“In the western tradition, revelation has generally been interpreted as the communication to human beings of a divine plan, the release of new information and insights when the deith has perceived that mankind has reached the fullness of time and can now understand additional knowledge about the ultimate nature of the world. Thus, what has been the manifestation of deity in a particular local situation is mistaken for a truth applicable to all times and places, a truth so powerful that it must be impressed upon peoples who have no connection to the event or to the cultural complex in which it originally made sense. The recounting of the event becomes its major value and both metaphysics and ethics are believed to be contained in the description of the event. Ultimately the religion becomes a matter of imposing the ethical perspective derived from reprocessing the religious experience on foreign cultures and not in following whatever moral dictates might  have been gleaned from the experience.

            The question that the so-called world religions have not satisfactorily resolved is whether or not religious experience can be distilled from its original cultural context and become an abstract principle that is applicable to all peoples in different places and at different times. The persistent emergence of religious movements and the zeal with which they are pursued would seem to suggest that cultural context, time, and place are the major elements of revelation and the content is illusory. If not illusory, it is subject to so many cultural qualifications that it is not suitable for transmission to other societies without doing severe damage to both the message of revelation and the society which receives it.

            American Indians and other tribal peoples did not take this path in interpreting revelations and religious experiences. The structure of their religious traditions is taken directly from the world around them, from their relationships with other forms of life. Context is therefore all-important for both practice and the understanding of reality. The places where revelations were experienced were remembered and set aside as locations where, through rituals and ceremonials, the people could once again communicate with the spirits. Thousands of years of occupancy on their lands taught tribal peoples the sacred landscapes for which they were responsible and gradually the structure of ceremonial reality became clear. It was not what people believed to be true that was important but what they experienced as true. Hence revelation was seen as a continuous process of adjustment to the natural surroundings and not as a specific message valid for all times and places.

            The vast majority of Indian tribal religious, therefore, have a sacred center at a particular place, be it a river, a mountain, a plateau, valley, or other natural feature. This center enables the people to look out along the four dimensions and locate their land, and to accept responsibility for it. Regardless of what subsequently happens to the people, the sacred lands remain as permanent fixtures in their cultural or religious understanding. Thus, many tribes now living in Oklahoma, but formerly from the eastern United States, still hold in their hearts the sacred locations of their history, and small groups travel to obscure locations in secret to continue tribal ceremonial life.” 65-66
