Now, let us consider the subject of visualization. Every person knows that the person who wishes to accomplish anything, or who expects to do good work along any line, must first know what he wishes to accomplish. In the degree that he is able to see the thing in his mind's eye—to picture the thing in his imagination—in that degree will he tend to manifest the thing itself in material form and effect.

Sir Francis Galton, an eminent authority upon psychology, says on this point: "The free use of a high visualizing faculty is of much importance in connection with the higher processes of generalized thought. A visual image is the most perfect form of mental representation wherever the shape, position, and relations of objects to space are concerned. The best workmen are those who visualize the whole of what they propose to do before they take a tool in their hands. Strategists, artists of all denominations, physicists who contrive new experiments, and, in short, all who do not follow routine, have need of it. A faculty that is of importance in all technical and artistic occupations, that gives accuracy to our perceptions and justice to our generalizations, is starved by lazy disuse instead of being cultivated judiciously in such a way as will, on the whole, bring best return. I believe that a serious study of the best way of developing and utilizing this faculty, without prejudice to the practice of abstract thought in symbols, is one of the pressing desirata in the yet unformed science of education."

Not only on the ordinary planes is the forming of strong mental images important and useful, but when we come to consider the phenomena of the astral plane we begin to see what an important part is played there by strong mental images or visualized ideas. The better you know what you desire, wish or aspire to, the stronger will be your thought vibrations of that thing, of course. Well, then, the stronger that you are able to picture the thing in your mind—to visualize it to yourself—the stronger will be your actual knowledge and thought-form of that thing. Instead of your thought vibrations being grouped in nebulous forms, lacking shape and distinct figure, as in the ordinary case; when you form strong, clear mental images of what you desire or wish to accomplish, then do the thought vibrations group themselves in clear, strong distinct forms. This being done, when the mind of other persons are affected by induction they get the clear idea of the thought and feeling in your mind, and are strongly influenced thereby.

A little later on, I shall call your attention to the Attractive Power of Thought. But at this point I wish to say to you that while thought certainly attracts to you the things that you think of the most, still the power of the attraction depends very materially upon the clearness and distinctness of the mental image, or thought visualization, of the desired thing that you have set up in your mind. The nearer you can actually see the thing as you wish it to happen, even to the general details, the stronger will be the attractive force thereof. But, I shall leave the discussion of this phase of the subject until I reach it in its proper order. For the present, I shall content myself with urging upon you the importance of a clear mental image, or visualized thought, in the matter of giving force and direction to the idea induced in the minds of other persons. In order for the other persons to actually perceive clearly the idea or feeling induced in them, it is necessary that the idea or feeling be strongly visualized in the mind originating it; that is the whole thing in one sentence.

The next point of importance in thought-influence by induction, is that which is concerned with the process of concentration. Concentration is the act of mental focusing, or bringing to a single point or centre. It is like the work of the sun-glass that converges the rays of the sun to a single tiny point, thus immensely increasing its heat and power. Or, it is like the fine point of a needle that will force its way through where a blunt thing cannot penetrate. Or, it is like the strongly concentrated essence of a chemical substance, of which one drop is as powerful as one pint of the original thing. Think of the concentrated power of a tiny drop of attar of roses—it has within its tiny space the concentrated odor of thousands of roses; one drop of it will make a pint of extract, and a gallon of weaker perfumery! Think of the concentrated power in a lightning flash, as contrasted with the same amount of electricity diffused over a large area. Or, think of the harmless flash of a small amount of gunpowder ignited in the open air, as contrasted with the ignition of the same amount of powder compelled to escape through the small opening in the gun-barrel.

The occult teachings lay great stress upon this power of mental concentration. All students of the occult devote much time and care to the cultivation of the powers of concentration, and the development of the ability to employ them. The average person possesses but a very small amount of concentration, and is able to concentrate his mind for but a few moments at a time. The trained thinker obtains much of his mental power from his acquired ability to concentrate on his task. The occultist trains himself in fixing his concentrated attention upon the matter before him, so as to bring to a focal centre all of his mental forces.

The mind is a very restless thing, and is inclined to dance from one thing to another, tiring of each thing after a few moment's consideration thereof. The average person allows his involuntary attention to rest upon every trifling thing, and to be distracted by the idlest appeals to the senses. He finds it most difficult to either shut out these distracting appeals to the senses, and equally hard to hold the attention to some uninteresting thing. His attention is almost free of control by the will, and the person is a slave to his perceptive powers and to his imagination, instead of, being a master of both.

The occultist, on the contrary, masters his attention, and controls his imagination. He forces the one to concentrate when he wishes it to do so; and he compels the latter to form the mental images he wishes to visualize. But this a far different thing from the self-hypnotization which some persons imagine to be concentration. A writer on the subject has well said: "The trained occultist will concentrate upon a subject or object with a wonderful intensity, seemingly completely absorbed in the subject or object before him, and oblivious to all else in the world. And yet, the task accomplished, or the given time expired, he will detach his mind from the object and will be perfectly fresh, watchful and wide-awake to the next matter before him. There is every difference between being controlled by involuntary attention, which is species of self-hypnotization, and the control of the attention, which is an evidence of mastery." An eminent French psychologist once said: "The authority of the attention is subject to the superior authority of the Ego. I yield it, or I withhold it, as I please. I direct it in turn to several points. I concentrate it upon each point, as long as my will can stand the effort."

In an earlier lesson of this series, I have indicated in a general way the methods whereby one may develop and train his powers of concentration. There is no royal road to concentration; it may be developed only by practice and exercise. The secret consists in managing the attention, so as to fix it upon a subject, no matter how uninteresting; and to hold it there for a reasonable length of time. Practice upon some disagreeable study or other task is good exercise, for it serves to train the will in spite of the influence of more attractive objects or subjects. And this all serves to train the will, remember; for the will is actively concerned in every act of voluntary attention. In fact, attention of this kind is one of the most important and characteristic acts of the will.

So, as you see, in order to be successful in influencing the minds of others by means of mental induction, you must first cultivate a strong feeling of interest in the idea which you wish to induce in the other person, or a strong desire to produce the thing. Interest and desire constitute the fire which generates the stream of will from the water of mind, as some occultists have stated it. Secondly, you must cultivate the faculty of forming strong and clear mental images of the idea or feeling you wish to so induce; you must learn to actually "see" the thing in your imagination, so as to give the idea strength and clearness. Thirdly, you must learn to concentrate your mind and attention upon the idea or feeling, shutting out all other ideas and feelings for the time being; thus you give concentrated force and power to the vibrations and thought-forms which you are projecting.
