The cold remote islands
And the blue estuaries
Where what breathes, breathes
The restless wind of the inlets,
And what drinks, drinks
The incoming tide;

Where shell and weed
Wait upon the salt wash of the sea,
And the clear nights of stars
Swing their lights westward
To set behind the land;

Where the pulse clinging to the rocks
Renews itself forever;
Where, again on cloudless nights,
The water reflects
The firmament’s partial setting;

—O remember
In your narrowing dark hours
That more things move
Than blood in the heart.
Louise Bogan “Night” from The Blue Estuaries

 I know what my heart is like
Since your love died:
It is like a hollow ledge
Holding a little pool
Left there by the tide,
A little tepid pool,
Drying inward from the edge.
~Edna St. Vincent Millay “Ebb”

My mother was 58 when my father left her for a younger woman. 

For months, she withered,
her heart broken, her pulse erratic,
crying until there were no more tears left.

She began drying inward from her edges
despite the ebbing and flowing
of her heartbeat.

It took ten years,
but he came back like an overdue high tide.  

She was sure her love had died
but that tepid pool refilled
with water cool to the touch,
yet overflowing.
