On the Exercises of Piety by Jean Guibert (1857 - 1914)

In this book, Father Jean Guibert of the Society of St. Sulpice shows how piety permeates the spiritual life in mental and vocal prayer, in the sacraments, in various devotions, in spiritual reading, in the examination of one's conscience, and in spiritual retreats. This book is the sequel to Father Guibert's On Piety, wherein he explains the nature of piety and its effects. Both books bear an imprimatur. (Summary by dave7)
