"In the big factory of perfecting human souls, the Earth was a kind of tumbler. The same as the kind people use to polish rocks. All souls come here to rub the sharp edges off each other. All of us, we're meant to be worn smooth by conflict and pain of every kind. To be polished. There was nothing bad about this. This wasn't suffering. It was erosion. It was just another, a basic, an important step in the refining process."
