Ancestors are believed to have reached a better world from which they can influence life on earth. They can help or punish their descendants depending on their behavior. Ancestors are also the judges that have the power to allow a descendant to enter the "pantheon of the ancestors". If an ancestor chooses to deny entrance, the soul of the disavowed one is condemned to run at random for all eternity. Because of these beliefs, Mossi swear by their ancestors or by the land; when they do so (which only occurs in extreme situations), it is more than symbolic — it is a call to imminent justice.
