The month of Elul is meant to be a time of introspection. We are to view this period of time as a time of renewal. We are able to clean our slate and be offered a new beginning.
The symbolism of this idea is a group of men in prison. They dig a tunnel to get. This whole group of people escape the prison except for one person. He goes back to his cell and to his prison life. To his surprise, he gets beaten by the guard. He tells him that he’s a fool for not taking advantage of his opportunity to leave.
This is Elul. We are given an opportunity for forgiveness and closeness. We should not miss out and we should do the right thing.
