Ordinary life is like a pendulum, ceaselessly swinging back and forth. The peaceful person remains calm until he is ready to work; then he swings into action. As soon as he is through, he swings back to the center of calmness. You should always be calm, like the pendulum that is still, but ready to swing into steady action whenever necessary.
To be calmly active and actively calm—a Prince of Peace sitting on the throne of poise, directing the kingdom of activity—is to be spiritually healthy. Too much activity makes one an automaton and too much calmness makes one lazy and impractical.
