Start with the structure
Eight Mansions (Ba Zhai) is the most accessible Feng Shui system. From your birth year and gender it derives your Gua (Kua) number, which splits the compass into four auspicious and four inauspicious directions that are personal to you.
Then read the interaction
You apply your directions by facing and placement — face your Sheng Qi for important work, sleep with your head toward a good direction, and site your desk and door where the personal energy supports you.
Put it to use
Because it needs only a birth year and a compass, Eight Mansions is the quickest win in Feng Shui — a daily alignment you can apply at your desk, your bed and your front door immediately.
