"For every real lock, there is only one real key
and it's in some other dream, now invisible
it's the key to the one real door
it opens the river and the sky both at once
it's already in the downward river, with my hand on it
my real hand
and I am saying to the hand, turn, open the river"
- W.S. Merwin
(as quoted in "The River Why" by David James Duncan)
