I really noticed the shortening day as I walked to work last night. A couple of months ago, the sun was only just setting as I headed home from class, well after 9:00 — now it is happening before I even arrive. Today is the autumn equinox here in the northern hemisphere (spring equinox in the southern hemisphere), the day when the hours of daylight and darkness stand in balance. It is day to recognize the changing seasons, to express gratitude for what has been, to welcome what comes next, and to seek an inner balance to accompany the outer balance of light and dark.
