The great advantage of being alive

I desire more poetry on this site. So here is more poetry!

I believe this is Cummings due to the style and some cursory internet searches but I was unable to find an authoritative source. If anyone has one I'll edit it in! The formatting is taken from a book (I discovered this in a photo online).

the great advantage of being alive
(instead of undying)is not so much
that mind no more can disprove than prove
what heart may feel and soul may touch
--the great(my darling) happens to be
that love are in we,that love are in we

and here is a secret they will never share
for whom create is less than have
or one times one than when times where--
that we are in love,that we are in love
with us they've nothing times nothing to do
(for love are in we am in i am in you)

this world(as timorous itsters all
to call their cowardice quite agree)
shall never discover our touch and feel
--for love are in we are in love are in we;
for you are and i am and we are(above
and under all possible worlds)in love

a billion brains may coax undeath
from fancied fact and spaceful time--
no heart can leap,no soul can breathe
but by the sizeless truth of a dream
whose sleep is the sky and the earth and the sea.
For love are in you am in i are in we
