Remembering

There is a tune that enters my mind
after intervals of time
and then exits as a whistle on my lips.
What song it is or where it comes from
I do not know.
It is slow, and sad, and forgetting--
Lost after one time through.
It possesses me for a short time
then wanders away, leaving me wondering.
Such things as these, I believe, are gifts from heaven
A present tied with a silver bow.
Maybe it's just one line from a symphony
I'll play one day in heaven.
Or a seed planted in my heart,
That has just begun to grow.
