The story is known of a person who had put himself in spirit communication so profoundly that the spirits would not leave him alone for one moment. It was just like a telephone ringing at any time of the day. And the most curious thing was that he used to live with them; he used to say, "I don't want you. Go away, go away." But they came again. Day and night the poor man was exposed to the telephone ringing. He could not protect himself once he had laid himself open to them. He had focused himself on the other world, and then he could not close the doors.
