We can say that there is a spool of thread unwinding. As it unwinds, the thread spirals down. This is one way to describe the unfolding of life and the seeming cycles of spring, summer, autumn, winter — the cycles of everything. That yielding spool of thread is always smoothly in motion. The thread descends like a double helix, and it rises. In My metaphor, it is perpetual. There is no end to the thread. There is no need to put it through a needle to sew the Universe. The thread is circular unto itself.
