The Use of the self

"It is important to remember that there is a working balance in the use of all the parts of the organism, and that for this reason the use of the specific part (or parts) in any activity can influence the use of the other parts, and vice versa. Under instinctive direction this working balance becomes habitual and "feels right", and the point at which the influence of the use of any part will make itself felt will vary and the influence of the particular use be strong or weak according to the nature of the stimulus of the end activity desired.If a defect is recognized in the use of a part, and an attempt is made to correct this defect by changing the use of the part without bringing about at the same time a corresponding change in the use of the other parts, the habitual working balance in the use of the whole will be disturbed."
