Where does Saul go? Why? Chaper 50-56

In Chapter 51, Saul takes the bus north to Minaki. There he rents a boat and begins traveling downriver, towards Gods Lake. At night he camps on an island in the river, furious as he remembers again and again what Father Leboutilier did to him. Saul finds a stump and hacks at it until he’s exhausted and the rage has subsided, then bathes himself in the river and sleeps through the night. The next day, he reaches Gods Lake and begins walking around the perimeter. As he reaches his old campsite he sees a flotilla of canoes, each boat holding the lost memories of his family. Shabogeesick comes ashore and takes him to the top of a cliff. There, he tells Saul that he is here to learn how to carry Gods Lake within himself. Saul looks down and hears his family singing in low voices, as though praying, while the northern lights suddenly fill the sky. He weeps, finally mourning. Then he looks up at the moon. As he gazes, it becomes the face of a hockey rink, with little Indian boys skating over its surface.
