“The acrobat practices: He steps on the edge of a chair and leaps to the floor, feeling the rush as the air flares up his face as he falls. Then he sets himself on something higher, like a table then jumps. He scales a ladder to the ceiling, climbs a tree, pole, watchtower. He keeps increasing the height until no one sees him and the fear to jump leaves him completely, layer by layer [. . .] The acrobat imagines there is a highest possible point in the sky where if he were to fall from it the fall would never end.”
