How to invite good fortune and avoid misfortune is closely related to the environment surrounding one’s residence and personal life, such as health, wealth, marriage, career, progeny, etc. Therefore, the Feng Shui of a dwelling plays a very important role. How can we use the Feng Shui of our home to turn the tide in our favor? By leveraging the Xuan Kong Kan Yu Great Method's "Eye诀 Heart法" (Eye Secrets and Heart Methods) to examine the geomantic influences around the house, we can understand what constitutes negative energy (sha), how it arises, what unfavorable factors it may bring, and how it might affect us personally. Although Qi (energy) is invisible, its form can be observed. When the four elements—"form," "Qi," "time," and "space"—come together in harmony, it creates an auspicious alignment.
