What does Janie mean about having been to the horizon and back? Hint: What does that have to do with Janie's perceptions of Nanny in chapter 9, page 89?

Back on the porch of her old home in Eatonville with Pheoby, Janie takes her feet out of the pan of water and dries them. She says that she is happy to be home and that the house does not seem so empty as it used to be, because it is now filled with her thoughts and memories. She has been to the horizon and back; she knows now that, "you got tuh go there tuh know there...Two things everybody got tuh do fuh theyselves. They got tuh go tuh God, and they got tuh find out about livin' fuh theyselves." Janie tells Pheoby to explain her story to the townspeople; perhaps they will learn a little about love from her experiences.
