Orienting the feng shui bagua map is really easy, you just need to follow some simple feng shui rules. Usually you align the bagua diagram with the front door. The front door is the mouth of chi—it's where all the energy enters into your home. However, if your front door is blocked or NEVER used, then align the feng shui bagua map with the most commonly used door.
To align the bagua map, imagine you are looking down on your house from a birds-eye view and then place the map over your house. The front door of your house should align with the bottom of the bagua map.
You can stretch and squeeze the shape of the bagua diagram so that the majority of your home fits inside the bagua map. Ideally, you have a square or rectangle home that fills every part of the bagua diagram like the examples below.
However, many times that is not the case due to an asymmetrical layout which means there will be a missing area or extension. The general rule of thumb is that a part of the bagua is missing if the negative space is less than half the size of the side. See the examples below.
Feng shui cures are an excellent way to "fill in " the missing areas of the feng shui bagua map.
Extensions, on the other hand, can be very beneficial. If you move into a home with an extension in the abundance area, you may find that you experience greater prosperity and financial wealth.
The feng shui bagua diagram is oriented the same for all floors. And remember, you can also apply the feng shui bagua to each individual room—just align the bagua with the door entering into the room.
