Jade Pavilion in the Temple of Heaven: "A mage may not sacrifice five ghosts, five links and other evil spirits." There is another cloud: "Everything is truly immortal, and no one is attached to it. If you don't need to attach people, it is definitely an evil spirit ... those who practice the law should check it. " It's clear here that it's not the immortal who is possessed, but the evil heresy, which is going to be beheaded by the Taoist priest who is practicing dharma. Some possessed people find the next person to possess after this person's death. Because they can tell the story of a person, they are mistaken for reincarnation by some sects without real evidence of practicing dharma. The same is true of "regenerative people".
People possessed by evil spirits will have nightmares, nightmares, hallucinations, even illness and even death. Some people can't stand this torture, and may even hurt their descendants. No matter how much money you spend, it can't be cured unless you meet a real monk. Be careful!
