Karl Rahner said that the rules of discernment of spirits, contained in the exercises of St. Ignatius of Loyola, provided a practical, simple and systematic method for discovering the will of God for each person.

In this book, Father Timothy Gallagher offers a clear, lucid and empirical reading of the first set of rules, in order to facilitate its application in daily life. In this way, it fulfills the deep desire of St. Ignatius: that Christians of any origin can develop the capacity to understand and respond to the spiritual movements that arise daily in their hearts.

This book will be very useful both for those who provide spiritual guidance and for those who receive it and, in general, for all those who wish to reach a deeper understanding of Ignacio's rules of discernment in order to apply them continuously in his life spiritual.
