This, in the briefest summary, is the method of teaching the process of conscious control of the muscular mechanisms. I come now to an equally brief consideration of the effects of this method. Speaking generally, I have found that the first immediate effects are a general stimulation and increased efficiency of the whole organism. Nor is this difficult to understand. For it would seem that in the life led by civilised man so little demand is made upon any but the commonly exercised muscles, and these are called upon for comparatively so little effort, that a general sluggishness supervenes, with consequent stagnation resulting in the commonly observed effects of auto-intoxication. With the breaking up of the old motor habits, the muscular mechanisms are brought into full play, the toxins which have accumulated are broken up and disturbed, and increased vitality, a sense of power, and enormously improved efficiency follow as a matter of course. Beyond this, and still speaking generally, I find that there are increased powers of resistance against the attacks of infectious diseases, and—possibly the greatest effect since it guarantees the lasting qualities of the change which is brought about—an ability to check the formation of any bad, incipient muscular or mental habit. This last is, in my opinion, of the very first importance, for it demonstrates the power of the individual, once these principles of conscious guidance and control are mastered, to be the lord of his own body.
