Right here I sit,
cross legged, on the second floor.
Under me:
a cushion,
a rug,
a floor,
someone else's a ceiling,
Then another apartment:
a void, furnished and sometimes populated.
another rug,
another wood floor.
Then the basement:
a cluttered void ...
a concrete floor.
Then dirt,
bedrock.
layered crust and mantle,
the Mohorovic Discontinuity,
and the core.
