I think that on Dante’s journey through Hell he learned that there is more to Hell then just fire and bad people. There is an order to it and a system in how everything works there. The nine levels of hell categorize the people that end up there. On a more spiritual level he learned just how much every action you make in your life will affect you in the afterlife.
While reading about the journey I learned about the different levels of Hell, so I would say Dante’s learning and mine were similar. I always just thought of Hell as an unpleasant place where people committed the worst sins went after they died. Before the reading I hadn’t really thought about what would qualify as a “bad enough’ sin to get you sent to Hell. It brought up the question to me, “Does Heaven work the same way?’
