sub-stance

I don't want to know you, really, because I won't.
I want to know what you are really about, deep down in your soul, really.
I mean really really. What is burning you in your soul?
I don't want masked gimmicks, really.
I need real substance in a burning soul to be eager to follow, really.
I mean really really and slowly, show me what you are made up of, really really.
Potion in a golden bowl, really.
