Some people claim to have magical powers, so they show people cause and effect, see a doctor, see things, predict, show people possession, perform magical powers, and tell fortune ... these are all big lies. A man who talks nonsense can't even keep the five commandments. He is not a practitioner at all, let alone a "teacher". He must stay away from such people and don't fall for it.
In the precepts of Buddhism and Bodhisattva, it is explicitly forbidden to see cause and effect, see a doctor, see things, predict possession, etc.
A man of practice must be a loyal Buddhist disciple, according to Buddhist scriptures, precepts, the teachings and virtues of eminent monks.
