I cite the above authorities merely to give you food for thought, not to attempt to demonstrate to you the fact that thought vibrations exist. The last-named fact has been fully established to the satisfaction of numerous investigators of the subject, and a little reflection will show you that it coincides with your own experiences.
We often hear repeated the well-known Mental Science statement, "Thoughts are Things," and when we say these words consciously realizing just what is the meaning of the statement. We fully comprehend the truth of the statement and the natural consequences of the truth back of it, we understand many things, and are able to use the wonderful power, Thought Force, just as we use any other manifestation of Energy.
As I have said, when we think we set into motion vibrations of a very high degree, but just as real as the vibrations of light, heat, sound, electricity. And when we understand the laws governing the production and transmission of these vibrations we will be able to use them in our daily life, just as we do the better known forms of energy. That we cannot see, hear, weigh or measure these vibrations is no proof that they do not exist. There exist waves of sound which no human ear can hear, although some of these are undoubtedly registered by the ear of some of the insects, and others are caught by delicate scientific instruments invented by us; yet there is a great gap between the sounds registered by the most delicate instrument and the limit which the human mind, reasoning by analogy, knows to be the boundary line between sound waves and some other forms of vibration. And there are light waves which the human eye does not register, some of which may be detected by more delicate instruments, and many more so fine that the instrument has not yet been invented which will detect them, although improvements are being made every year and the unexplored field gradually lessened.
Thought Vibration

These thought vibrations, likewise, cannot be seen, tasted, smelled, heard nor felt in the ordinary way; although it is true there are on record cases of persons peculiarly sensitive to psychic impressions who have perceived powerful thought-waves, and very many of us can testify that we have distinctly felt the thought vibrations of others, both whilst in the presence of the sender and at a distance. Telepathy and its kindred phenomena are not idle dreams.
Light and heat are manifested by vibrations of a far lower intensity than those of Thought, but the difference is solely in the rate of vibration. The annals of science throw an interesting light upon this question. Prof. Elisha Gray, an eminent scientist, says in his little book, "The Miracles of Nature":
"There is much food for speculation in the thought that there exist sound-waves that no human ear can hear, and color-waves of light that no eye can see. The long, dark, soundless space between 40,000 and 400,000,000,000,000 vibrations per second, and the infinity of range beyond 700,000,000,000,000 vibrations per second, where light ceases, in the universe of motion, makes it possible to indulge in speculation."
M. M. Williams, in his work entitled "Short Chapters in Science," says:
"There is no gradation between the most rapid undulations or trembling's that produce our sensation of sound, and the slowest of those which give rise to our sensations of gentlest warmth. There is a huge gap between them, wide enough to include another world of motion, all lying between our world of sound and our world of heat and light; and there is no good reason whatever for supposing that matter is incapable of such intermediate activity, or that such activity may not give rise to intermediate sensations, provided there are organs for taking up and sensifying their movements."
