Looking for a Vein

I'm down in this hole again Trying to find a vein or something Hammering these walls and hoping Hoping I find my way through But what if I strike it? Rich as I wanna be Will it set me free or be just another hole to dig? I can't give up on this What am I supposed to do? Hammering these walls down here Trying to find a way out But what if I strike it? Rich as I want to be Will it set me free, or be just another hole to dig? What will it mean? What will it mean? What will it mean? What does it matter? But I can't give up on this Always trying to break on through This air is choking me But hammering is all I know to do Do you remember, when I was digging again? I can't stop looking, but what am I looking at? What will it mean? What will it mean? What will it mean? What does it matter? Maybe I'll find the vein Hammering these walls and hoping
