Cermony - Silko

Tayo begins his journey as a traumatized WWII vet. After your brother/cousin dies in your arms, you'd naturally experience some survivor's guilt, but Tayo doesn't stop there. Tayo takes on the burden for his uncle's death, mother's alcoholic destruction, and the drought that plagues his people.
No wonder he feels like puking all the time.
He returns home and is cared for by his aunt and uncle who gradually lose patients with his condition and suggest the help of a medicine man. Although Tayo originally attempts to numb his anguish in beer with the other Laguna vets, he cannot find solace in the stories they swap, stories of when they were appreciated and admired by other Americans. He finally snaps and stabs Emo, rattling his can of deadmen's teeth.
The healer Betonie is one of the few that can understand Tayo's predicament, how he lost his way on the hoop of time.  A half-blood like Tayo, he can understand how Tayo has felt isolated from both cultures. He sets him out on his spiritual journey to turn back the witchery and find purpose again.
Tayo tries again to complete Josiah's dream of raising a hardy, yet meaty cattle and sets out to reclaim them. Along the way he runs into the mystical T'seh and has a healing sexual experience with her.
He spends the summer with T'seh, but eventually the witchery shows up again. Emo is on the hunt for Tayo, but settles on mutilating and killing his friend Harley instead. Tayo resists the urge to attack Emo and the witchery consumes itself, Emo ends up in jail.
The circle completes itself
Analysis:
Silko relies on Laguna archetypes to bind this novel together. The message of the novel is that union with the earth is necessary for the health of the individual and the role of dualities. Nothing is all bad or all good. This is perhaps best represented by T'seh Montano, look at her name, she is the earth. Only after Tayo has reconciled with her can he find his way back to present.
Meaning: Only through uniting the traditional and modern can society and the individual move forward.
"There are balances and harmonies always shifting, always necessary to maintain." - Betonie explains both the dualities of nature, but also the necessity to incorporate old and new.
"... most people are afraid of change. They think that if their children have the same colored skin, the same colored eyes, that nothing is changing."  - Night Swan explains why the Lagunas reject Tayo, they react to the changes of new America by demonizing all the new. Real change to the traditions and culture is more insidious, in the thoughts of the younger generation, not what they look like.
