The whole universe is a complex of rhythms. We each of us feel a need to identify our bodily rhythms with those of the cosmos. The sea is the grand agency of rhythm. The grain-tops in the wind, the atoms that orbit are rhythmic. The uterus, which is a strong muscular organ, contracts with the birth of a baby - the rhythmic contractions, in fact, are the important motivations for the baby to emerge into the world. Rhythm is how it all begins.
