The Warrior of Light

by Paulo Coelho
(quoted randomly)

"Behind the mask of ice that people wear, there beats a heart of fire.
A Warrior knows that an angel and a devil are both competing for his sword hand.

The devil says: "You will weaken. You will not know exactly when. You are afraid." 
The angel says: "You will weaken. You will not know exactly when. You are afraid."

The Warrior is surprised. Both the angel and the devil have said the same thing.
