In this homily on the healing/exorcism of the lunatic (St. Matthew 17:14-23), after talking about the life skill of monitoring the response to and use of compliments and criticism, Fr. Anthony continues his metaphor of the mind as terrain that has considerable ungoverned territory.  The prayer and fasting that Christ says is required for advanced exorcism help to increase faith by developing the believer's capacity for (neptic) graceful single-mindedness.  This allows the believer to ignore the orcs spewing out of the Mordor of his mind until such time as he has the faith to level Mount Doom (or move it into the sea).  Enjoy the show!
