How does Janie's journey from west Florida to Eatonville to the everglades represent her and the novel's increasing immersion in black culture?

Janie's journey is one of both self-actualization and
personal and spiritual fulfillment. I'm not so sure her journey is one of increasing
immersion in black culture as it is one of broadening one's horizons and
open-mindedness.

Certainly, as Janie moves from the white
plantation, to her grandmother's house, to Logan's farm, and to Eatonville with Joe
Starks, she is being immersed more and more in black culture. As we learn in Chapter 2,
the first many years of Janie's life she never even realized she was black; she simply
assumed she was white like all the other children on the plantation. By the time she
reaches Eatonville, the all-black town, and runs the store, the "heart of it all" she is
full immersed in black culture.

Her journey with Tea Cake
down into the Everglades, however, represents something different. The society there is
much more diverse and multi-ethnic. From the Haitians, to the Seminole, to the Bahaman
dancers, to the white land-owners, to the racist African Americans such as Mrs. Turner,
Janie encounters individuals and perspectives that are far more broad and
diverse.

Because of this journey, Janie grows to understand
herself. As she says to Pheoby near the end of the novel: "you got tuh
gothere tuh know
there."

Janie does immerse herself in black culture in the
course of the novel but her journey is much more complex than just that. It is a quest
for a kind of global perspective and understanding; as the last three sentences of the
novel tell us:

She pulled in her horizon like a
great fish-net. Pulled it from around the waits of the world and draped it over her
shoulder. So much of life in its meshes! She called in her soul to
see.
