Prayer of Consecration to the Immaculate Heart of Mary:

O Immaculate Heart of Mary, Queen of heaven and earth, and tender Mother of humanity, in accordance with Your ardent wish made known at Fatima, I consecrate to You myself, my brothers and sisters, my country, and the whole human race.

Reign over us and teach us how to make the Heart of Jesus reign and triumph in us and around us, as It has reigned and triumphed in You.

Reign over us, dearest Mother, that we may be Yours in prosperity and adversity, in joy and in sorrow, in health and in sickness, in life and in death.

O most compassionate Heart of Mary, Queen of Virgins, watch over our minds and hearts and preserve them from the deluge of impurity which You lamented so sorrowfully at Fatima. We want to be pure like You. We want to atone for the many sins committed against Jesus and You. We want to call down upon our country and the whole world the peace of God in justice and charity.

Therefore, we now promise to imitate Your virtues by the practice of a Christian life without regard to human respect. We resolve to receive Holy Communion on the First Saturday of every month and to offer You five decades of the Rosary each day, together with our sacrifices, in a spirit of reparation and penance.

Amen.

This prayer reflects a commitment to follow the example of Mary's virtues, especially her purity, humility, and dedication to God's will. It also echoes the requests made by Mary during her apparitions at Fatima, emphasizing repentance, prayer, and reparation for sins.
