Reason why analogical characters are used in everyman?

I personally do not know what you're asking here?

Could you clarify a little more?

One of the main reasons that make the play so open, and associate to the reader or the spectator is that aspect of analogy. We can establish a kind of relationship between our own life and Everyman's life. As you will see, the author wants us to make that comparason. Have you noticed that the caracters are allegorical? That is how things should be done so that every body "everyman" finds himself in the plays.

Hope "it go helep you"
