Book excerpt: The Spiritual Exercises of St. Ignatius are perhaps the greatest retreat guide ever written. Neil Vaney's innovative approach to the Exercises is an invitation to a journey of discovery, a challenge to look for Christ in all things and to find him everywhere, even in a grain of sand. Exploring for the first time the unique connection between ecology and the Exercises, Vaney reveals their relevance in our contemporary age. He leads us on an adventure, helping us make the Exercises with our new awareness of the intimate bond between spirituality and the natural world.
