“Remember what I told you before; namely – and you’ll know it still, I hope – that it is possible for one eye alone, open or closed, to achieve an effect of terror, beauty, grief, or love, or what have you. It doesn’t take much to show love, but at some time or another in your, praise God, disastrous life you must have felt, honestly and simply, what love is and how love likes to behave. It is the same, naturally, with anger also, and with feelings of speechless grief; briefly, with every human feeling. Incidentally, I advise you to perform athletic exercises often in your room, to go for walks in the forest, to fortify the wings of your lungs, to practice sports, but only select and balanced sports, to go to the circus and observe the behavior of the clowns, and then seriously to consider by which rapid movements of your body you can best render a spasm of the soul. The stage is the open, sensual throat of poetry, and dear sir, it is your legs that can strikingly manifest quite definite states of the soul, not to mention your face and its thousand mimings. You must take possession of your hair, if, in order to manifest fright, it is to stand on end, so that the spectators, who are bankers and grocers, will gaze at you in horror.”
