Summary of the Book of the Puzzle of the Lacuris

From time to time we hear about someone, somewhere, possess supernatural abilities, and do strange acts that most people cannot. He walks on the burning embers, swallows the pieces of glass, moves things without touching them, and perhaps a person was exposed to visions of vigilance or a dream and tell people to make fun of it, if they really come true after a day or two! What are the truth of these things? Is there hidden creatures that help such people? Or is all this lies and myths circulated by tongues, what if you see with your eyes a person who enters a sword in his stomach and takes it out of the other side! Then he pulls him and completes his life as if nothing happened. Will your eyesight lie too?
