Contrive a knapsack filled,
carried to the top of a mountain.
Inside is an apple opened
which contains in its core
a knapsack holding a mountain.
Now this is confusing.
There’s an apple below,
a mountain above,
and a core and a knapsack
flanking either side.
Open the knapsack,
this time there’s nothing.
You’re sitting
on top of a mountain
no knapsack, no apple.
