Learn to tell your own fortune, okay?

Is it harmful to learn fortune-telling knowledge and help others fortune-telling? It is said that fortune-telling will be punished if it doesn't follow the laws of nature. Is it true?/You don't say.

Fortune tellers don't harm people, but point out mazes and the like. It's actually just a cover. The person who swindled money with this clearly didn't hit others, which made people panic. You should pay him to help you eliminate the disaster. Fortune telling is a mysterious subject related to heaven, earth and five elements. The subject itself does not harm people, just like a knife. The knife itself is harmless, but people use it to do bad things.
