There is an external necessity for obeying social laws which must be respected, or society would go to pieces; and there is just as great an internal necessity for obeying spiritual laws to gain our proper self-control and power for use; but we do not recognize that necessity because, while disrregarding the laws of character, we can still live without the appearance of doing harm to the community. Social laws can be respected in the letter but not in the spirit, whereas spiritual laws must be accepted by the individual heart and practiced by the individual will in order to produce any useful result. Each one of us must do the required work in himself. There is no "cure," no help from outside which can bring one to a lasting freedom.
If self-consciousness makes us blush, the more we are troubled the more it increases, until the blushing may become so unbearable that we are tempted to keep away from people altogether; and thus life, so far as human fellowship goes, would become more and more limited. But, when such a limitation is allowed to remain within us, and we make no effort of our own to find its root and to exterminate it, it warps us through and through. If self-consciousness excites us to talk, and we talk on and on to no end, simply allowing the selfish suffering to goad us, the habit weakens our brains so that in time they lose the power of strong consecutive thought and helpful brevity.
If self-consciousness causes us to wriggle, and strain, and stammer, and we do not recognize the root of the trouble and shun it, and learn to yield and quietly relax our nerves and muscles, of course the strain becomes worse. Then, rather than suffer from it any longer, we keep away from people, just as the blushing man is tempted to do. In that case, the strain is still in us, in the back of our brains, so to speak--because we have not faced and overcome it.
Stage fright is an intense form of self-consciousness, but the man who is incapable of stage fright lacks the sensitive temperament required to achieve great power as an artist. The man who overcomes stage fright by getting out of his own way, and by letting the character he is playing, or the music he is interpreting, work through him as a clear, unselfish channel receives new power for his work in the proportion that he shuns his own interfering selfishness.
