On the Beach

What is the lesson
I've come so far to learn?
Somewhere between invisible
And barely there
A few bubbles
A dimple in the sand
Like a ghost crab trying hard
To avoid capture
Like all things born in water
Drawn back to that familiar
Mother sea
I come to hear her heart
Pound in the tides
Regular and strong
As the blood-tides of my body
The drum that life depends on
Still beating with the elemental
Ocean's pulse.
