One reads in the books from the East about the different miracles performed by great souls, and one wonders if there is some truth in them. One hears that there are people who know what is going on far away; that there are people who can send their thought from a very great distance; that there are people who can create things, produce things in a moment without having any materials; that there are people who can make things disappear. One even reads and hears that there are some who can command the rain to fall and who can make the multitude move according to their command, their will, and who can inspire the multitude in a flash; who can prevent plagues, and who can perform wonders in war.
