Rhythm is at the core of human life. It is, first of all, the rhythm of the organism, ruled by the heartbeat and circulation of blood. As we live in a pulsating, vibrating world, we respond to it and in turn are bound to its rhythm. Without giving much thought to our dependence on the systoles and distoles of flowing time we move through sunrises and sunsets, through the sequences of four seasons. Repetition enables us to form habits and to accept the world as familiar Perhaps the need of a routine is deeply rooted in the very structure of our bodies.
