Dense about a black bird

Right at my waking, the eye drops,
At the thirteen ways of blackbird

Like white explorer poet is dense
Inside undergrowth of a blackbird,

Preoccupied by his thirteenth way,
Not just number in the last supper

Just being dense about blackbird!
Why thirteen ? do not you ask me.

(Reading a poem “Thirteen Ways of Looking at a Blackbird” by Wallace Stevens)
