Quote:Zezekuta of the carpenters has shown you the mask you are to wear in the purification rite, explaining that the woodsin which clings to a soul is transferred to the mask by the power and magic of the dances. He warns of the danger of a mask breaking should the woodsin be too great for it to bear.
