But this power of sending out a subtle influence, call it magnetism or what you will, is not confined to operations upon the human subject. Two ladies of my acquaintance experimented on two rose-trees, which, to all appearances, were both in equally good condition. They daily blessed one and cursed the other, with the result that at the end of a month the anathematized plant had withered up from the roots, while the other was in an abnormally flourishing condition. Nor are we entirely without scientific backing even in such a case as this; for Professor Bose tells us in his work on the "Response of Metals," that not only can they be poisoned by certain chemicals, so as to deprive them of their normal qualities, but that they can be mesmerized into a similar condition. Such facts as these therefore give considerable support to the theory of the existence in everything of a "soul of the subject," which responds after its own manner to the power of human thought.

In what manner, then, is this influence conveyed? It is here that our study of etheric waves comes to our assistance, by carrying the same principle further, and picturing the working of the known Law under unknown conditions. It will at least enable us to form a working hypothesis. I have stated that our actual commercial application of the etheric waves extends from the ultra-violet waves used in photography, and measuring only 1/254,000 of an inch, to those measuring many miles employed in wireless telegraphy; but this practical application by no means exhausts the conceivable possibilities of etheric vibrations; for not only do we find a gap of five octaves of as yet unknown waves between the dark heat group and the Hertzian group, but mathematically there is no limit to the greatness or smallness of the waves, and the scale may be prolonged indefinitely in either direction. Nor is this to be wondered at; for if we consider that vibration is not a progress of individual particles from one place to another, but the alternate rising and falling of the substance at the same point, and that the ether is a homogeneous and universally present substance, it is obvious that there is nothing to limit the minuteness or the greatness of the intervals at which the rising and falling will occur. Therefore we have an unlimited field for our imagination to play about in. Then, if we further reflect that all forms are built up of denser or finer aggregations of ether, and that what determines the generic form of anything is its cosmic soul, or the generating principle of the class to which it belongs, it follows that this soul must have a corresponding form, however inconceivably fine may be the etheric condensation which thus differentiates it from other souls, and prevents it from all being mixed up together in an indistinguishable mass. If now, we combine these two facts, that the soul of anything must have a form, however fine, and that there is no limit either to the greatness or the minuteness of etheric vibrations, we can draw certain deductions from these premises.

It is an established fact of ordinary science that, however closely particles of any substance may seem to cohere, they are in reality separated by interstices through which etheric waves can penetrate.

The principle may be illustrated by the power of the X-rays to penetrate apparently solid bodies, such as iron. Then, if we combine with this the fact, that there is no limit to the minuteness of etheric waves, we see that however fine may be the particles constituting any form, it is always possible to have etheric waves still finer and thus able to penetrate that form and set up vibrations in it. It is our familiarity with the denser modes of matter that makes it difficult for us to grasp the idea of these finer activities; but there is nothing in what we know of the denser modes to contradict the conception; on the contrary, it is just by what we have learned of these denser modes that we reach the principles on which these further conceptions are founded. Looking at this, therefore, in the light of a mathematical proposition, there is absolutely no limit to the fineness of any form, or to its susceptibilities to etheric vibrations.

Finally, to this add the power of the Word to start trains of etheric vibration, and you get the following series: The Word starts the etheric waves; these waves produce corresponding vibration in the soul of the subject; and the soul of the subject in turn communicates corresponding vibration to its body. We may thus explain the Creative Power of Thought on the basis of recognizable Law, and so we believe, because we know why we believe, not because somebody else has told us so. Doubt is still the creative action of Thought, only it is creating negatively; so it is helpful to feel that we have some reason for confidence in the Power of the Word. There are a great many "Thomases" among us, and as one of the number I shall be glad if I can help my "Brother Tommies" to get a grip of the why and wherefore of the things which appear at first sight so fantastic and improbable.

But the conception we are considering is not limited to concrete entities, whether persons or things. It applies to abstractions also, and it is for this reason that I have called it the "Soul of the Subject." We often speak of the "Soul of Music," or the "Soul of Poetry," and so on. Thus our ordinary talk stands on the threshold of a great mystery, which, however, is simple enough in practice. If you want to get a clearer view of any subject than you have at present, address yourself mentally to the abstract soul of that subject, and ask it to tell you about itself, and you will find that it will do so. I do not say that it will do this in any miraculous manner, but what you already know of the subject will range itself into a clearer order, and you will see connections that have not previously occurred to you. Then again, you will find that information of the class required will begin to flow towards you through quite ordinary channels, books, newspapers, or conversation, without your especially laying yourself out to hunt for it; and again, at other times, ideas will come into your mind, you do not know how, but illuminating the subject with a fresh light. I cannot explain how all this takes place. I can only say from personal experience that it happens. But of course we must not throw aside ordinary common-sense. We must sort out the information that comes to us, and compare it with our previous knowledge; in fact we must work at it: there is no premium for laziness. Nor must we expect to receive by a sudden afflatus a complete acquaintance with some subject of which we are entirely ignorant. I do not say that such a thing is altogether impossible, for I cannot venture to limit the possibilities of the Universe; but it is certainly not to be looked for in the ordinary course. I have sometimes been shown specimens of "inspirational painting" done by persons said to be entirely ignorant of art, and the ignorance is very apparent on the face of the work. I dare say an artist may be inspired in the production of a picture, but the technical training comes first, and the inspiration afterwards. The same I believe to be true of all other subjects, so that we come back to the maxim of the power always expressing itself in terms of the instrument through which it works. With this reservation, however, it appears to me, that every class of subject has a sort of soul of its own with which we can put ourselves en rapport by, so to say, mentally unifying our own personality with its abstract principle.

We are told by some teachers, that we can in the same way even construct entities in the nature of our Thought, and possessing a personality of their own with which we have endowed them. Whether this be the case I cannot say—I do not know all the secrets of the invisible. But if our thoughts do not create personal entities able to hang "on their own hook," they create forces which come to much the same thing. They start waves in the Universal etheric medium, which, like the electro-magnetic waves of telegraphy, spread all round from the point of initial impulse, and are picked up whenever a centre happens to be attuned to a similar rate of vibration, and each new centre energizes these vibrations again with a fresh impulse of its own; so in this way thought-currents become very real things.

Such, then, is the power of our Word, whether spoken or only dwelt upon in Thought, to impress itself upon the impersonal element around us, whether in persons or things. We cannot divest it of the power, though we may intensify its action by deliberate use of it, with knowledge of the principle involved, and therefore, whether consciously or unconsciously, we are sending out the influence of our personality all the time.

Now the more we know of these things the greater becomes our responsibility, and I would therefore solemnly warn the reader against any attempt to use the powers now indicated to the injury of any other person, or for the purpose of depriving any one else of that liberty of action which he would wish to enjoy himself. Such use of our mental powers is in direct opposition to the Law of Unity which I have spoken of; and since that Law is the basic principle of the whole Universe, any opposition to it places us in antagonism with a force immeasurably greater than ourselves.

Our Thought always continues to be creative; but in destructive use it becomes creative for destructive forces, and, since it has its origin in our own personality, we are certain sooner or later to feel its effects, on the principle that every action always produces a corresponding reaction. As we have seen, the Law knows nothing of persons, but acts automatically in strict accord with the nature of the power which has set it in motion. Under negative conditions the great Law of the Universe becomes your adversary, and must continue to be so, until by your altered mode of Thought you put yourself in line with it.
