The principle of Feng Shui is based on the mutual generation and restraint of the Five Elements. These five elements (energy) constrain and promote each other, forming a dynamic balance system. Understanding Feng Shui requires a relativity concept, and these five elements can be applied to the movement of celestial bodies in the universe, the internal organs of animals, seasons, colors, tastes and other fields.
For example, it is best not to place metal objects in the center of the house, because earth produces metal, so earth is the mother of metal, and metal also reduces the power of earth. Earth belongs to the spleen and stomach in the five organs and six organs, so placing a relatively large metal object in the center of the house is not good for the owner’s spleen and stomach.
