There can be interference with the transmission of universal forces.
The phenomena of Universal Forces are common, and its interference is too common to be discussed at great length. A tree makes shade when the sun shines; lead plates interfere with x-rays; brass stops magnetism; rubber and glass interfere with the passsage of electricicty, etc., etc. Whether these forces be radiant or conducted, there is a way to interfere with them. If they are being conducted, there is a way to interfere with them. If they are being conducted through matrial, a gap in the conductor will stop their flow; and a diminishing of the size of the conductor will diminish the amount that gets through. As swiftly as the energies travel in the radiant form and with apparant ease, they all prefer to pause, enter, and be conducted by matter. If this were not true, we could have no electricity for use, no compasses, no radio sets, no shade for comfort, and no sunburns. Each of these energies has a preferece for certain kinds of matter. Having these well established facts about natural phenomena, then is it not reasonable to suppose Innates forces might be radiant, but like other forms of energy, prefer a conductor and have a preference for the kind of conductor, which is nerve tissue? And, if this is true, is it not reasonable to suppose, though we cannot see this mental energy, that the impingemement of this living conductor will interfere with the flow? It is true; it is no longer in the realm of theory; it has been proven time and again, when adjustments have gotten sick people well.
