Publisher's Synopsis
Night and day, sleeping and waking, spring and winter, tidal ebb and flow, life and death, all are cyclic. In 24 hours, we breathe in and out 25,920 times, the same as a miniature prescessional sun-cycle. Our heartbeat averages 72 years to pass one degree along its zodiacal circle. In an hour the heart beats 4320 times, the digits of an ancient key cycle. Everything is a cycle.
