A Single Day Of Eternity

Miles Davis / John Coltrane: Bye Bye Blackbird

High in the North
in a land called Svithjod
there is a mountain.
It is a hundred miles long
and a hundred miles high
and once every
thousand years
a little bird
comes to this mountain
to sharpen its beak.
When the mountain
has thus been worn away
a single day of eternity
will have passed.
