“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.
The devil continues: "Let me help you." And the angel says: "I will help you."
At that moment the Warrior understands the difference. The words may be the same but these two allies are completely different.
And he chooses the angel's hand.”
