When heaven and earth are not divided, it is called a state of chaos. Heaven, earth, heaven and earth are mixed together, the sun, moon and stars have not been formed, day and night have not alternated between cold and heat, there are no wind, rain, thunder and lightning above, and there are no vegetation, mountains, rivers, people, birds, insects and beasts below. At this time, a spiritual energy was entangled and running inside, so water was born from Taiyi, fire was born from Taichu, wood was born from Taishi, gold was born from Taisu, and earth was born from Taiji. The five elements come from this. Since then, the world, vegetation, mountains, rivers, people, animals, insects, and animals have developed in their own way. Among them, there are many intelligent and spiritual people who have glimpsed its secrets and embarked on the path of cultivation.
