Long before a turning point is evident, tiny shifts lead to change: The last cut of the axe before a tree falls, the gathering force of an avalanche before it lets go, the final few cells piling up to a clot that blocks flow and becomes the stroke, the gradual loosening of a sleepy child’s fingers before the toy slides to the floor, the droop and dangle of a leaf before it drops, the new insight added to insight as a mind is changed.

At autumn equinox, a near balance is struck when day and night are almost the same length before the northern hemisphere tilts toward winter. Minutes of daylight have been slipping away since June, and September’s days, though still sunny, are cooler. I don’t welcome the coming darkness, but accept it. And autumn has its compensations: apples, fires, and glorious colors.
