The world envisaged by the Tulsa sage was about like this: The middle earth which mankind knows, is flat and square and lies afloat upon “the wide white waters.” There is a world above it and a world below it, and these are inhabited by beings like ourselves. Below are those left behind when the races now on earth found their way to its surface; above, those who had lived on earth but, having undergone the experience called death, had traveled westward, crossed a narrow point in the ocean stream, upon a foot log, and either remained with the malevolent spirits in that quarter or ascended to the fortunate region directly overhead, presided over by Hisakita-imisi, “the breath holder.” The white streak in the sky which we call “the milky way” was said to be the very road which they traversed. Unavenged souls of those who had been killed in wars, however, were unwilling to begin their journey until scalps from the offending tribe were brought in, and meanwhile they remained about the eaves of the houses, moaning. Some said that bad spirits were reincarnated into beasts, but about this men differed. However, they were agreed that human beings might acquire such malevolent power as to become witches and assume the forms of animals while still living on earth. Their evil dispositions were attributed to lizards who had taken up their abode inside of the witch, but might be expelled by the proper medical rites.
