He perched there, ungravitied as a bird,

knotting his rope and looking about, worlded

in worlds on worlds, pleased, unafraid.

There are no worlds but other worlds

and all the other worlds are here,

reached or almost reachable by the same

outstretching hand, as he, perched upon

his high branch, almost imagined flight.

- from “An Old Man Climbs a Tree”, Wendell Berry
