See Ignatian Spirituality for more about the Spiritual Exercises
Ignatius of Loyola wrote the Spiritual Exercises once he had found that certain meditations and contemplations–“Exercises”–were helpful to others in coming to a clearer image of God, themselves and their place in the world. While the text is widely published, the Exercises are a more a set of “director’s notes” used to guide a person during a month-long retreat than a text to be read alone. The ‘weeks’ described in the Exercises refer to the four main phases.
Every Jesuit does the Spiritual Exercises during his initial training and again during Tertianship. Please pray for the Tertians in Dublin who will be doing the exercises from 19 November to 20 December.
