1941 A.D.

Prayers and Practices
"What a treasure might be gained for the Holy Souls in a single day if we would but choose our vocal prayers from amongst those specially approved by Holy Church and enriched with such great indulgences!
May the prayers here suggested prompt fervent souls to use them for their own benefit, and for the consolation of the Souls in Purgatory.
Prayers
for the departed are more acceptable to God than prayers for the living; for the suffering souls are in the greatest need, and cannot help themselves, yet God is anxious to have them with Him." (Extracted from, "The Poor Souls' Friend",
p. 5, Imprimatur 1941)
