The Soul of the Apostolate
This book is in Portuguese.
The Abbot of Sept-Fons on the interior life as the soul of all apostolic works: God wills works and the interior life, their union, the danger of action without it, the fertility of works through it, then principles and counsels (mental prayer, the liturgical life, custody of the heart, devotion to Mary). Grown from a 1907 pamphlet into the 1912 book and enlarged ever after; French text of the Sept-Fons edition (Lyon, Vitte, 1927), from a poor OCR whose accents were restored by machine. See also the condensed 1918 English version by Girardey.
