Knowledge changes fate, and Buddhism enhances spiritual beauty, right?

In Buddhism's view, these two sentences are not valid. Knowledge can't change fate. I think it is fate that makes me study hard. Conversely, if I have knowledge, I will be sad and everything will go wrong. This sentence is just a slogan to encourage people.

Buddhism should have the function of purifying the soul and self-improvement, but what Buddhism wants is to get rid of pain and seek truth. If you learn from Buddha to make vases, increase blessings and show off yourself, it is tantamount to buying gifts and returning pearls. This is putting the cart before the horse. Of course, Buddha obeys all beings. Perhaps by blessing you and satisfying your wishes, you will have confidence in Buddhism, and you will not be accused, but this is not the basis for learning Buddhism.
