Every impulse has its influence upon the word and upon the action. Therefore naturally every impulse exerts its full power through words and deeds unless it is checked. There are two types of persons: those who have learnt to check their word and action when they exert their full power, and express themselves abruptly; the other kind of persons are those who mechanically allow this natural impulse to show itself in their word and deed without giving any thought to it. The former, therefore, is gentle, and the latter is man. Gentleness is the principal thing in the art of personality; one can see how gentleness works as the principal thing in every art. In painting, in drawing, in line and color it is gentleness which appeals most to the soul. The same we see in music. A musician may be qualified enough to play rapidly and may know all the technique, but what produces beauty is his gentle touch.
