Professor Draper, another eminent authority, says: "I find that the cerebrum is absolutely analogous to in construction to any other nervous arc. It is composed of centripetal and centrifugal fibres, having also registering ganglia. If in other nervous arcs the structure is merely automatic, and can display no phenomena of itself, but requires the influence of an external agent—the optical apparatus inert save under the influence of light, the auditory save under the impression of sound—the cerebrum, being precisely analogous in its elementary structure, presupposes the existence of some agent to act through it."
Prof. M. P. Hatfield has said: "The arrangement of the nerve-envelopes is so like that of the best constructed electrical cables that we cannot help thinking that both were constructed to conduct something very much alike. I know that there are those who stoutly maintain that nerve force is not electricity, and it is not in the senses that an electrical battery is not the same thing as a live man; but, nevertheless, nerve-force is closely allied to that wonderful thing that for want of a better and clearer understanding we agree to call 'electricity.'"
Human Etheric Force
Professor Haddock, a popular writer along the lines of scientific psychology and kindred subjects, in a part of his work in which he was considering the idea that thought may be communicated by means of ether-vibrations, forcibly says: "The ether is accepted by science as a reality, and as a medium for light, heat, electricity, magnetism, etc. The nervous system is certainly comparable to an electric battery with connecting wires. Communications of thought and feeling without the mediation of sense-perceptions as commonly understood, is now established. Inanimate objects exert, now and then, 'strange influences.' People certainly carry with them a personal atmosphere. The representation of the condition of these facts by a psychic field, compared to the magnetic or electric field, becomes, therefore, if not plausible, at least convenient. As such a 'field' exists surrounding the sun, so may a 'field' be assumed as surrounding each human individual. 'We have already strong grounds for believing that we live in a medium which conveys to-and-fro movements to us from the sun, and that these movements are electro-magnetic, and that all the transformation of light and heat, and indeed the phenomena of life, are due to the electrical energy which comes to us across the vacuum which exists between us and the sun—a vacuum which is pervaded by the ether, which is a fit medium for the transmission of electro-magnetic waves.' By means, then, of a similar theory applied to mind and brain and body, we may find reasonable explanations of many otherwise insoluble mysteries of life, and, which is of more importance, deduce certain suggestions for the practical regulation of life in the greatest individual interest."
The Brain-Battery
The same writer says: "All states of body and mind involve constant molecular and chemical change. The suggestion arises that the brain, with its millions of cells and its inconceivable changes in substance, may be regarded as a transmitting and receiving battery. The brain being a kind of battery, and the nerves being conductors of released stored-up energy to different parts of the body, by a kind of action similar to the actions of electricity and magnetism, it is suggested that, either by means of the ether, or of some still finer form of matter, discharges of brain energy may be conducted beyond the limits of the body. If the nerve-track corresponds to wires, this refined medium may correspond to the ether-field supposed to be employed in wireless telegraphy. As electrical movements are conducted without wires, or other visible media, so may brain-discharges be conveyed beyond the mechanism of the battery, without the intervention of nerves—except as they may constitute a part of the battery. Generally speaking, such discharges would originate in two ways, viz., by direct mental action, or by mental or physical states—perhaps by a combination."
A Peculiar Organ
So much for the conceptions of modern western science, which agree in the main with those of the ancient oriental occultists, although of course different names and terms are employed. But, we think it worth while to call your attention to the fact that the western scientists have failed to note the significant presence of a peculiar organ in the human body, which is regarded as most important in its functions and offices by the oriental teachers, and which we believe has a very close connection to the subject just discussed by the western scientists. We refer to that strange organ or gland known to western science as the Pineal Gland. Let us see just what this is.
The Pineal Gland
The Pineal Gland is a mass of nervous substance which is found located in the human brain in a position near the middle of the skull, almost directly above the extreme top of the spinal column. It is shaped like a small cone, and is of a reddish-gray color. It lies in front of the cerebellum, and is attached to the third ventricle of the brain. It contains a small quantity of peculiar particles of a gritty, sand-like substance, which is commonly known as "brain sand." It derives its scientific name from its shape, which resembles a pine-cone. Western physiologists are at sea regarding the function and office of this interesting organ, or gland, and the text books generally content themselves with stating that "the functions of the Pineal Gland are not understood." The oriental occultists, on the other hand, claim that the Pineal Gland, with its peculiar arrangement of nerve-cell corpuscles, and its tiny grains of "brain-sand," is intimately associated with certain forms of the transmission and reception of waves of mental vibrations. Western students of occultism have been struck with the remarkable resemblance between the Pineal Gland and a certain part of the receiving apparatus employed in wireless telegraphy, the latter also containing small particles which bear a close resemblance to the "brain-sand" of the Pineal Gland; and this fact is often urged by them to substantiate the theory of the oriental occultists concerning the function and office of this interesting organ of the human body which is located in the brain of man.
Transmission of Thought
Many other facts set forth by modern western science could be cited in our consideration of the question of the existence of any possible organ for the reception of thought vibrations, but it is thought that sufficient evidence of this kind has already been submitted to your attention—sufficient to remove any reasonable doubts, and to give the student at least a clear and open mind on the subject. Summing up such evidence, we may say that modern science is fast approaching the position which is so well expressed by Camille Flammarion, the eminent French scientist, as follows: "The action of one mind upon another at a distance—the transmission of thought, mental suggestion, communication at a distance—all these are not more extraordinary than the action of the magnet on iron, the influence of the moon on the sea, the transportation of the human voice by electricity, the revolution of the chemical constituents of a star by the analysis of its light, or, indeed, all the wonders of contemporary science. Only these psychic communications are of a more elevated kind, and may serve to put us on the track of a knowledge of human nature. What is certain is this: That Telepathy can and ought to be henceforth considered by Science as an incontestible reality; that minds are able to act upon each other without the intervention of the senses; that psychic force exists, though its nature is yet unknown."
A General Principle
At this point we wish to impress upon the minds of the students of this book that what has been above said regarding that class of mental communications generally classed under the head of Telepathy also applies to many much higher phases of occult phenomena and psychic manifestations. In fact, this is one of the reasons why we have paid such close attention to the scientific evidence substantiating this class of phenomena. It is not too much to say that in what has been said in the foregoing pages there is to be found a scientific basis for the phenomenon of "spirit communication," at least in many of its phases. It is but a step in thought—and a natural and easy step at that—from the matter of the communication of thought from the mind of one person or the material plane of life to another person on the same plane, on to the matter of the communication of thought from the mind of an individual entity on a higher plane of life to a second person who is
