"Take down the walls. 
That is, after all, the whole point. 
You do not know what will happen if you take down the walls; you cannot see through to the other side, don't know whether it will bring freedom or ruin, resolution or chaos. It might be paradise or destruction. 
Take down the walls.
Otherwise you must live closely, in fear, building barricades against the unknown, saying prayers against the darkness, speaking verse of terror and tightness.
Otherwise you may never know hell; but you will not find heaven, either. You will not know fresh air and flying.
All of you, wherever you are: in your spiny cities, or your one bump towns. Find it, the hard stuff, the links of metal and chink, the fragments of stone filling you stomach. 
And pull, and pull, and pull.
I will make a pact with you: I will do it if you will do it, always and forever.
Take down the walls." 
― Lauren Oliver, Requiem
