Between death and our judgment, there is a time of waiting and payment for the things we did in life. We will wait in one of two places, which God calls Paradise and Prison. This is also the time when those who disobeyed God's laws and chose not to repent of their disobedience will pay for their sins.
Paradise is the place where those who accepted and tried to follow the Plan will go after death. It has also been called a place of rest from the trials of mortal life. Many people in Paradise will be given the task of teaching about the Plan to those in Prison.
Prison is the place for those who either did not accept the Plan or did not choose to follow it or for those who simply didn't ever learn about the Plan. Those in Prison will be taught God’s Plan and will have the opportunity to accept it. God has promised that everyone will understand the Plan and choose to accept or reject it before their lives are judged. Those in Prison who accept the Plan will be able to enter Paradise and have the rest that can be found there.
The ‘8’ symbolizes the two places of waiting called Paradise and Prison. It also symbolizes that the two places are connected and people can move between them under certain conditions. It further symbolizes two connected albeit closed circles because further progress is only possible after judgment.
