Na Jia
Na Jia assigns earthly branches and five phases to each line. Without it, a line is only yin or yang; with it, the chart can speak in terms of month, day, clash, combination, and Six Relatives.
Classical Sources
The classical passages below are kept short. The point is not to copy old manuals, but to show how a rule enters an actual Liuyao chart.
Zengshan Buyi
“乾在内卦，子水寅木辰土。”
Read Na Jia after the hexagram is formed and before choosing the useful line. The palace gives the reference phase; Na Jia gives the phase of each line. Their relationship produces the Six Relatives.
How It Works In A Chart
| Role | How to read it |
|---|---|
| Inner Qian | zi-water, yin-wood, chen-earth |
| Outer Qian | wu-fire, shen-metal, xu-earth |
| Main use | gives each line a branch and phase |
Chart Layer Example
A Liuyao line is read through several layers at once. This small sketch is not a full chart, but it shows why a term cannot be judged as a loose word.
| Layer | What to check | Why it matters |
|---|---|---|
| Line position | first through sixth line | position gives near or far, early or late, inner or outer clues |
| Na Jia branch | Zi, Chou, Yin and the other branches | branch decides phase, clash, void, and possible timing |
| Six Relative | Parents, Brothers, Children, Wealth, Officer/Ghost | this tells what the line represents in the question |
| Shi-Ying | self side and responding side | this shows whether the matter reaches the asker or stays outside |
| Month and day | support, clash, void, break | this tells whether the sign has power now |
| Movement | moving line and changed line | this shows where the chart is changing |
Reading Sequence
A useful habit is to separate role, strength, and action. Role tells what the line represents. Strength tells whether it can act. Action tells whether it helps, harms, hides, or delays the matter.
- State the question in one sentence.
- Cast and set up the chart before choosing meanings.
- Choose the useful line from the question type.
- Check Shi and Ying so the reading has a self side and an outside side.
- Judge month, day, void, break, and moving lines only after the structure is clear.
Reading Notes
Read Na Jia after the hexagram is formed and before choosing the useful line. The palace gives the reference phase; Na Jia gives the phase of each line. Their relationship produces the Six Relatives.
Common Mistakes
The usual error is to memorize a relative name without knowing the branch behind it. If inner and outer trigrams are reversed, every later judgment shifts.
Small Example
For a simple reading, identify whether Na Jia affects the useful line or Shi. If it does not touch the main question, keep it as background.
FAQ
What is Na Jia in Liuyao?
Na Jia is a specific layer of the Six Lines chart. It should be read inside the full structure of palace, Six Relatives, Shi-Ying, month, day, and moving lines.
When should I read Na Jia?
Read it after the chart is properly cast. It is useful only when the question, useful line, and time forces are already clear.
Does Na Jia decide good or bad by itself?
No. It gives important information, but Liuyao judgment depends on how that information acts on the useful line and on Shi.
What is the common beginner mistake?
The usual error is to memorize a relative name without knowing the branch behind it. If inner and outer trigrams are reversed, every later judgment shifts.
Which pages should I read next?
Read the terms index, Yong Shen, and Month And Day together. They keep the judgment from becoming a single-label answer.
