possession of new channels of sense impression, we must never lose sight of the basic fact that all sensations result from contact with vibratory motion. An eminent scientific authority has said regarding this: "The only way the external world affects the nervous system is by means of vibratory motion. Light is vibratory motion; Sound is vibratory motion; Heat is vibratory motion; Touch is vibratory motion; Taste and Smell are vibratory motion. The world is known to us simply by virtue of, and in relation to, the vibratory motion of its particles. Those vibratory motions are appreciated and continued by the nervous system, and by it brought at length to the mind's perception."

The Higher Planes of Nature

In view of the facts and principles above set forth and considered, we may begin to see that there is nothing "unnatural" in the hypothesis that there may be reports conveyed to the consciousness of man by means of higher vibrations than those of ordinary sound, or ordinary sight, providing that man has either (1) highly developed his ordinary senses of sight, hearing, or touch to a degree sufficiently high to register these higher vibrations; or else has evolved and unfolded into consciousness certain latent faculties of sense-impression which are lying dormant in the great masses of mankind. In fact, the thoughtful person will be forced to admit that this new knowledge of the nature of sensations, and of its relation to vibratory motion, renders extremely probable the truth of the great body of reports of such so-called extra-conscious knowledge which the experience of the race has furnished from the beginning of human history down to the present time. Such a person will see that it is not a sign of "credulity" for a person to accept such reports, so universally set forth; but that, rather, it is a sign of "credulity" for a person to accept blindly the dogmatic assertions of the materialistic sceptics to the effect that "there is no such thing possible in the natural world, under natural world, under natural laws—the whole thing is delusion or else deliberate fraud." Such "know-it-all" persons are usually found to really "know much that is not true," and to lack knowledge of much that is true, regarding Nature, her realm and her laws.

An Appeal To Reason.

Concluding these statements, let us say that the student of this book will find nothing contained within this book which is contrary to Nature's laws and principles. He will nowhere in it be asked to suspend the exercise of his reason, and to accept as facts things which violate all of Nature's laws. Instead, he will find at each point full natural explanations of even the most wonderful phenomena; and the appeal to accept same will be made always to his reason, and not to his blind faith or unreasoning belief. The student is urged to build his knowledge of this important subject upon this solid rock of natural law and fact, and not upon the shifting and sinking sands of mere dogmatic assertion and appeal to assumed authority ancient or modern.

PART II

Mental Vibrations and Transmissions

In the category of Nature's Finer Forces must be included that class of manifestations which are generally known as Telepathy, Thought Transference, Thought Force, etc., all of which are based upon the fact that there is present in all such mental states as Thought, Emotion, Desire, etc., a certain rate of vibratory motion, which motion is capable of being radiated from the mind of the person manifesting them in such power and force that they may be registered with more or less distinctness upon the minds of other persons are at a greater or less distance from the first person. In the more common forms of its manifestation, such mental force or power is known as Thought Force, Mental Influence, etc., and in its more pronounced and less common phases it is known as Telepathy, Thought Transference, etc., but the basic principle is precisely the same in all of such cases, simple or complex though their manifestations may be.

The Higher Forces.

We may say here, frankly and plainly, however, that the advanced occultists regard this class of phenomena as comparatively simple and elementary, and therefore not fully entitled to be included in the same category with the higher phases of Nature's Finer Forces, such as, for instance, Clairvoyance, Psychometry, Communication with the Higher Planes, etc. But notwithstanding this, we are of the opinion that any and every one of the finer forces of nature, i.e., any of the forces which are over and above the plane upon which the ordinary senses of man, normally developed, ordinarily function and operate, should be placed in one general category of the Higher Forces of Nature, particularly in a work of this kind designed for the instruction of the general public upon these important subjects. Accordingly, these lesser manifestations of the finer forces in the natural world shall be carefully considered in this part of this book, so that the student may become acquainted with the scientific principles upon which they are based, and may be enabled to develop the power of manifesting such powers if he choose to do so; and that he may understand the nature of such forces and powers when they are manifested by other persons.

Chitta, or Mind Substance.

The Hindu Teachings hold that that which we call "Mind" is not an intangible something different from anything else in Nature, but that, on the contrary, it forms a part of Nature's general manifestation, and is a substantial thing. The Hindus have given to this Mind Substance the name of Chitta. Without going into metaphysical discussion, or entering into technical details concerning this Mind Substance or Chitta, we may say that the Hindus believe it to be one phase of the great Manifestation which we call Nature—just as that which we call Matter is another phase of Manifestation—and, like Matter, having its own particular kind of force, or energy, its own rates of vibrations, and its own attribute of radiating its vibratory force or energy over space. Chitta manifests its activity in creating Thought, Emotions, etc., and also in receiving impressions from the outside world which it translates into perceptions and ideals. Chitta, or Mind Substance, is not regarded by the Hindus as being identical with the Soul, or the Ego; but, on the contrary, they regard it as being an instrument for the expression of the activity of the Ego, or Soul, just as the Body is another kind of instrument. Both Body and Mind are regarded as being intended for the use of the Ego or Soul, and not as identical with the latter. We shall not discuss these distinctions further in this book, this subject being apart from the general field and scope of the present work.

What Modern Science Says.

There are many to whom this conception of the vibration energy of Chitta or Mind Substance may seem strange. But such persons will be still more surprised, perhaps, when they are told that modern science has practically admitted the general truth contained in the Hindu teachings concerning the same, though modern science seems to cloak the facts of the case in technical terms so that the ordinary person is unable to comprehend the real facts dwelling beneath these terms. To this latter class we specially commend the following statement made by Professor Ochorowicz, the eminent European scientist, a few years ago. Professor Ochoriwicz says:

A Living Dynamic Focus.

"Every living being is a dynamic focus. A dynamic focus tends ever to propagate the motion that is proper to it.
