I do not want what i haven't got

I'm walking through the desert
and I am not frightened although it's hot
I have all that I requested
and I do not want what I haven't got

I have learned this from my mother
see how happy she has made me
I will take this road much further
though I know not where it takes me

I have water for my journey
I have bread and I have wine
no longer will I be hungry
for the bread of life is mine

I saw a navy blue bird
flying way above the sea
I walked on and I learned later
that this navy blue bird was me

I returned a paler blue bird
and this is the advice they gave me
"you must not try to be too pure
you must fly closer to the sea"

so I'm walking through the desert
and I am not frightened although it's hot
I have all that I requested
and I do not want what I haven't got
