The wind, too, has its work to do. The windmill harnesses the freedom of the wind—a biblical symbol for the unfettered spirit—to the ponderous purpose of the millstone. Fleecy clouds and delicate V’s of geese trace the comings and goings of the wind. But only the blades of this mill harness the power of the wind to the service of man. We many not live by bread alone, but when the winds grind flour, we are nourished body and soul.
