How does Junior come full circle by the end of The Absolutely True Diary of a Part-Time Indian?

Part of the reason why Junior comes full circle in his
thinking is because he has learned to see the world beyond dualities.  Throughout the
narrative, Junior struggles with being "Indian" or "White."  His world is constructed in
dualities.  Either he lives on the reservation with the Spokanes, or he is at Reardon
with the Whites.  In the end, Mary's death allows Junior to experience several
epiphanies.  He learns that one has to "live life."  This involves following one's
dreams, and while others might not understand this pursuit, it is not something that can
be eliminated entirely for the sake of something else.  His understanding of how alcohol
abuse is a way to deal with the death of one's dreams is a part of this.  Mary might
have died for her own dreams, but they were her own.  When Junior's mother commends
Junior for his path, it is almost a resolution to his own ambivalence.  It confirms that
Junior will always be Indian, but that does not mean that dreams and aspirations are
silenced.  In the end, Junior weeps for understanding from his tribe, and in the
process, seeks to embrace his own dreams, living on the reservation while being able to
experience acceptance from the Whites.  In this light, Junior sees his experience as
unique and distinctive, something that lies outside the realm of binary dualism.  When
he and Rowdy play hoops without keeping score, it represents transcendence from "either/
or" into a transcendent realm.
