I do not aim with my hand; he who aims with his hand has forgotten the face of his father. I aim with my eye. I do not shoot with my hand; he who shoots with his hand has forgotten the face of his father. I shoot with my mind. I do not kill with my gun; he who kills with his gun has forgotten the face of his father. I kill with my heart.
Stephen King (2006). “The Dark Tower V: Wolves of the Calla”, p.152, Hachette UK
