No ruined stones

Stanza from On A Raised Beach (To James H. Whyte) by Hugh MacDiarmid

We must be humble. We are so easily baffled by appearances
And do not realise that these stones are one with the stars.
It makes no difference to them whether they are high or low,
Mountain peak or ocean floor, palace or pigsty
There are plenty of ruined buildings in the world but no ruined stones.
