There if you like is black and white magic. I believe that there are people in the world so crushed by fear and wickedness that every breath of their bodies and every glance of their eyes is a blight on all who come near them, and I believe that there are people who are so fearless and good that where they walk, health and happiness spreads round them as an aura, as sunlight on every life that touches them.
