This book assists people to recognize in themselves their capacity for and their skills of leadership, and then to assist them to exercise leadership most effectively in their service of others. This is exactly what the retreat of St. Ignatius, called "Spiritual Exercises," aims to do. The ancient Delphic Oracle used to advise people to "know thyself." And then, "To thine own self be true," is what Polonius tells his son in Shakespeare's play Hamlet. Ignatius assists us to do just that, as we can see in a powerful meditation he offers us midway through the retreat. It is entitled, "Two Types of People" people who march under two banners with absolutely opposite messages on them. One banner says, "What's in it for me-me-me?" and the other banner says, "And what can I do for you?" In his retreat, Ignatius is guiding people through the "conversion" which he himself experienced.
