Are you referring to divination verses, for example?
The most common characteristic of them (note that I use "***tong" instead of "***tong") is arbitrariness. Say whatever comes to mind, there are few logically correct poems. The first sentence may be about the sky, and the next sentence may be about hell or the ocean. If you want to understand its meaning, you have to put your own emotions into it.
As for why this is so, it is because that is what the author of the prophetic poem saw, heard, and felt in the balanced space constructed (that is, where the things he wanted to know happened). One's deepest experience is the event that touches the most (this depends on the prophet's living environment. If he or she has never seen the world, he or she will have feelings about everything he or she sees). Then the recorder next to him or her will record what he or she said (sometimes the prophet will write down certain situations sporadically, but most of the time the prophet will not be able to remember the situation at all), and then follow the instructions. These are laid out using the template of poetry, which is the divination verse.
