Why does chanting Buddha change fate?

Buddhist chanting is a kind of belief, which can also be said to be a kind of self-hypnosis. It means that you believe that no doubt is true and no doubt is false. If you have never doubted that Buddha can change your destiny, then you will subconsciously feel that your destiny is changing. If you try to change your destiny and succeed, you will unconsciously feel that Buddha is helping you. You believe that success is the Buddha's help, but you don't believe that failure is the Buddha's giving up. .
