There was a certain spirit with me who would think and speak only under the guise of someone else, constantly portraying others whom he happened to know, thus concealing his own identity. These spirits are easily discovered, and they are troublesome, bringing with them from the life of the body this practice of always presenting themselves as others who feel and speak as they do, in order to be convincing, and in the case of some, in order the better to set up their deceptions.
