             The symbol door, can be interpreted as a passage. Not only a passage from one place to another, but also a passage from one stage of life to another. For example, when Hester leaves the prison door to go start a new life she is going to a new stage in her life. She is going from the familiar and known to the unfamiliar and perhaps scary world outside the prison walls. When she walks through that door, her life changes, she is no longer the same young women that she use to be. Hester is now on her own, alone in the world with a child, and a Scarlet letter on her chest telling the world what she has done and the sin that she has committed.
