Western feng shui talks about the human psyche part of intention as well as color, design, aromatherapy and that type of thing. For instance, what color to paint your house. Or, for example, if you put two flowers in your marriage corner, then what will manifest is an enhanced relationship. On the other hand, the practice of authentic feng shui deals with your environment and the chi, or energies, that's in it. We use a Chinese compass called a Luo Pan compass.
Most masters make their own.
It's an ancient compass that consists of a square base, and within that square base are seven to 36 different rings. Each ring has a different formula. You use the compass to take measurements of the incoming chi of your environment. For example, certain roadways are in front of your house, or perhaps a river. We take measurements of what direction these are coming from as well as other surroundings such as mountains or hills or buildings.
