How to find the Sword Edge Metal
The Na Yin pair up the sixty stem-branch pillars into thirty names; 壬申 and 癸酉 share Sword Edge Metal. The Na Yin of the year pillar is often called one's life Na Yin, so people with a 壬申 or 癸酉 year pillar are said to have a Sword Edge Metal life. BaZi years change at Lichun (around 4 February), so anyone born in January or early February uses the previous year's pillar.
| Pillar | Years (1900–2099) |
|---|---|
| 壬申 | 1932, 1992, 2052 |
| 癸酉 | 1933, 1993, 2053 |
The image and meaning of Sword Edge Metal
Sword Edge Metal is a honed blade: sharp, decisive and strong. Traditionally it describes determined, straightforward people with nerve and a sense of justice.
A sword is made by fire and quenched in water, so this Na Yin is often read as growing sharper through hardship; but an edge that shows too much can cut others, so it must learn when to hold back.
How to read it in a chart
- Year pillar
- the year pillar's Na Yin is the “life” Na Yin, traditionally used for a person's general temperament and, in compatibility matching, for comparing two people's Na Yin.
- Day pillar
- the day pillar's Na Yin is seen as closer to the self; some schools use it to add detail on temperament.
- Other pillars
- the Na Yin of the month and hour pillars, luck pillars and years are usually read only as background, not as good or bad on their own.
Sword Edge Metal and the regular Five Phases
- Na Yin element
- Sword Edge Metal's Na Yin element is Metal, taken from the 壬申–癸酉 pair as a whole.
- 壬申 (Ren Shen)
- the stem 壬 is Water, the branch 申 is Metal.
- 癸酉 (Gui You)
- the stem 癸 is Water, the branch 酉 is Metal.
Common misconceptions
- Na Yin cannot decide good or bad fortune on its own. BaZi analysis rests on the regular Five Phases and the Ten Gods; Na Yin is a supporting symbol.
- A Sword Edge Metal life refers to the year pillar's Na Yin only; it does not make the whole chart Metal.
- Clashing Na Yin in compatibility matching does not mean a poor match; modern readings weigh how the two whole charts fit together.
Frequently asked questions
Do I have a Sword Edge Metal life?
Look at your year pillar: if it is 壬申 or 癸酉, yes. You can use the years in the table, but if your birthday is before Lichun (around 4 February), use the previous year. The surest way is to check the year pillar's Na Yin in the free calculator.
Is Sword Edge Metal's element just Metal?
Its Na Yin element is Metal, which is not the same as the regular Five Phases used in BaZi. Judging the Day Master's strength and useful god uses the regular elements of the stems and branches, not the Na Yin.
How important is Na Yin in BaZi?
Na Yin is an older supporting system, used for the “life” element of the year and in traditional compatibility matching. Modern BaZi analysis rests on the regular Five Phases, the Ten Gods and the chart's structure, so Na Yin is best read as a symbolic reference.
