What is the meaning of the irregular, yellow spheres

Pulitzer-prize winning poet Rae Armantrout (1947-) knows how to say so much with so little.

“Exact”

Quick, before you die,
describe

the exact shade
of this hotel carpet.

What is the meaning
of the irregular, yellow

spheres, some
hollow,

gathered in patches
on this bedspread?

If you love me,
worship

the objects
I have caused

to represent me
in my absence.

*

Over and over
tiers

of houses spill
pleasantly

down that hillside.
It

might be possible
to count occurrences.
