We see this in the life of Napoleon. Some appreciate his life and some do not. But nevertheless during his wars he was the inspiration and power and backbone of the whole country. It was all Napoleon's spirit. And always, even during the greatest anxieties of war, he used to have moments of silence, even sometimes on horseback; and while he was having this silence he would recuperate all the strength lost in the continual responsibilities of war, and he would feel refreshed after having closed his eyes. What was it? He had the key of relaxation. It is tuning oneself to a desired rhythm.
