Before the Law stands a doorkeeper. A man from the country comes to the doorkeeper and requests admittance to the law. (9.16)
These are the opening lines of the parable that the prison chaplain tells K. in order to teach him about the Law. It's the story of a man who spends his entire life trying to get past the doorkeeper and gain access to the law, a story that eerily matches up with K.'s own struggles.
