Emily Dickinson's poem "Because I Could Not Stop For Death" talks about life and death. The speaker 'narrates' how she was visited by "Death" and taken to her grave on a "carriage". The main topic or idea of the whole poem is that of man's immortality, the interpretation of death and life after death. The speaker delves into the interpretation of immortality from the standpoint of a mortal.
