Secret from the Mass of Our Lady of Sorrows, the prayer whispered by the Priest before the Preface of the Mass: 

O Lord Jesus Christ, we offer You prayers and sacrificial gifts, humbly beseeching You that, as we prayerfully recall the piercing of the most sweet soul of Your blessed Mother Mary, so through the merits of Your death and the manifold intercession of her and her holy friends at the foot of the Cross, we may have our reward with the blessed. Who livest and reignest with God the Father, in the unity of the Holy Spirit, one God, world without end. R. Amen

Meditate frequently on the sorrows of the Mother of God sorrows inseparable from those of her beloved Son. If you go to the crucifix, you will there find the Mother, and, on the other hand, wherever the Mother is, there, also, is the Son.
