Harmony

I wonder at the patterns in the sand
How they got there
The intricate harmonies of line and shape
What could create such beauty?

Then the wave comes
And I wonder anew
At the interplay of moving water and sand
The rivulets and eddies and smaller waves

Then I wonder
Does the wave cause the beauty in the sand
Does the sand cause the beauty in the wave
Which creates which?

Then I understand
The harmony of sand and sea
I realize the beauty of each
Is created by the harmony of all
