For the taking of revenge, a man locks himself up alone and thinks. His stomach must be empty for his head to be full. Vengeance comes a little from the heart and a lot from the mind; one must take oneself apart from the noise of men and of things, even from what resembles them; only the voices of bells and of thunder are allowed. Let the room in which you meditate be dark, narrow and warm.
