I will indeed give you concrete instructions about how to pray, but these are merely preparations. The reality takes place only after all thoughts regarding 'methods' are forgotten. Those who enter the prayer life, the life of spirituality, take their life in their hands. How could I seriously tell you prayer and spirituality is about counting repetitions and breathing rhythmically with a prayer formula! Methods have to do with the known, with what we do. The life of prayer and spirituality has to do with the unknown, with the Mystery of God's deifying activity in our lives. The name of this Mystery is Jesus.
