"The analogies with aphasia, of which we are speaking, may comprise various conditions affecting both medium and communicator. Thus the abnormal physical and mental conditions involved in the trance may affect the integrity of the normal motor action. Then the new situation in which death places a communicator, in relation to any nervous system, may establish conditions very much like aphasia. Then there may be difficulties in the communicator's representing his thoughts in the form necessary to transmit them to and through a foreign organism." Dr. Hyslop then offers the following diagram as a possible solution of certain difficulties involved: [Illustration] A B C represents the normal consciousness; A B D the subliminal consciousness. They intersect at E, which point represents the "equilibrium of the controls." "The area A E B shows the condition in which all sorts of confusion may occur, incidental to the infusion of controls, and this confusion will vary with the relation with the supraliminal and subliminal action of the mind." As one advances, the other recedes. As one gains a greater control over the organism, the other loses it, and _vice versa_. [Illustration] Extending this conception to cover the cases of spirit "possession," in which this varying and fluctuating control is also manifested, we might represent this by the above diagram, in which normal consciousness is left out of account, for the sake of clearness, and the trance condition (subliminal) only represented. The spirit control of the organism takes its place in the diagram. Here A B C represents the trance state--the subliminal consciousness. G D F represents the sphere of the spirit's control. It does not begin at all until the point F be reached. The space A E F represents the area in which all kinds of confusion is possible, and it is within this area that most of the mediumistic messages come. E is the "point of balance." A F H represents the amount of subliminal action accessible to the control, on the one hand, and related to the discarnate, on the other, in its _rapport_. A F represents the amount of the discarnate personality which is accessible to communication, so we have two fields which are wholly inaccessible to each other, and are respectively represented by B C H F and D G I A, the former a portion of the subliminal personality of the living and the latter a portion of the discarnate personality which cannot reveal itself.
