In the weighing of the heart ceremony you must weigh your heart with a feather. If you heart is lighter than the feather you may move on in the journey to afterlife... If it is heavier than the feather you will be faced with the God Osiris and a monster called the Swallower. The Swallower is a deamon that is part lion, alligator and hippo. SCARY! He will eat your heart and the journey to afterlife is over... Wouldn't want that to happen would you?
