"The two forms basic to American Indian literature are the ceremony and the myth. The ceremony is the ritual enactment of a specialized perception of a cosmic relationship, while the myth is a prose record of that relationship. [...] The formal structure of a ceremony is as holistic as the universe it purports to reflect and respond to, for the ceremony contains other forms such as incantation, song (dance), and prayer, and it is itself the central mode of literary expression from which all allied songs and stories derive. The view all the ceremonies as related to one another in various explicit and implicit ways, as though each were one face of a multifaceted prism. [...] The purpose of a ceremony is to integrate: to fuse the individual with his or her fellows, the community of people with that of the other kingdoms, and this larger communal group with the worlds beyond this one. A raising or expansion of individual consciousness naturally accompanies this process. The person sheds the isolated, individual personality and is restored to conscious harmony with the universe. In addition to this general purpose, each ceremony has its own specific purpose. This purpose usually varies from tribe to tribe and may be culture-specific."
