The Contagion of Thought
The same writer says, along the same general lines: "Many have of course noticed the differing mental atmospheres of stores, offices, and other places of business. Some of such places give one an air of confidence and trust; others create a feeling of suspicion and distrust; some convey an impression of active, wideawake management, while others impress one as being behind the times, and suffering from a want of alert, active management. These differing mental atmospheres are caused by the different prevailing mental attitudes of the owners of the respective establishments. The managers of business places send forth thought-waves of their own, and their employees naturally falling into the pace set for them also send forth similar vibrations, and before long the whole place is vibrating on a certain scale. A change of management soon produces a marked change in the entire mental atmosphere of the place. In the same way, we notice the mental atmospheres of the houses we happen to visit; in this way we become conscious of an entire mental scale of many notes, the notes being sounded unconsciously by the minds of the occupants of the houses. From some thresholds radiate harmony, while others breathe the spirit of inharmony. Some radiate emotional warmth, while others chill one like an iceberg, by reason of the emotional coldness of the dwellers therein. Likewise, the low quarters of our cities, the dens of vice, and the haunts of dissipation vibrate with the character of the thought and feeling of those inhabiting them. And, often, the weak-willed visitor is thus tempted. In the same way, certain other places are charged with the vibrations of strong, helpful, elevating mental states, which tend to lift up and elevate, energize and stimulate the minds and feelings of those visiting these places. Thought and feeling are contagious, by reason of the laws of mental vibration and mental induction."
Mental Whirlpools
The contagion of thought-vibrations is manifested by such vibrations coming into contact with the minds of other persons within the field of mental induction of the first person, and there setting up similar vibrations. We know that orators, actors, preachers and others addressing audiences of persons, send forth strong mental currents which tend to awaken corresponding vibrations in the minds of their hearers. We weep, smile, grow angry, feel happy, according to the character of the thought-waves, of the person on the platform or the stage, providing that we accept the same. And, according to the same principle, persons scattered over large areas are influenced and affected in the same way by whirlpools of mental vibrations set into original motion by some strong, masterful public man. A writer has said concerning this point:
Mental Tidal Waves
"We know how great waves of feeling spread over a town, city, or county, sweeping people off their feet, and causing them to lose their balance. Great waves of political enthusiasm, or war-spirit or prejudice for or against certain people, or groups of people, sweep over places and cause men to act in a manner which they afterward often regret when they come to themselves and consider the matter in the light of cold reason. People are swayed by demagogues or magnetic leaders who wish to capture their votes or patronage; and they are often led into acts of mob violence, or similar atrocities, by yielding to these waves of contagious thought. On the other hand, we know equally well how great waves of religious emotion spread out over the community upon the occasion of some great 'revival' excitement or religious fervor."
Immunity to Thought Influences
Persons becoming acquainted for the first time with the above recited facts of mental vibrations, mental currents, mental waves, and mental contagion, frequently raise the objection that if all this be true, why are we not constantly swept off of our feet by these great waves of mental vibrations, whereas, in fact, we are seldom or never aware of them? The question is a natural one, and is capable of a satisfactory answer. In the first place, many of these mental currents neutralize each other, and thus both cease to exert any marked effect. And again, most persons are really "immune" to most of the thought waves reaching them, this by reason of the protective resistive power bestowed by Nature, and acquired during the evolution of the race.
To understand this, we have but to think of our immunity to the great majority of sounds and sights on the streets of a busy city. On a busy street corner, we are assailed by an infinitude of sounds and sightsbut we hear but few of these, and see still fewer. The rest of these impressions are lost to us, although we have ears to hear and eyes to see. We hear and see only those impressions which are strong enough to awaken our attention. In the same way we fail to perceive the numerous thought vibrations and mental currents constantly surrounding us, and our attention is attracted and awakened by those sufficiently strong and vigorous to awaken our attention. The analogy is a very close one, and the understanding of one set of phenomena gives us the key to the other.
Mental Attunement
It should not fail to be noticed, moreover, that we habitually receive and accept more readily those thought vibrations which are in harmony with our own average habitual mental states; and, according to the same general principle, we tend to habitually reject and fail to receive those vibrations which are inharmonious to us for the same reason. Here, you will notice, we have an illustration of the principle of "attunement" which, as we have informed you, is operative on the plane of thought and mental vibrations as well as on that of wireless telegraphy. Just as it is a psychological fact that we tend to see and to hear those things which are in harmony with our beliefs and opinions, and our interest, so is it a metaphysical fact that we tend to accept and absorb the mental vibrations which are in harmony with our opinions, beliefs, and interest, and to reject those which are opposed thereto.
Moreover, the person who acquaints himself with the law of mental vibrations and thought-transference acquires a practical knowledge which enables him to render himself immune to objectionable and undesirable mental currents or thought-waves. We are not necessarily open to the influence of every stray current of thought or feeling that happens to be in our immediate vicinity. Instead, by the proper methods, consciously or unconsciously practiced and manifested, we may, and often do, insulate ourselves so that these undesirable mental influences fail utterly to affect us; and, likewise, we may actually attract to ourselves the desirable mental currents. These principles and methods will be given later in this part of this book; they are mentioned here merely to acquaint you with the fact that they are existent and known to those familiar with this subject.
Voluntary Transmission of Mental Vibrations
Under the head of Voluntary Transmission of Mental Vibrations may be placed the following two general classes of phenomena, viz., (1) Voluntary Efforts to Exert Mental Influence upon Others; and (2) Voluntary Efforts to Produce the Phenomena of Telepathy, along Scientific Lines. Each of these general classes of phenomena will now be presented for your inspection and consideration.
Voluntary Mental Influence
Under the category of Voluntary Mental Influence we find much of the phenomena formerly classed as "Magic"and by this we mean both White Magic, or efforts to produce results beneficial to the person influenced, and Black Magic, or efforts to produce results beneficial to the person exerting the influence, and often to the positive detriment of the person influenced.
