14. Spirits act upon spiritual fluids, not by manipulating them as men manipulate gas, but by the aid of thought and will. Thought and will are to the spirit that which the hand is to man. By thought they impress these fluids into such and such directions; they agglomerate them, combine or disperse them; they form harmonious wholes of them, which have a definitive appearance, form, and color; they change the properties of them, as a chemist changes those of gas or other bodies by combining them by following certain laws.
Sometimes these transformations are the result of an intention; often they are the product of an unconscious thought. It is sufficient for the spirit only to think of a thing in order that this thing produces itself; it suffices for one to form a melody in one’s mind for it to reverberate through the atmosphere.
Thus, for example, a spirit presents himself to the view of an incarnated being endowed with spiritual sight with the same appearance he had when living at the epoch of their acquaintance, although he may have had many incarnations since that time. He presents himself with the costume, the exterior signs, infirmities, wounds, amputated members, etc., that he had then. A person who has been beheaded will present himself with no head. We do not desire to convey the impression that he has preserved these appearances; no, certainly not; for as a spirit he is neither lame, maimed, blind, nor headless: but, his thought conveying the impression when he was thus, his perispirit takes instantaneously the appearance of it, but it can at the same time leave it instantaneously. If, then, he has been both a black and a white man, he will present himself according to which of these two incarnations may be evoked whence his thought will report itself.
By a similar effect, a spirit’s thought creates fluidicly the objects which he often makes use of. A miser will manage his gold; a military man will have his guns and his uniform; a smoker, his pipe; a workman his plow and his cattle; and an elderly woman, her knitting utensils. These fluidic objects are as real for the spirit, who is also fluidic, as they were in the material state of the living man. However, because they are created by the thought, their existences are also as fleeting as the thought. *
