Should poets marvel at the mind
in which appears so many thoughts of diverse kind
and should they think those thoughts are mine
or is their origin somehow divine;
and to avoid a point of some confusion
that you might think I only speak of those that write
what others read and keep in their mind's sight
I should enquire of what you meet;
when in the mind a silence found
in which arrives a thought or sound,
did you see from whence it came
and can you give that source a name?
