Clark Wissler The Sun Dance of the Blackfoot Indians

Thus, we have a custom of calling upon the sun in time of need which is an almost universal practice, a more restricted form of such appeal peculiar to women in so far that sexual morality is a necessary qualification, the more specific vow of "going forward to the tongues", and the exceptional vow to perform the medicine woman's functions at the sun dance, a fair illustration of the way in which most complex folk ceremonies are supported by a pyramid of less and less differentiated practices.

In the first place, a sun dance cannot occur unless some woman qualifies for the office. On the other hand, it was almost inconceivable that there should be a summer in which such a qualification would not be made. This attitude of our informants implies that public opinion had sufficient force to call out volunteers against their own wills. There was a feeling that an annual sun dance was, from a religious and ethical point of view, necessary to the general welfare, for which some individual ought to sacrifice personal comfort and property to the extent required by custom.

From two to five persons undergo this torture every Sun-Dance. Its object is military and religious. It admits the young man into the noble band of warriors, whereby he gains the esteem of his fellows, and opens up the path to fortune and fame. But it is chiefly a religious rite. In a time of sickness, or danger, or in starting upon some dangerous expedition, the young man prays to Natos for help, and promises to give himself to Natos if his prayers are answered. Upon his return, when the Annual Sun-Dance is held, he fulfills his vow, gives himself to his god, and thus performs a twofold duty.
