But there is a danger in this play. It is interesting to begin with, but then it could be most difficult to get rid of. I have seen a person who had put himself in spirit communication so profoundly that the spirits would not leave him alone one moment. It was just like a telephone ringing every moment of the day. And the most amusing thing is that he used to live with them. The thing that amused me most was his "I do not want you, go away!" But they came again, day and night. Poor man, exposed to the telephone ringing, could not protect himself. Once he laid himself open to them, he focused himself with the other world, and then he could not close the doors. Besides this, it is a great strain on nerves, for the reason that the nerves must be very fine in order to get the communication. The intuitive centers in the body are made of fine nerves, finer than one can imagine.
