The disciplines conversation turns to bondage and freedom: technology is a chain when it uses you and a tool when you use it; a thousand unintentional hours can make you an expert in things like auction sites and strangers' life updates; what you are disciplined in mirrors what you actually care about; 'you can't have two masters'; the classic disciplines are deliberately uncomfortable acts against nature; a story about finding your way out of a cornfield by just keeping forward instead of wandering in circles; and the warning not to trade a grimy chain for a shiny one like health or exercise. God's invitation is framed as the only mastery that is actually freedom -- voluntarily following the King, chained by nothing.
