A Single Leaf

This is a poem that came to me one day.

A single leaf lay on the ground
And as it fell made not a sound
A simple thing, so quiet it lay
Leaving behind its greener day
And one would think its job were done
As it rested gently under the sun
Yet as it hugged the chilly ground
Greater things were abound
For with its death the circle renews
A parting gift the Earth will use
And in giving itself to the ground of its birth
A single leaf proves its worth.
