This is beautiful, scolds the mind,
Seeing the mind wandering.
It ransacks its lexicon to find
Other words, pondering
Lovely, rare, or perhaps sublime
As sounds with which to hold the mind
That skitters anxiously through time
And which the things in view remind
Of other things undone, unfixed.
Disapproving, the mind regards
Itself distracted, not transfixed.
The whole it had glimpsed: now in shards.
The mind a problem for the mind,
A solid door has shut behind.
