Are you mortal if you are heard?

I thought that Gods were mortal
Because their songs are heard
But catching one as sound
Became rather obserd
Perhaps there was a Godcatcher
That captured our sweet bird
And that is why so often
He is heard but not yet seen
Or maybe he can make you think
Your every solumn word
But wherefore art therefore is free will
That makes our very personality
Is it resting somewhere beyond the Gods of us in further tranquility.
Or is he deep inside a soul that lives within the spirit rhelm or a living being without s soul that needeth not a soul to control the body we call home?
Surrounded by the angels that protecteth you and me.
