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. A good way of starting the use of the sub-conscious mind is to hold the problem in the mind just as one is going to sleep. There must not, upon any account, be any attempt made to solve the problem or to worry over it. Instead, the main facts of the case, on both sides, must be marshalled, and the case presented to the sub-conscious mind in much the same way as you would place it before your lawyer. Having done this, dismiss the whole matter to your sub-conscious mind, and in most cases you will find in the morning that a solution has been arrived at without any effort or fatigue on your part.
