46. Just as maladies are the result of physical imperfections which render the body accessible to pernicious exterior influences, obsession is always that of a moral imperfection, which gives place to a bad spirit. To a physical cause one opposes a physical force; to a moral cause it is necessary to oppose a moral force. In order to preserve one’s self from maladies, one must fortify the body; in order to guarantee one’s self against obsession, one must fortify the soul: hence for the obsessed the necessity for working for his own betterment, which is often sufficient to cure obsession without external aid. This aid becomes necessary when obsession degenerates into complete subjugation and possession; for then the patient sometimes loses his volition and free will.
Obsession is nearly always due to a vengeance, exercised by a spirit, and which most often has its source in connections which the obsessed has had with it in a previous existence.
In case of grave obsession the obsessed is enveloped and impregnated with a pernicious fluid, which neutralizes the action of the salutary fluids, and repels them. It is necessary to remove this fluid. Now a bad fluid cannot be repelled by a bad fluid. By an action similar to that of a healing medium in a case of illness, it is necessary to expel the bad fluid by the aid of a better one.
The latter, which is mechanical action, does not always suffice. It is necessary, above all, to act upon the intelligent being, to whom it is necessary to speak with authority, and this authority is given only to moral superiority. The greater the latter is, the greater the authority.
That is not all, however. It is necessary to lead the perverse spirit to renounce his bad designs; to awaken within him a desire to do good, and true repentance, by the aid of cleverly directed instructions, by the evoking of particular spirits to aid him in his moral education. Then one can have the double satisfaction of delivering an incarnated being and of converting an imperfect spirit.
The task is rendered easier if the obsessed, comprehending his situation, joins his will and prayers with yours. It is not thus when the latter, seduced by the deceiving spirit, is deluded in regard to the qualities of his ruler, and delights in the error into which the latter plunges him; for then, far from seconding, he repels all assistance. Such are cases of fascination always vastly more obstinate than the most violent subjugation. (See “The Mediums’ Book,” chap. 23.)
In all cases of obsession prayer is the most powerful auxiliary to act against the obsessing spirit.
