From Wakan-Tanka, the Great Mystery, comes all power. It is from Wakan-Tanka that the holy man has wisdom and the power to heal and make holy charms. Man knows that all healing plants are given by Wakan-Tanka, therefore they are holy. So too is the buffalo holy, because it is the gift of Wakan-Tanka.
