Even if time is an artificial construct, light and dark are not. So daylight-saving time may be a convenience of modern civilization, but the equinoxes come to us courtesy of nature. The balance of day with night, light with darkness comes to us again on March 20.

One imagines a great pendulum in the sky, swinging from darkness into light, passing equilibrium with just the barest touch as it makes it steady way to the solstice. On these tender, quiet mornings one can sense the majesty of the universe and the beauty of the earth.

The equinox is a time for balance. Sap is running through the trees and rootlets are seeking moisture where they can. Yards and gardens crave our attention as they awaken. Streets and parkways could benefit from individual T.L.C. Time to lend nature a hand.
