Halves

Two halves of a metaphor,
the two sides of the sea:
A coin that keeps rolling,
ever walking the line;
and there are heavy elements
in space above
and lighter dreams beneath
the ocean waves,
and whales toeing
the high rope bridging firmaments,
astronauts walking
the floor of long drowned caves;
and all is its own unending
in the chest of uncarved glyphs
tossed unto the crooked weighing scale
to be measured against possibilities
