"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 Lakota 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. This interlocking of the basic forms has led to much confusion among non-Indian collectors and commentators, and this complexity makes all simplistic treatments of American Indian literature more confusing than helpful. Indeed, the non-Indian tendency to separate things from one another—be they literary forms, species, or persons—causes a great deal of unnecessary difficulty with and misinterpretation of American Indian life and culture. It is reasonable, from an Indian point of view, that all literary forms should be interrelated, given the basic idea of the unity and relatedness of all the phenomena of life. Separation of parts into this or that category is not agreeable to American Indians, and the attempt to separate essentially unified phenomena results in distortion."
