Puzzles: lightning spell

In spirit, would be you in word, spirit, would

that I spoke with it

A cloud from heaven

Cloud only

Only a cloud thy

Name, a cloud gathers to utter   

Bears my

spirit against fate mad, within it

could I but once

name your name, g,

A name speaks my wordless spirit, O,

But once, to utter

word never said, one name

only ever

says your name

but if I could but, wish my spirit would  flash,

Say all it could not, but it can, believe, coming thru

harness earth, say it!

your word

real name heard

at your door crash lightning

To speak to your spirit
