Is there danger in evoking inferior spirits?

278. An important question arises here, whether or not there is any inconvenience in evoking bad spirits.  That depends on the end one has in view and the ascendancy one can exert over them. The inconvenience is null, when they are called with a serious purpose, which is to instruct and improve them; it is, on the contrary, very great, when called out of mere curiosity or for fun, or even when the caller puts himself at their dependence, asking them for some service.. The good spirits, in this case, can very well give them the power to do what is asked of them, which does not exclude the daredevil who dared to ask for help and suppose them more powerful than God from being severely punished later on. . It will be in vain if he promises himself, whoever does so, to make good use of the help requested from then on, and to dismiss the servant once the service has been rendered. This same service that was requested, however minimal, constitutes a true pact signed with the bad Spirit and he does not easily let go of his prey.. (See no. 212.)  

279. No one exercises ascendancy over inferior spirits, except for moral superiority. Perverse spirits feel that good men dominate them. Against those who are only opposed by the energy of the will, a kind of brute force, they fight and are often the strongest. To someone who was trying to tame a rebellious Spirit, only by the action of his will, he replied to that one: Leave me in peace, with your air of slaughterhouses, which are not worth more than I am; one would say a thief preaching morals to another thief.  

282. 11th. Is there any inconvenience in evoking inferior spirits? And is it to be feared that, by calling them, the summoner will come under their dominion? “They only dominate those who allow themselves to be dominated. He who is assisted by good spirits has nothing to fear. It is imposed on the inferior spirits and not the latter on him. Isolated, mediums, especially beginning ones, must refrain from such evocations.. (No. 278.)
