These particles of vibrating "Thought-stuff" fly off from the brain of the thinker, in all directions, and affect other persons who may come in contact with them. There is an important rule here, however, and that is that they seem to be attracted by those minds which are vibrating in similar thought-rates with themselves, and are but feebly attracted--and in some cases, actually repelled--by minds vibrating on opposite lines of Thought. "Like attracts Like," in the Thought World, and "Birds of a feather flock together," here as elsewhere. Some of these particles of "Thought-stuff" are still in existence, and vibrating, which proceeded from the minds of persons long since dead, the same being emitted or thrown off during the lifetime of the persons, however. Just as a distant star, which was destroyed hundreds of years ago, may have emitted rays which are only now reaching our vision, years after the destruction of the star which emitted them--and just as an odor will remain in a room after the object causing it has departed the particles still remaining and vibrating--and just as a stove removed from a room may leave heat vibrations behind it--so do these particles persist, vibrate, and influence other minds, long after the person who caused them may have passed out of the body. In this way, rooms, houses, neighborhoods, and localities may vibrate with the thoughts of people who lived there long ago, but who have since passed away, or removed. These vibrations affect people living in these places, to a greater or lesser extent, depending upon circumstances, but they may always be counteracted or changed (if they are of undesirable nature) by setting upon positive vibrations on a different plane of mind, or character of thought. The mind of a thinker is constantly emitting or throwing off these particles of "Thought-stuff"; the distance and rate of speed, to and by which they travel, being determined by the "force" used in their production, there being a great difference between the thought of a vigorous thinker, and that emanating from a weak, listless mind. These projections of Thought-stuff have a tendency to mingle with others of a corresponding rate of vibration (depending upon the character of the thought.) Some remain around the places where they were emitted, while others float off like clouds, and obey the Law of Attraction which draws them to persons thinking along similar lines.
