For more about Dine’ ceremonies, I recommend the previously mentioned Molded In the Image of Changing Woman, by Maureen Trudell Schwarz.
There is a lot of false information about shamans available. For information that is based on research, I recommend looking up the topic in any of a number of books about the anthropological study of religion.
For more information about rituals and religious beliefs of the Puebloan peoples, I recommend The Tewa World: Space, Time Being and Becoming in a Pueblo Society, by Alfonso Ortiz.
Ella Deloria’s Waterlily contains much information about religious rituals, including the Sun Dance and Ghost Bundle.
