Metaphysical Expectorations: Dim Bulb on Watch

A poem by Jim Culleny:

Dim Bulb on Watch —North Atlantic
At sea in a cork
on the back of a frothing bull
grey to infinite horizon,
smack in the middle of it,
stupid in adventure,
bullspit flying everywhere,
lurching twenty, thirty feet per leap
pitching, yawing, rolling, falling,
it never occurred to me
that I might drown.

And so, the dim bulb
of the boy I was
lit my way. And what
dim bulb still does?
