible phase directions:
- Water on lines 1 and 6 generates Wood on line 2.
- Wood on line 2 controls Earth on lines 3 and 5.
- Earth on lines 3 and 5 generates Metal on line 4.
- Metal on line 4 generates Water on lines 1 and 6.
That list is a relationship map, not a claim that every possible arrow is operating. Motion, target selection, calendar state, and the declared judgment order decide which relations are later evaluated.
Reproducible exercise
For each statement, mark generation, control, or neither:
| Direction | Result |
|---|---|
| Water → Wood | generation |
| Metal → Wood | control |
| Earth → Metal | generation |
| Fire → Water | neither; Water controls Fire in the reverse direction |
| Wood → Wood | same element, not generation or control |
Failure control: if reversing the arrow leaves your answer unchanged, you have replaced a directional operation with a vague association. Rewrite the relation as a sentence with a subject and object.
Boundary
Generation is not automatically favorable; control is not automatically unfavorable. Those are interpretive judgments that depend on which line is selected and what role each line plays. The Five Phases here are chart mechanics, not moral labels or physical causes.
Source note
The complete branch-element table and two directional cycles define the mapping used in this course. Write the direction explicitly before assigning a relationship.
Next: Continue to Branch Relationships and mark fixed branch-pair flags separately from the Five-Phase arrows.
