The Rosary is THE weapon.

Do you not see the Madonna always beside the tabernacle?

May the Mother of Jesus and our Mother, always smile on your spirit, obtaining for it, from her Most Holy Son, every heavenly blessing.

Through the study of books one seeks God; by meditation one finds him.

It is true that God's power triumphs over everything, but humble and suffering prayer prevails over God Himself.

In order to console a soul in it's sufferings, point out to it all the good it can still do.

Stop entertaining those vain fears. Remember it is not feeling which constitutes guilt but the consent to such feelings. Only the free will is capable of good or evil. But when the will sighs under the trial of the tempter and does not will what is presented to it, there is not only no fault but there is virtue.
