We have several different departments of our systems, I have a vital, a nervous, and a mental system, each of which has actions peculiar to itself—actions which sustain to each other certain relations, either commensurable or incommensurable. Now, when my spiritual and vital systems act upon the same key, there is harmony between my internal and external forms; but if they do not undulate to the same key—if there is not harmonious action between my mind and spirit, I can not be a medium for physical communication, for the same reason that if you graft a peach upon an apple, you can not make it grow (according to my information). It is because the vital action between them is an incommensurable action. Now, whenever my mental action is too intense for my nerve or vital action, if you will by any means reduce my mental action so that it may harmonize with my nervous action, perhaps I will get physical manifestations peculiar to myself. I was once one of those things called mediums, and am now, perhaps, to some extent. When I was partially asleep there would be very loud raps, and if you could come in without waking me up you might get a communication, and it has ever been so when I am peculiarly quiet mentally; but the moment I rouse up and ask questions I can get no reply. There are others who require exactly opposite conditions, whose bodies are too active for their minds, in whose presence you can get rappings by reducing the action of the body. But you change them from that point, the manifestation ceases. There are other individuals who in the normal state seem to comply with all the conditions necessary; that is, whose vital and nervous actions are the same; but you make them angry or stir up within them feelings of dread or fear, and your manifestations cease, simply because there is no harmonic action between the mental and physical systems.
