What is the Theory of the five elements?
It is a theory in which everything in nature is considered to be formed by the 5 elements of "tree, fire, soil, metal, and water". They do not exist independently, but in balance with one another.
"Sosho" harmony and "Sokoku" discord
The 5 major elements are related to one another by either "Sosho", which nurtures and promotes the development of the counterpart, and "Sokoku", which restrains and hinders the development of the other. The 5 organs of humans apply to this. We can be healthy when Yin-Yang and the 5 elements are well balanced.
Tree generates fire - tree burns to make fire.
Tree cut through soil - tree penetrates into soil.
