You cannot see the wind. You can feel its breath on your skin,but you cannot see it. It is only the swaying of the trees that betrays it presence. Tree branches are a device for visualizing the wind.
Trees are supple and pliant.
They yield softly, letting the wind pass through. They do not fight the wind. They do not fight,but are never defeated. When the wind dies down they regain their original shape. This is not so with things people make.
