The Bright Field by R S Thomas

I have seen the sun break through
to illuminate a small field
for a while, and gone my way
and forgotten it. But that was the pearl
of great price, the one field that had
treasure in it. I realize now
that I must give all that I have
to possess it. Life is not hurrying

on to a receeding 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.

I found this at 'moot'.
When I googled it to check it was correctly transcribed I discovered it in lots of blogs all over the net so, quite suddenly, something that was fresh and meaningful might already be tired and hackneyed . . . . 
I'll check again later to see which it is, although even a second view (or a tenth) will not necessarily be the truth:
who am I to judge?
