Dan Burke breaks down St. Teresa Avila’s timeless classic, “The Interior Castle,” that explains the seven levels of progress in the spiritual life from a doctor of the church. He highlights the specific patterns the Evil One employs at the various stages of growing closer to God. Burke, a prolific author, is the founder and president of the Avila Institute for Spiritual Formation, which offers graduate and personal enrichment studies in spiritual theology to priests, deacons, religious and laity in 90 countries and prepares men for seminary in more than 30 dioceses.
