"Carmel teaches the Church how to pray."- Pope Benedict XVI
What makes Carmelite prayer distinctive is not the prayer itself--in fact, there is no 'method' for Carmelite prayer -- it is all about the time and energy that is actually put into prayer.
During the canonization of Saint Nuno Alvares (April, 2009) Pope Benedict said, "Carmel teaches the Church how to pray." That's what Carmel has always been about: prayer. And that's what being a Carmelite - whether friar, nun, or Lay Carmelite - is all about: prayer. It's not method; it's emphasis.
