Look at a gravel driveway, a well-kept lawn or a forest floor in autumn. The grey stone gravel of the driveway covers the ground like a single sumptuous blanket running from the road to the house. It is elegant, it is harmonious and it is as one. Look closer and you see the driveway is made up of different sized gravel. There are many different shapes, different shades of stone, different sizes. Look at the lawn and you will see irregular blades of grass. Look at the floor of a Plane Tree forest and you will not see a single orange leaf that looks exactly like another. It is the way with nature. We see unity in difference.
