Autumn is the very soul of metamorphosis, a time when the world is poised at the door of winter - which is the door of death - but has not yet fallen. It is a world of contradictions: a time of harvest and plenty but also of cold and hardship. Here we dwell in the midst of life, but we know most keenly that all things must pass away and shrivel. Autumn turns the world from one thing into another. The year is seasoned and wise but not yet decrepit or senile.
