Na Yin: a poetic name for each pillar
Long ago, Chinese scholars gave each of the sixty pillars a short poetic name, almost like a nickname: "Metal in the sea", "Willow wood", "Lamp fire". These names are the Na Yin (納音).
The words mean roughly "the sound it takes in". The old books tied them to musical notes, and the name stuck.
Thirty names for sixty pillars
The sixty pillars go two by two, and each pair shares one name. 甲子 and 乙丑 are both Metal in the sea. 丙寅 and 丁卯 are both Furnace fire. That makes thirty names in all.
An element of its own
Each Na Yin has its own element, and it's often not the element of the stem or the branch. 甲子 has Wood on top and Water below, yet its Na Yin is Metal: Metal in the sea.
Think of it as a second, poetic reading of the same pillar. It doesn't correct the first one.
What it says, and what it doesn't
The tradition reads the picture in the name:
- Metal in the sea: hidden treasure, talents that show over time.
- Willow wood: flexibility and grace.
- Pine and cypress: endurance and a long life.
- Stream water: clarity and steadiness that carve a path.
- Lamp fire: guidance and clarity in the dark.
- Roadside earth: useful simplicity that clears the way for others.
It's an image, not a measure of strength. The app doesn't use Na Yin to count your elements or to rate your years. Those come from the stems, the branches and the hidden stems.
Where to see it
On the Chart tab, open Symbols. "Na Yin of your pillars" shows the name of each of your four pillars, with its characters. The Life palace and the Conception palace on the same screen show theirs too.
In the full reading, the "Palaces, Na Yin and stars" section has a short line for each pillar.
A nice way to use it
Read the four names out loud and see which picture feels like you. Someone with Pine and cypress in the Day pillar might smile at it after a hard winter. If a name doesn't fit, let it go. It's poetry from the tradition, not a verdict.
