It comes and it goes,
but why? I don’t know.
Just another little mystery
Of life I suppose.

It exposes and hides,
What nature keeps deep inside.
Sometimes it’s quite narrow,
others it stretches out wide.

It ebbs and it swoons,
By the will of the moon.
The old cosmic dance,
To a long ago tune.

It’s the unflappable motion,
from the heart of the ocean.
And to the grains of sand
Shows its quiet devotion.
