The original text for this spiritual practice occurs in Ignatius’s Spiritual Exercises.  Fr. Gallagher’s approach is to provide a careful explanation of it that is integrated with the experiences of a wide variety of people who try to practice it in their daily lives.  His profound understanding of the Ignatian principles themselves, combined with his thoughtful observations about the problems that individuals tend to encounter in their use, make for a wonderfully insightful and practical book that will make good reading for priests, retreat directors, those offering spiritual direction, and for anyone who is eager for a greater awareness of God’s action within one’s daily spiritual life.
