Three nights ago, according to the planets and the stars, autumn began. For those of us walking through the forest to the Retreat House or splitting wood beside Homestead, the season's edges are less defined. For days and days the trees have stood green and glowing, suffused with shimmering sunlight as the air blows alternately warm and cool around them. Then a crimson leaf appears on the path to the front door and the maple and buckeye next to Homestead are tinged red and yellow. The scruffy, molting cardinals are shaking off their summer plumage, replacing feathers to stem winter's chill. Second by second, dark cloaks the earth earlier each night; songbirds are departing; we hunt in our closets for sweaters and quilts. All around, here and there, incremental but persistent change is happening.
