One of the Hopi religious societies is the "katsina" society. According to Barry Pritzker, "Reflecting the close association between the world of the living and that of the dead, spirits play an integral role in the land of the living. They are associated with clouds and with benevolent supernatural entities called "katsinam" (the plural of katsina), which inhabit the San Francisco Peaks just north of Flagstaff, Arizona." According to Susanne and Jake Page, the katsinam are "the spirits of all things in the universe, of rocks, stars, animals, plants, and ancestors who have lived good lives."
