Sé tu propio palacio, o la cárcel de tu mundo.” - John Donne

Build therefore your own world.

Study the prison you have inadvertently built around yourself.

Make your own rules or be a slave to another man's.

The World exists for you ; Build therefore your own world

The world is a prison in which solitary confinement is preferable.

You must decide if you are going to rob the world or bless it with the rich, valuable, potent, untapped resources locked away within you.

La mente es tu propio palacio y puede hacer un infierno del cielo o un cielo del infierno” – John Milton, El paraíso perdido.

"Power said to the world,
"You are mine."
The world kept it prisoner on her throne.
Love said to the world, "I am thine."
The world gave it the freedom of her house."

This is the world you have made yourself, now you have to live in it.

The mind is its own place, and in itself / Can make a Heaven of Hell, a Hell of Heaven. / What matter where, if I be still the same...

Those who build walls are their own prisoners.

Every spirit builds itself a house; and beyond its house, a world; and beyond its world a heaven. Know then, that the world exists for you: build, therefore, your own world.

Rule your mind or it will rule you.
