What is the cause of psychic in Buddhism?

Psychics are ghosts, and they make deals with ghosts as sacrifices. These people are selfish-they covet more than ten years of prosperity, how short life is, and what's more, they go against the sky and prolong life. Become an evil ghost after death, and not drop a drop of rice for millions of years. What's more, they went to hell and suffered a lot.

Buddhist monks and some well-trained laymen will get some magical powers, but it is absolutely impossible for anyone to swindle and cheat for money, because practitioners who can get magical powers know why they can get them, and as long as they have the heart, they will lose them. Only by helping people get out of their misery, increasing their happiness and getting rid of their jobs, will they be willing to use their magical power or subdue evil souls to make people feel confident. There will never be anyone who abuses the avatar.
