Following the same psychic law, it will be found that every town or large city, or even every small village or section of a larger town, will be found to have its own distinctive psychic atmosphere, which is very perceptible to strangers visiting the place, and which affect those who take up their residence in the place. In large cities, it has been noticed that every building has its own peculiar vibrations which arise from the general character of those occupying it. Different church buildings likewise reflect the character of the general habits of thought and feeling of those worshipping in them. Likewise, certain business streets have pleasant or unpleasant vibrations in their atmosphere, from the same causes. Every person recognizes the truth of these statements, though but few are able to account for the facts in a scientific manner. The beginner in the study of psychic phenomena often asks how these things can be, when the thought which has occasioned the vibrations have long since passed away. The explanation is simple, when properly explained. It is something like this: just as heat remains in a room after the stove has ceased to throw out heat-waves, so do the vibrations of thought and feeling persist long after the thought or feeling has died away. Or, if you prefer a more material illustration, we may say that if a package of perfumery has been opened in a room, and then removed, the air will remain charged with the odor for a long time afterwards. So, you see, the same principle applies in the case of psychic vibrations. The person carries around with him the general atmosphere of his characteristic mental and emotional vibrations. And, in the same way, the house, store, church, street, town, or city, etc., is permeated with the psychic vibrations of those who have frequented them. Nearly every one realizes the different feeling that impresses him when he enters a strange house, apartment, store or church. Each one has its own difference of psychic effect. And, so does each person create his or her psychic effect upon those coming in contact with him or her, or who comes into his or her presence or vicinity. The next question asked by the thoughtful new student is this: If persons are constantly sending forth psychic vibrations, and if such vibrations persist for some time, why are we not overwhelmed with the force of them; and why are they not all so mixed up as to lose all their effect. I shall now answer this very important question.
