543. A man ought not to speak with any spirit, but a spirit speaks with the man; and they wondered that I spoke so much with them. Hence they could know that there is another kind [of beings than those of their earth]. It is only allowable for a man [of their earth] when he is being punished, to say that he will do so no more; nor is he allowed to tell any of his people that he has spoken with a spirit: this is severely punished.
