The Thought-Wave from "The Hidden Side of Things"
Chapter XIX: By What We Think The Realm Of Thought
by CW Leadbeater
The thought-wave is energy.
The action of the thought-vibration is eminently adaptable. It may
exactly reproduce itself, if it finds a mental body which readily
responds to it in every particular; but when this is not the case, it
may nevertheless produce a marked effect along lines broadly similar to
its own.
Suppose, for example, that a Catholic kneels in devotion before an image of the Blessed Virgin. He sends rippling out from him in all directions strong, devotional thought-waves; if they strike upon the mental of astral body of another Catholic, they arouse in him a thought and feeling identical with the original; but if they strike upon a Christian of some other sect, to whom the image of the Blessed Virgin is unfamiliar, they still awaken in him the sentiment of devotion, but that will follow along its accustomed channel, and be directed towards the Christ.
Thought detail 2 by Allison L. Williams Hill
If they touch a Muhammadan they arouse in him devotion to Allah, while in the case of a Hindu the object may be Krishna, and in the case of a Parsi Ahuramazda. They excite devotion of some sort wherever there is a possibility of response to that idea. If this thought-wave touches the mental body of a materialist, to whom the very idea of devotion in any form is unknown, even there it produces an elevating effect; it cannot at once create a type of undulation to which the man is wholly unaccustomed, but its tendency is to stir a higher part of his mental body into some sort of activity, and the effect, though less permanent than in the case of the sympathetic recipient, cannot fail to be good.
The action of an evil or impure thought is governed by the same laws. A man who is so foolish as to allow himself to think of another with hatred or envy, radiates a thought-wave tending to provoke similar passions in others, and though his feeling of hatred is for some one quite unknown to these others, and so it is impossible that they should share his feeling, yet the wave will stir in them an emotion of the same nature towards a totally different person.
