Vernacular translation: The better the music, the lower it is, and the better the image. Metaphor "the greater the achievement, the more penetrating, more tolerant and more tolerant."
Listen to thunder in silence; See prosperity in a colorless place.
Explanation: listen to thunder in a quiet place; Look at the prosperity of the world in a sparsely populated place.
Summary: Silent and colorless refers to an extremely dull environment, things or people. Thunder and prosperity are both beautiful in melody, which means that you can feel extraordinary things from the most ordinary and common places, which requires a high level. The so-called "loud voice" and "elephant" of Laozi and Zhuangzi are intangible.
