As incredible as it may sound, the shape of your residence and the location of the room that you are at influence your personality, your looks and even your sex life. All is explained in the BaGua, the arrangement of eight (Ba) trigrams (Gua) that results from the interaction of yin and yang and represents everything that exists, including you.
The BaGua is a mathematical model to calculate Qi, if you understand the BaGua you are able to deduce what happens in a property. The first step to do that is to superimpose the BaGua on the property, the second step is to calculate the Gua of the occupant(s) and the third step is to know the characteristics of each Gua and apply them accordingly.
To superimpose the BaGua on your property, lay over its floor plan a 3 x 3 grid to obtain eight equally sized boxes on the sides and one in the center. Label each box on the sides with a cardinal or ordinal compass direction: go to the center of the property, hold the compass in your hands pointing towards any direction, stay still until the compass stops moving, mark that direction on the corresponding box and then label the other seven boxes accordingly. Each box is considered a sector and houses a Gua.
To calculate your Gua (Life Star) go to my BaZi Calculator, input your date of birth (no need to input your time of birth) and plot your BaZi chart. Your Gua comes out under your name, on the top right side of the page. Males identified with Gua 5 are treated as Gua 2. Females identified with Gua 5 are treated as Gua 8.
The characteristics of each Gua are endless. Table 1 shows some basic ones, which are very easy to apply.
