Written by S. Alphonsus Rodriquez for religious but a great 3 volume set for anyone to read.

Its a really good book, but it was not written by St. Alphonsus Rodriguez, but by Fr. Alonso Rodriguez S.J. A priest who was a novice master in a Jesuit house of novices. Many religious orders used this manual of astetics to train their novices; Msgr. Lefebvre mentions that he and the other Holy Ghost novices read the book.
