Most of our actions or movements are done or made sub-consciously. The reason that "practice makes perfect" is that the sub-conscious mind learns to do the task, and, by so doing, takes it off our hands. How difficult it is to learn to drive a motor-car. How carefully, at first, we have to double de-clutch and obtain the right engine speed for a noiseless "change," yet, after a time, the whole action is performed sub-consciously. It is the same with pianoforte playing. Many players, some better than others, can play the most difficult classical music without consciously recalling it to mind. As soon as they try to remember the whole "piece" leaves them, but as long as they leave the whole matter to the sub-conscious (which never forgets) they can keep on playing. I and my conscious mind are not doing much of the actual writing of this book. We think the thoughts and have something to do with the formation of the sentences, but the sub-conscious mind writes them down. If I had to think of each word and letter, my task would be hopeless, and I should become half dead with fatigue.

The sub-conscious mind, however, is even more helpful, for it does the bulk of our thinking, and can be taught to do a great deal more. If we had to think everything out laboriously, according to the laws of logic, life would be unbearable. Instead of this our sub-conscious mind does the bulk or our thinking, and, if we give it a chance, will do it in an extremely accurate manner, strictly according to the laws of logic and without the slightest fatigue. The more that we train the sub-conscious to do our ordinary thinking for us, the less we suffer from fatigue. Fatigue is unknown to the sub-conscious mind, therefore we can never tire it or overwork it.

The sub-conscious mind can be made to do more and more work for us if we will delegate definite work for it to deal with. One who has learnt thought control, who can take up a matter, consider it in all its bearings, and then dismiss the subject from his conscious thought, is able to increase his efficiency a hundred per cent., and reduce his mental fatigue almost to vanishing point. Instead of laboriously working out his problems and worrying and scheming over them, he simply dismisses them to his sub-conscious mind to be dealt with by a master mind which works unceasingly, with great rapidity, extreme accuracy and entirely without effort. It is necessary, however, to give the sub-conscious every available information, for it possesses no inspiration or super-human wisdom, but works out logically, according to the facts supplied to it.

This great, natural, untiring "mind downstairs," as it has been called, is also capable of doing even more useful work still. A writer or speaker, or preacher can collect notes and ideas for his article, book, speech or sermon, and pass them down to his sub-conscious mind with orders that they be arranged in suitable order, division, sub-division and so on. When he comes either to write or prepare the notes of his speech or sermon, he will find all the work done for him, and all that he has to do is to write it down, entirely without effort or fatigue.

Again, a business man who has learnt to make use of his sub-conscious mind in this way, need not juggle or worry or fatigue himself by planning and scheming for the future. All that he need do is to submit the facts to the "greater mind downstairs," and all the planning will be done for him, entirely without effort, and far more efficiently than he would have done it through laborious conscious thinking.

The following, which has just been brought to my notice, is a striking confirmation of the teaching of this chapter.

In a recent issue of Collier's Magazine, an interview with Henry Ford appeared. He spoke of the way with which big business men deal with problems, and pointed out that they did not spend a lot of time pondering and puzzling over plans or ideas. He said: "An idea comes to us: we think of it for a little while, and then we put it in the pot to boil. We let it simmer for a time, and then take it out." What Henry Ford means, of course, is precisely what we have been saying, viz., that the idea or problem is dismissed to the sub-conscious mind, which works it out, and presents it to the conscious mind for judgment.

Yet again, an inventor or one who is constructing something mechanical, can make use of the sub-conscious mind in precisely the same way. Let him sum up the whole problem, arrange all his facts and available information, and pass them all to his sub-conscious mind, when, if a successful result is within the range of possibility, an answer or idea will be forthcoming. All this being done, mark you, without any effort whatever.

All this may seem, especially to some readers, rather wonderful and far-fetched, yet there is nothing occult or mysterious about it. I am perfectly sure that there is no great writer, politician or business man who does not make use of his sub-conscious mind in this way. He probably does so unconsciously, but his procedure is the same. Some employ the whole of their mind naturally. These become men of achievement, who occupy responsible positions, and who bear immense burdens without strain, worry or care. Responsibility sits lightly upon them, and they are serene and untroubled when in positions, and when confronted by tasks and difficulties, such as would drive an ordinary individual out of his mind. Such men develop their powers of attention and concentration (anyone who is in earnest can do this) to a very high degree. They are at great pains to get to the root of a problem, and obtain all the available data possible, but, after that, it is their sub-conscious mind that does all the work, and which arrives at a decision.

While it comes natural to a few to use their sub-conscious mind in the correct way, the majority of people find themselves unable to do so. Such, however, can acquire the art by training. First, it is necessary to learn thought-control, so as to be able to take up a problem or dismiss it entirely from the mind at will. When a problem is passed on to the sub-conscious to be worked out, the subject must be dismissed entirely from the conscious mind. The problem must not be worried over, nor the thoughts allowed to dwell upon it; it must be left entirely to the sub-conscious. Second, every possible detail and information connected with the problem must be grasped by the conscious mind, and the whole matter, pro and con, visualized before being passed to the sub-conscious. It will be seen, then, that thought-control of a high order is necessary, also powers of attention and concentration. These can all be developed by anyone who is really in earnest.
