But shortly after the age of forty, her custom of carrying the troubles of all who were near her resulted in a breakdown of health. A story of suffering needless to go into: suffice it that she had many ills to experiment upon, and mental control became suddenly a matter of life and death. In the course of the last five or six years Craig has acquired a fair-sized library of books on the mind, both orthodox scientific, and “crank.” She has sat up half the night studying, marking passages and making notes, seeking to reconcile various doctrines, to know what the mind really is, and how it works, and what can be done with it. Always it was a practical problem: things had to _work_. If now she believes anything, rest assured that it is because she has tried it out in the crucibles of pain, and proved it in her daily regimen. She was not content to see psychic phenomena produced by other persons. Even though authorities warned her that trances might be dangerous, and that _rapport_ with others might lead to dissociations of personality—even so, she had to find out for herself. A hundred times in the course of experiments of which I am going to tell, she has turned to me, saying: “Can you think of any way this can be chance? What can I do to make it more sure?” When I said, the other night: “This settles it for me. I am going to write the story,” her reply was, “Wait a while!” She wants to do more experimenting; but I think that enough is enough. _4_ Two years ago Craig and I heard of a “psychic,” a young foreigner who was astounding physicians of Southern California, performing feats so completely beyond their understanding that they were content to watch without trying to understand. We went to see this young man, and befriended him; he came to our home every day, and his strange demonstrations became familiar to us. He had the ability to produce anaesthesia in many parts of his body, and stick hatpins through his tongue and cheeks without pain; he could go into a deep trance in which his body became rigid and cold; and I put his head on one chair and his heels on another, and stood in the middle, as if he were a two-inch plank. We have a motion picture film, showing a 150-pound rock being broken with a sledge-hammer on his abdomen while he lay in this trance. The vital faculties were so far suspended in this trance that he could be shut up in an airtight coffin and buried underground for several hours; nor was there any hocus-pocus about this—I know physicians who got the coffins and arranged for the tests and watched every detail; in Ventura, California, it was done in a ball park, and a game was played over the grave.
