I may see a person in London, if it so happen that the undulation of my mind on this medium be such as to harmonize with that of the individual in London—not that his spirit is personally here present, or my spirit personally present there (but I am here in my own spirit-consciousness, and he there in his spirit-consciousness), but because his image as well as mine is here and there and everywhere else. The idea that my mind goes to London, or his comes here, is altogether a misconception. I perceive that individual in London, not by his absolute presence, but by that which represents that presence here; just as I see you, not by your presence in my mind, but by that which represents your presence there. It is in this way that persons in the body are at times seen as though in distant places; that is, they are seen by that spiritual image which is present, where the mind is unfolded so as to perceive by the spiritual medium, and happens to be in _rapport_ so as to undulate to the same motion with that of the mind of the individual it perceives. Standing here this evening, I may be seen in Philadelphia, because my image is there, as well as in every other place on earth; and the individual, let him be where he may, who happens to be in _rapport_ with me, will perceive me as though I were present where he is, and all the imagery by which I am surrounded. I am looking on this congregation, and therefore the person seeing me, sees me surrounded by this congregation. He does not see you, but since you are in my mind, your image goes with mine. The person coming into _rapport_ with me, sees you as your image exists in my mind. The idea that persons whose external forms are in different places, communicate with each other by being present one with the other, is altogether a mistaken one. So far as the external or relational is concerned—so far as the finite or manifestational is concerned—we communicate externally only by that medium which represents that which we investigate or perceive; and that is the peculiarity of arriving at knowledge through what is called the sphere of manifestation. The difference between being and manifestation is seen in that law.
