there's singing in the mountains, laughter in the trees, dancing in the light of evening fires. There's whispering in hearts and minds and shadows. T… - Patricia Grace

The days before my wedding were full and busy ones but more so for my mother than for any of us. It was summer, with the sun skidding day after day across a flawless ice-blue sky, taking with it all moisture from creeks and pastures, draining the hills and gullies to a sleek ivory. It was the nearest we would get to a white Christmas in these parts.

It's only now that I remember the racket that went on. At the time you become immune to the sounds around you because you're so busy concentrating on where you must go, what you must do to stay alive. There's no room in your head for anything else except your survival. But the roar of guns, the screaming, the din catches up with you eventually.
Also the sights that you see affect you more at a later stage than they do at the time. I won't forget men in a row. I won't forget men on fire. I won't forget a tin hat rolling, spinning across the embankment with the head of a man inside.
Sounds and sights wait inside you, along with the stink of smoke, gunpowder, mud and rot and burning flesh. They invade your waking hours as well as your dreams.

There are reasons we become ill or dispirited. It's what Oriwia was referring to. There's always a cause. Sometimes we bring sickness or punishment upon ourselves through carelessness, distraction, transgression, or failing to dedicate the day or the task. Weak moments may invite wrong forces.
Sometimes sickness is caused by a vengeful person such as Oriwia describes. I have seen those affected by the spite of others become ill, go mad, become lame, turn black, drop dead, die slowly. I have seen their children born with ailments and deformities. (Chapter 25 p198)
