The events of the final renovation are described in the Bundahishn (30.1ff): In the final battle with evil, the yazatas Airyaman and Atar will "melt the metal in the hills and mountains, and it will be upon the earth like a river" (Bundahishn 34.18) but the righteous (i.e. the ashavan) will not be harmed. Eventually, Ahura Mazda will triumph, and his agent Saoshyant will resurrect the dead, whose bodies will be restored to eternal perfection, and whose souls will be cleansed and reunited with God. Time will then end, and asha and immortality will thereafter be everlasting.
