This brought to mind other prayers for inner peace, including:
-Saint Francis Xavier Cabrini
PEACE OF HEARTPeace to you all!
Almighty and Eternal God, Give me, I beseech You, the great gift of inward peace. Command the winds and storms of my unruly passions. Subdue, by Your grace, my proneness to love created things too much. Give me a love of suffering for Your sake. make me forbearing and kind to others, that I may avoid quarrels and contentions. And teach me constantly to seek after and to acquire that perfect resignation to Your Holy Will which alone brings interior peace.
