God said: Let the dark be dark.
Let the stars shine properly.
And let darkness with no stars
heal the damage caused by light.

Men said: Let there be light all
night through, where there is no-one
much or no-one at all, let
the gathered haze from street-lamps,
undying brand-names, full-blaze
unpopulated windows
stain the undersides of clouds
even when nights are cloudless.

God said: Light itself needs rest.
Some things are best seen, unseen,
in darkness unhindered by
Great Light. Me, for example.
