According to George Sword, a ceremony in one of these locations causes a person's life force "to put out of his body all that makes him tired, or all that causes a disease." Raymond A Bucko has described the use of sage and sweetgrass in these locations. A door is opened four times during one of the seven rites of one people that takes place in these locations. That rite is called ‘Inipi’ and in it (15[2])this location is made of sixteen bent (*) willow trees. At an event near Sedona, Arizona improperly organized around one of these places by James Arthur Ray, three people died after overcrowding at one of these locations. These locations usually feature a pit designed to hold hot rocks on which water will be poured. For 10 points name these (-5[1])buildings of the Lakota and other Plains Indians where purification ceremonies take place which cause intense perspiration. (10[1])■END■
