Circles, by definition, have no ends — each is a continuous line which, as the philosopher Charles Fort tells us, “one measures … beginning anywhere.”
However, like life’s other complexities, not all circles conform to strict definition.
Consider: Earth’s orbit is (mostly) circular, yet because our planet’s rotation is tilted relative to its orbit, the perspective of us surface-dwellers reveals two distinct “ends:” At one, the daily cycle favors light; at the other, darkness. Both make for fine beginnings, even if today’s — which we Northern Hemispherites call “summer solstice” — may be too hot for anything other than thinking.
May the One Who keeps it all in motion favor our undertakings whenever we begin — and so on through their other end.
