on the physical, on the astral, on the mental, or on the buḍḍhic plane. It does not matter in what world you are moving, in what matter your consciousness is acting; so long as it is utilising organised matter for its own expression so long are those manifestations psychic, and are properly included under the term psychism. You may perhaps wonder why I lay stress on this. You will see it at once if I remind you that unless we keep this definition in mind—accurate, legitimate as it is—we shall be making a division between the manifestation of the consciousness on the physical and on the astral and mental planes, between its manifestation in the physical and those in the astral and mental bodies; and if we do that the whole of our thought will be on mistaken lines. You need practically to be pressed back to what you know of consciousness on the physical plane, before you can thoroughly follow its manifestations on the astral and on the mental. If you try to separate off manifestations which are the same in kind though differing in degree, according to the fineness of the matter which is employed, if you try to separate them off, you will always regard what you call psychism—that is, astral and mental manifestations in the subtler bodies—in an artificial and unwise manner. If, on the other hand, you realise that consciousness is one, that its manifestation on any plane is conditioned by the matter of the plane, that it is one in essence, only varying in degree according to the lessening or the increase of the resistance of the matter of the planes, then you will not be inclined to take up exaggerated views with regard to what people are so fond of calling psychism. You will not denounce it in the foolish way of many people, because in denouncing it you will know that you denounce all intellectual manifestations, an absurdity of which very few people are likely to be guilty; if you take your intellectual manifestations in the physical world as admirable things, to be always encouraged, strengthened, developed, then you will be compelled, by parity of reasoning, to understand that the manifestations of the same consciousness in finer matter, astral or mental, are equally worthy, and no more worthy, of development, of consideration. You will not find yourself in the absurdly illogical position of declaring it a good thing to train the physical plane consciousness, while it is dangerous to cultivate the astral and mental plane consciousness. You will understand that all psychism is of the same kind, that on each plane the development of psychism has its own laws; but that it is absurd to admire the working of consciousness on the lower plane, and shrink from it as something dangerous, almost diabolical, when it appears on a plane higher than the physical.
It is this rational and common-sense view which I want to impress upon you to-night, to get you out of the region of mystery, marvel, wonder, and fear, which to so many people surround what is called psychism; to make you understand that you are unfolding consciousness, showing out your powers on one plane after another according to the organisation and the fineness of the bodies in which your consciousness is working; and that if you will only keep your common sense and reason, if you will only not allow yourself to be terrified by what at present is unusual, you may then walk along the psychic pathway in the astral or mental world, as resolutely, and with as great an absence of hysteria, as you walk along the psychic pathway in the physical world. That is the general idea; and, of course, this is the meaning in which, after all, the word is often used down here. When you say "psychology" you do not mean only the workings of consciousness in astral and mental bodies; you mean the whole consciousness of the man, the workings of the mind, wherever the mind is active; the whole of that you include under "psychology." Why, then, when you change its form, should you narrow it down, as though that which is mind on one plane is not also mind on all planes on which the mind is able to function?
Now let us consider for a moment the workings of the mind on the physical plane: they are familiar. There is, however, one important point about them. In the materialistic science of the last century you had very widely spread, amongst scientific men, the view that thought was only the result of certain kinds of vibration in certain kinds of matter. I need not dwell on that. But you are aware that both in England, and more especially in France and Germany, most elaborate disquisitions were written to prove that thought was only the product of nervous matter. You rarely, I think never, now find a well-trained scientist prepared to commit himself to that position. Those who survive as representatives of that same school may do so, but they are literally survivals. The mass of psychologists of to-day admit that the manifestations of mind cannot any longer be regarded as the results of vibrations in the physical brain, that at least we must go beyond these limitations when dealing with the results of the study of consciousness, as it is now studied amongst scientific men. They will no longer, then, regard thought as the product of matter. They certainly will not be prepared to go as far as I now propose to go, and say that the thinking organism is the production of thought—the very antithesis, you will agree, of the other position, but which is vital to the understanding of the unfolding of the powers of consciousness through matter. It is recognised in ordinary biology that the function appears before the organ. There I am on safe scientific ground. It is recognised that the exercise of the function gradually builds up the organ. All the researches into the simpler forms of organisms go to prove that. It is also recognised that when the exercise of the function has built the organ in a very simple form, the exercise of the function continually improves the organ which originally it builded. So far we are hand in hand with ordinary science. I think I shall not go too far in saying that a large number of the more scientific psychologists of to-day will at least agree that the brain as you find it in the adult man is very largely the result of the exercise of thinking through the earlier years of life. I do not think they would go so far as to say that thinking has literally produced it. They would, however, judging by very many things that have been said, be willing to admit that by hard thinking we can improve our apparatus of thought. That is one reason for thinking hard—in order to think better. And the harder you think, the more will your thinking instrument improve.
In my next step, however, I cannot by any stretching of ordinary science persuade it to accompany me, or give me a foundation; for the point is that your consciousness, working on the next plane above the one on which the organ of consciousness is being built, is the shaper of that mechanism. To put it concretely: your physical brain is built up from the astral plane, and it is your consciousness working in matter finer than the physical which builds up the brain in the forming child within the limits laid down by karma. Now, that is a general law for healthy evolution. You will see the importance of this law a little further on. Every body which we possess—physical, astral, mental, buḍḍhic—is always built up by consciousness working in the plane next above it; the next plane, or world, is a world very much more "next" than you are next each other sitting here—not far away beyond the stars, removed by great spaces. It is interpenetrating you in every portion of your being. It is only "next" in the sense that the solids, liquids, and gases of your bodies are next each other in the body—not far away, but here. So that the working is of the closest and most intimate kind. Some of you who are students of Theosophical literature will remember that H.P.B. has spoken of all of us as working in the astral consciousness. You will see that you are not working with a physical consciousness in the literal sense of the term, if you think for a moment. How much do you know of the consciousness working in the various cells and tissues of your physical body? Practically nothing, except when you are ill. Only when the body is disorganised do you become conscious of that working. Normally, the motion of your blood, the building up by assimilation of your muscles and nerves, the life of your cells, the protective action of some of the living cells in your body—the "devourers," as they are called—go on without your knowledge, without your thought, without your giving one moment's conscious attention to them. In the Perfect Man, the consciousness of all this is ever present, but in us, imperfect, it is not; we are not yet sufficiently vitalised and unfolded to carry on the whole of our consciousness, with full awareness of all its activities. We are only able to manage a very small part of it, and so have let go the consciousness that keeps at work the physical body, to concentrate ourselves in a higher world, and utilise the nervous mechanism as the apparatus of our thinking. That law obtains, then, all through. If you want to organise and build up your astral body, you can only do it from the mental plane. You must raise your thought to a higher power by concentration, by regular meditation, by deliberately working on the consciousness, before you can raise it to that power from which it shall be able to organise your astral body, as it has already organised your physical body. That is the reason why meditation is necessary in all these things; because without the
