"Demonic Possession is not a static condition, an unchanging state. Nor does one become Possessed suddenly, the way one might break an arm or catch the measles. Rather, Possession is an ongoing process. A process that affects the two faculties of the soul: the mind, by which an individual receives and internalizes knowledge. And the will, by which an individual chooses to act upon that knowledge.
Ample experience with the Possessed has clearly demonstrated that there are certain identifiable factors that dispose an individual to collaborate, in mind and will, with a Possessing demon. Disposing factors, therefore.
The presence of such disposing factors in a person's life does not in itself portend that the person will surely one day be numbered among the Possessed. At the same time, and with only rare exceptions in my experience, one or several of these disposing factors are operational in genuine cases of Possesion.
Some of the most common dispoing factors have been with us for a long time, while others are of more recent vintage. Some are in the nature of "instruments" outside the individual - the Ouija Board, for example, and the Spiritual Seance. Others are in the nature of "attitudes," whether taught or self-learned, that are interiorized by the person - Transcendental Meditation and the Eneagram Method are two of the most prominent in this category.
In the context of Possession, all disposing factors produce within a person a condition of those two faculties of soul - mind and will - that is most aptly described as an aspiring vacuum. Vacuum, because there is created an absence of clearly defined and humanly acceptable concepts for the mind. Aspiring, because there is a corresponding absence of clearly defined and humanly acceptable goals for the will.
In the case of the Ouija Board, or that of the Seance or TM or the Enneagram Method, the participants must dispose themselves precisely with a view to being opened up; to becoming desirous and accepting of whatever happens along.
The very term, Ouija, for example, is a display of this opening up for the term is composed of the French and German words - Oui and Ja for Yes. The attitude of the participant in Ouija is literally, "Yes, yes." The mind is to be made receptive to whatever suggestions or concepts are presented. If participants also dispose their wills to accept those concepts and act on them, then the predisposing circuit is complete. The aspiring vacuum is operative and is powerful enough to flood the mind with appropriate concepts that can make a bid for the will's assent.
Often enough, the mind and the will are opened up in precisely this fashion in view of Possession."
