The Bright Field - R. S. Thomas

I have seen the sun break through
to illuminate a small field
for a while, and then gone my way
and forgotten it. But that was the pearl
of great price, the one field that has
treasure in it. I realize now
that I must give all I have
to possess it. Life is not hurrying
on to a receding future, nor hankering after
an imagined past. It is the turning
aside like Moses to the miracle
of the lit bush, to a brightness
that seemed as transitory as your youth
once, but is the eternity that awaits you.
