"We cannot step twice into the same river, for fresh waters are ever flowing in upon us." — Heraclitus

 

The swirling river under the bridge

becomes a fulcrum for the tides,

 

nothing but tidal waters flow

back and forth, on a given day, new

 

currents come in and go out

in ever changing constancy.

 

High tide turns water blue against

a far-off ring of green trees

 

winds ripple low tides to whitecaps,

turning the sea’s hue to blue-grey

 

over shadows of shoals; boats at moorings

point as if parked by attendants.

 

Fresh water streams flow only

one way and vanish into the sun.

 

I speak these lines in awe

because Nature makes an exception

 

to remind us of her cycles, allowing

us to step twice into the same river.
