It is just like if you exorcise a person, it is the same thing. You get them knocking at your door. Those spirits, they have been living on a person. You have disturbed their life and they don't like it. They don't have anyplace to live. They come and say, "Look here, you have deprived us of our existence!" I know some exorcists whose life has become a complete hell. It is only a very powerful person who can become an exorcist. The responsibility you are taking upon yourself is tremendous. Like Hazrat Inayat Khan, there was a lady who came to him and said, "Oh, I'm obsessed by this being all the time. There are two persons in me. It is so terrible! I'm so confused! I can't go on living like this." Actually, it was the person whom she loved and who was killed during the war. So Murshid said to her, "You're sure that you want to be free of this obsession?" "Oh, yes, Murshid, I can't go on like this!" "All right," said Murshid, "all right." He spoke to the spirit and it is almost as simple, it is like saying, "Go away." You wouldn't believe it, but he went. She came back a few days afterwards and said, "Oh, I feel so poor in myself like this. Oh, please, could you bring him back?" Murshid said, "All right, but once I bring him back I won't be able to exorcise him again. Are you sure that you want him back?" "Yes, I do! I do! Yes!" "All right," said Murshid, "all right."
