This Prison

I have built these walls
I built this prison
With a flow of a worker's hand
Nothing in me settles down
I'll be your wisdom
With the wealth of freedom, I bought a land
I bought the heart of a man
But I have never told him who I am

I followed rules, earned permissions
I gave the orders my deed command
To be free with you was my mission
I think I never had a chance
I stole the heart of a man
Never gave it back again
I stole the heart of this man
Not ever did I tell him who I am
