Christ Crucified, drawing by St John of the Cross

To reach satisfaction in all 
Desire its possession in nothing,
To come to the knowledge of all
Desire the knowledge of nothing.
To come to possess all
Desire the possession of nothing.
To arrive at being all
Desire to be nothing.
To come to the pleasure you have not
You must go by a way in which you enjoy not.
To come to the knowledge you have not
You must go by a way in which you know not.
To come to the possession you have not
You must go by a way in which you possess not.
To come to be what you are not
You must go by a way in which you are not.
When you turn toward something
You cease to cast yourself upon the all,
For to go from the all to the all
You must possess it without wanting anything.
In this nakedness the spirit finds its rest,
for when it covets nothing
nothing raises it up and nothing weighs it down,
because it stands in the center of its humility.
-- St John of the Cross
