People who follow this religion believe that doing something with words, thoughts, symbolic actions, etc. can make things in the real world change. That idea is hard to understand. Here is an example: There is an old story that says China was once covered by a flood. The world was saved from the flood by 禹 Yǔ, who had only one leg that worked. Yǔ went to different parts of China in a special order, and he dug ditches to let the flood water go into the ocean. When something very bad happens in the world, a Daoist priest can go to the Daoist temple and act out what Yǔ did, and just doing that will make the world get fixed.
