This shows that rhythm is a hidden law of nature. The rising and the setting of the sun, the waxing and the waning of the moon, the regular change of the tides in the sea, and the seasons as they come and go, all show rhythm. It is rhythm that makes the birds fly, it is rhythm that makes the creatures of the earth walk. And if we delve deeper into the science of rhythm we shall find that it is rhythm which causes a certain thing to be made in a certain way. If it is made triangular or square or round or five-pointed or whatever geometrical form has been given to it, the reason behind its form is the rhythm of the power that has made it; it is that rhythm which is the cause of its formation.
