The Short Answer: Kua 1 and the North
In feng shui, the number 1 most often means your personal kua number in the Eight Mansions system. Kua 1 is linked with the Kan trigram, the north, and the water element. Other meanings exist too, and the term can be used differently in different sources.
Three Meanings of “Number 1”
Feng shui writers use “number 1” in at least three ways:
- Your personal kua number. This is calculated from your birth year and gender. It is used to suggest personal favorable directions.
- The Lo Shu position. On the Lo Shu square, 1 sits in the north. This is a feature of the number system, not a personal number.
- A house or street number. Some tables assign meanings to house numbers, such as calling 1 “career.” These come from a different system and are not the kua.
Keep these apart. A table of house numbers should not be used to find your personal kua.
What Kua 1 Represents
Kua 1 is linked with water, the north, and the Kan trigram. Traditional teaching connects it with career, life path, and inner direction. Like other kua numbers, it is a symbolic framework for thinking about personal goals.
Kua 1’s Favorable and Unfavorable Directions
In the Eight Mansions reading for Kua 1, the directions are usually given as follows:
| Direction | Name in the system | Traditional reading |
|---|---|---|
| Southeast | Sheng Chi | Strongest good direction |
| East | Tian Yi | Good direction |
| South | Nien Yen | Good direction |
| North | Fu Wei | Good direction (wisdom) |
| West | Huo Hai | Unfavorable (mishaps) |
| Northeast | Wu Kuei | Unfavorable |
| Northwest | Liu Sha | Unfavorable |
| Southwest | Jue Ming | Most unfavorable |
These directions come from one school’s reading. Other schools use different charts, so check which one a guide follows before using it.
Activating the Water Element
For Kua 1, traditional guides suggest water and metal items to support the water element. A small fountain, a picture of water, or metal accents in the good directions are common examples. Traditional guides also advise against fire in the areas that support the water element.
Finding Your Own Kua Number
Your kua number is calculated from your birth year and gender. Different teachers use different formulas, and results can differ between them. Use a reputable calculator or a trained teacher, and check which method they use. This article does not give a formula, so you can verify the method yourself.
House Numbers
If a house number table calls number 1 “career,” treat that as a separate tradition. It does not tell you about your kua, and it does not tell you about the career area of your home. For the room-level career area, see the career area guide.
