The sea and her secrets

Here is a chest whose lid we cannot grasp  
that needs no lock  
that rubs out the messages  
we send her on the sand.

Even the sun cannot fathom her.  
Whole regions of permanent night,  
a wet fist clasping  
the very whole of Earth...

The deeps that lie beneath  
are not for you and me.  
The pearls that gather eternally there  
will ever remain the secrets of the sea.
