Without considering- at all the abstract proposition of the ethical nature of spirit communion, many individuals arc desirous of knowing the modus operandi.

It was stated in our previous discourse that such persons, however, do not take into consideration the fact that tiny have passed through none of the preliminary stages whereby they can understand the methods of spirit communion, but like the child, asking to know astronomy without studying the primary principles either of mathematics or of the laws governing the stellar universe. In the same sense, humanity is wholly in ignorance of the laws governing the communion between the two worlds. But a supposable fact is just as easily stated, even though you do not understand it, and some of those methods I can state to you as realities which may, perchance, only reach your minds in the guise of supposition or possibility, but which, after a lapse of time and greater familiarity with the subject, you will then comprehend.

It is well known that mind influences the physical organism of man, without any known process - that is, no science of physiology, anatomy, or anthropology has yet analytically traced the process by which the individual will power of an embodied human spirit causes the body to walk up and down the streets, the hands to perform the daily task, or any, indeed, of the numberless processes of will.

It is well known that light reaches the human eye by what is termed vibrations; that indeed light itself is but composed of vibrations of the force emanating from the sun through space; that when it comes in contact with the atmosphere of earth there is vibration called light, and that the eye is so accurately and wonderfully constructed that those vibrations produce vision. Only a limited number, however, of the vibrations of light are within human range, and that limited number conlines you to a very narrow realm of vision; objects too small for the human eye to perceive, that is, the vibrations of light upon them being so infinitesimal that you cannot possibly perceive them - make no impression upon the eye. Again, the atmosphere is filled with myriads of living forms of which at the present time, by visual observation, you have no knowledge.

On the other hand, there are objects at so great a distance, or so large, that they do not make any impression upon the retina of the eye, and you cannot by any possible means perceive them without distance being added to you and them, or between you and them; or if they are far distant, you require the aid of telescopic vision to enable you to discover them.

The same is true of every one of the human senses. Sound is but vibration, and certain sounds that transfer a certain number of vibrations make no impression upon the ear except a dull or loud roar. Certain other sounds, like a very faint whisper in a very large room, produce no vibration whatever. The ear is not capable of extension in that direction, but in the universe all these sights and sounds exist, requiring only the adjuncts of science to develop them to your perception. But as the microscope reveals an infinite number of objects not perceptible to the human eye; as the telescope brings within the rays of your vision objects entirely unperceived before, so the added perception of the spirit places at your command numberless vibrations in the occult world that were before unfamiliar.

Baron Von Riechenbach discovered through clairvoyance - the clairvoyant being under his mesmeric control - that every object (not only metals, but plants and human beings) is surrounded by an aura; that aura is more or less magnetic, according to the nature of the object. Certain metals have very distinct magnetic auras, and the sensitive, or clairvoyant, under superior will-power, by the awakening of the inner sense of clairvoyance, could perceive the auras surrounding these various minerals. At last plants were tried, and each plant had an aura much finer than the rays of light that constitute the colors of the petal, extending in a certain direction according to the vibration of light upon the flower. Around human beings also, was discovered by the same process, an aura partaking somewhat of the nature of magnetism, but of a magnetism so fine that it could not be detected either with a galvanic battery or any process of electrical instruments. Nevertheless, an emanation which might be termed nerve fluid, since that represents a finer essence than the vibration of magnetism or electricity. For the want of a better term this was denominated Animal Magnetism, but we choose to call it the nerve force. This force, however, entirely imperceptible to the human eye, is frequently perceptible to the touch; and when you come in contact with an individual whose nerve force or aura is regarded, or may be termed, as positive to yourself, you are affected by it sometimes unpleasantly, sometimes otherwise, but nevertheless it has a palpable effect.

Some persons are so sensitive to these nerve auras, or nerve atmospheres, that they cannot bear close contact in a crowded room with a number of people; and if a very refined and highly sensitive and nervous organism is sitting side by side with one the reverse, the former is obliged often to change his or her seat. This is frequently done unconsciouslv, and frequently these nerve auras make you uncomfortable without your being aware of what disturbs you. Oftentimes vou change your seat in a crowded assemblage or in public conveyances without knowing the impulses that caused you to do it.

If, on the other hand, physical objects, without reference to the mental state, have this impalpable aura, what must it be when accompanied with a mental condition that may, perhaps, be manifested either in sympathy or very much adverse to yours. If you can feel heat and cold that are not visible to the eye, and can feel the magnetic aura of an individual that cannot be analyzed by any sense of the mere physical touch, then what must be the effect of minds in gross condition coming in contact with those who are more refined and sensitive? There is a direct withdrawal of the latter, and closing up as some flowers, like the mimosa, close their petals at the approach of any stranger's touch.
