To the Air by W. S. Merwin

Just when I needed you
there you were
I cannot say
how long you had been
present all at once
color of the day
as it comes to be seen
color of before
face of forgetting
color of heaven
out of sight within
myself leaving me
all the time only
to return without
question never
could I live without you
never have you
belonged to me
never do I want
you not to be with me
you who have been
the breath of everyone
and of each word spoken
without needing to know
the meaning of any of them
or who was peaking
when you are the wind
where do you start from
when you are still
where do you go
you who become
all the names I have known
and the lives in which
they came and went
invisible friend
go on telling me
again again
