Certain portions of Sacred Scripture, attentively pronounced or reverently considered, are similarly of great efficacy.  Consequently, we should be familiar with those facts corresponding to the virtue in question (virtue concentrated upon), and employ them frequently, particularly when beset by the predominant opposite passion.  Those, for instance, who’s strive to attain mildness and patience may repeat these or similar passages: 

“Bear patiently with the wrath of God which comes upon you in punishment for your sins.”  –Baruch 4:25

“The patience of the poor shall not perish, or be deprived of its reward”.  –Psalm 9:19

“The patient man is better than the valiant; and he that ruleth his spirit, than he taketh cities.”  –Proverbs 16:32

“By your patience you will win your soul.”  –Luke 12:1

“With patience run to the fight set before us”.  –Hebrews 12:1

Those or similar aspirations may be used: “O God, when shall I be armed with patience as a shield against the weapons of my enemy?  When shall I so love Thee as to receive with joy all the afflictions Thou shalt be pleased to send?  O life of my soul, shall I never begin to live for Thy glory alone, perfectly resigned to all sufferings?  O how happy, I should be, if in the fiery trial of tribulation, I burn with a desire of being consumed for Thy service”.
