What took place for the individual in time of sickness happened for the entire tribe annually at the time of the poskita. It had been given to men by Hisakita-imisi for their health and for the annual renewal of the life of the tribe, as well as the individual lives of those composing it. The square-ground fire was but a detached fragment of the sun, the sky fire, and both of these meant life, for both were necessary to the lives of men. The renewal of the fire was the renewal of life, an act by means of which, the connection between human lives and the life of the universe was restored, and the corruption, which had accumulated about the fire obtained the previous year, gotten rid of. Similarly the participants were cleansed internally by means of the poskita medicines, one of which was to make good the defects of the system and heal its diseases, the other to insure the enjoyment of positive benefits. Hence it was that a little of each was carried home by every household and hung up by the door, some of it being used occasionally in medicines until the next annual ceremony.
