Holy Mary, Mother of God, preserve in me the heart of a child, pure and clean like spring water;
a simple heart that does not remain absorbed in its own sadness;
a loving heart that freely gives with compassion;
a faithful and generous heart that neither forgets good nor feels bitterness for any evil.
Give me a sweet and humble heart that loves without asking to be loved in return, happy to lose itself in the heart of others, sacrificing itself in front of your Divine Son;
a great and unconquerable heart which no ingratitude can close and no indifference can tire;
a heart [aching for] the glory of Christ, pierced by His love with a wound that will not heal until heaven.
