You are on a cross-channel boat on a roughish passage. You go up to a sailor and say to him in a sympathetic tone: "My dear fellow, you're looking very ill. Aren't you going to be sea-sick?" According to his temperament he either laughs at your "joke" or expresses a pardonable irritation. But he does not become sick because the associations called up are contrary ones. Sea-sickness is associated in his mind with his own immunity from it, and therefore evokes not fear but self-confidence. Pursuing your somewhat inhumane experiment you approach a timid-looking passenger. "My dear sir, how ill you look! I feel sure you are going to be sea-sick. Let me help you down below." He turns pale. The word "sea-sickness" associates itself with his own fears and forebodings. He accepts your aid down to his berth and there the pernicious autosuggestion is realised. In the first case the idea was refused, because it was overwhelmed by a contrary association; in the second the Unconscious accepted it, since it was reinforced by similar ideas from within.
But supposing to a sick mind, permeated with thoughts of disease, a thought of health is presented. How can we avoid the malassociation which tends to neutralise it?
We can think of the Unconscious as a tide which ebbs and flows. In sleep it seems to submerge the conscious altogether, while at our moments of full wakefulness, when the attention and will are both at work, the tide is at its lowest ebb. Between these two extremes are any number of intermediary levels. When we are drowsy, dreamy, lulled into a gentle reverie by music or by a picture or a poem, the Unconscious tide is high; the more wakeful and alert we become the lower it sinks. This submersion of the conscious mind is called by Baudouin the "Outcropping of the Subconscious." The highest degree of outcropping, compatible with the conscious direction of our thoughts, occurs just before we fall asleep and just after we wake.
It is fairly obvious that the greater the outcropping the more accessible these dynamic strata of the mind become, and the easier it is to implant there any idea we wish to realise.
As the Unconscious tide rises the active levels of the mind are overflowed; thought is released from its task of serving our conscious aims in the real world of matter, and moves among the more primal wishes and desires which people the Unconscious, like a diver walking the strange world beneath the sea. But the laws by which thought is governed on this sub-surface level are not those of our ordinary waking consciousness. During outcropping association by contraries does not seem readily to take place. Thus the mal-association, which neutralised the desired idea and so prevented acceptation, no longer presents itself. We all know what happens during a "day-dream" or "brown-study," when the Unconscious tide is high. A succession of bright images glides smoothly through the mind. The original thought spins itself on and on; no obstacles seem to stop it, no questions of probability arise; we are cut off from the actual conditions of life and live in a world where all things are possible. These day-dreams cause very potent autosuggestions, and one should take care that they are wholesome and innocent; but the important point is that on this level of consciousness association seems to operate by similarity, and emotion is comparatively intense. These conditions are highly favourable to acceptation.
If, on getting into bed at night, we assume a comfortable posture, relax our muscles and close our eyes, we fall naturally into a stage of semi-consciousness akin to that of day-dreaming. If now we introduce into the mind any desired idea, it is freed from the inhibiting associations of daily life, associates itself by similarity, and attracts emotion of the same quality as its own charge. The Unconscious is thus caused to accept it, and inevitably it is turned into an autosuggestion. Every time we repeat this process the associative power of the idea is increased, its emotional value grows greater, and the autosuggestion resulting from it is more powerful. By this means we can induce the Unconscious to accept an idea, the normal associations of which are contrary and unfavourable. The person with a disease-soaked mind can gradually implant ideas of health, filling his Unconscious daily with healing thoughts. The instrument we use is Thought, and the condition essential to success is that the conscious mind shall be lulled to rest.
Systems which hitherto have tried to make use of autosuggestion have failed to secure reliable results because they did not place their reliance on Thought, but tried to compel the Unconscious to accept an idea by exercising the Will. Obviously, such attempts are doomed to failure. By using the will we automatically wake ourselves up, suppress the encroaching tide of the Unconscious, and thereby destroy the condition by which alone we can succeed.
It is worth our while to note more closely how this happens. A sufferer, whose mind is filled with thoughts of ill-health, sits down to compel himself to accept a good suggestion. He calls up a thought of health and makes an effort of the will to impress it on the Unconscious. This effort restores him to full wakefulness and so evokes the customary association—disease. Consequently, he finds himself contemplating the exact opposite of what he desired. He summons his will again and recalls the healthful thought, but since he is now wider awake than ever, association is even more rapid and powerful than before. The disease-thought is now in full possession of his mind and all the efforts of his will fail to dislodge it. Indeed the harder he struggles the more fully the evil thought possesses him.
This gives us a glimpse of the new and startling discovery to which Coué's uniform success is due; namely, that when the will is in conflict with an idea, the idea invariably gains the day. This is true, of course, not only of Induced Autosuggestion, but also of the spontaneous suggestions which occur in daily life. A few examples will make this clear.
Most of us know how, when we have some difficult duty to perform, a chance word of discouragement will dwell in the mind, eating away our self-confidence and attuning our minds to failure. All the efforts of our will fail to throw it off; indeed, the more we struggle against it the more we become obsessed with it.
