I can be righteous. I can be blind. I can make you move, or put you in a bind. I can be understandable, or make no sense; Lose control of me, and you'll get no compliments.

I am what men love more than life, fear more than death or mortal strife, what dead men have and rich require. I'm what contented men desire.

I bind without rope, I weigh nothing, yet I crush. I follow you into every choice, But vanish when you know too much.

I live where logic dares not tread, a shadow-play inside your head. I vanish with dawn, like mist in the beam; I am what night invents from scheme.
