From The Lemon Trees by Eugenio Montale:

You realize that in silences
things yield and almost betray
their ultimate secrets.
At times, one half expects
to discover an error in Nature,
the still point of reality,
the missing link that will not hold,
the thread we cannot untangle
in order to get at the truth.

You look around. Your mind seeks,
makes harmonies, falls apart
in the perfume, expands
when the day wearies away.
There are silences in which one watches
in every fading human shadow
something divine let go.
