"Repel all spirits who counsel exclusiveness, division, isolation. Such spirits are always vain and shallow ; they impose on the weak and credulous by exaggerated praises, in order to fascinate and to domineer over them. They are generally spirits who, having been public or private despots while on earth, still desire to have victims to tyrannise over after their death. As a general rule, distrust all communications of a mystic or fantastic character, as well as those which prescribe ceremonies or eccentric actions.
"Absurdities and errors are best got rid of by submitting all spirit-statements to a critical examination. A medium may be fascinated, a group may be imposed upon; but a careful examination of communications, by other groups, with the aid of knowledge already acquired by them and the moral influence of their presidents, and their comparison with those obtained by their principal mediums from spirits of high advancement, will suffice to expose the false statements made, by malevolent or deceptive spirits, to individual mediums or to isolated groups." "ERASTES (Disciple of Saint Paul)"
Remark. - Spirits who wish to make us accept unfounded theories usually pretend that, if we only agree with them, we shall be wiser than everybody else. They do their utmost to avoid the discussion of their theories ; but, if worsted in argument, they disdainfully refuse to reply, and induce their mediums to keep away from the groups by whom their ideas are examined and criticised. Isolation is therefore especially dangerous for mediums, because it leaves them at the mercy of obsessors, who first blind them, and then, too often, lead them astray.
