This rosary consists of four decades (40 beads) in memory of the forty hours which Our Lord is thought to have spent in Limbo. There are also the 5 introductory beads as on the Dominican Rosary.
One begins and ends this chaplet with the De profundis (Psalm 130) or an Our Father and Hail Mary:
De Profundis Out of the depths I have cried to Thee, O Lord; Lord, hear my voice.
Let thine ears be attentive to the voice of my supplication.
If Thou, O Lord, shalt observe iniquities; Lord, who shall endure it?
For with Thee there is merciful forgiveness:
and by reason of Thy law, I have waited for Thee, O Lord.
My soul hath relied on His word; my soul hath hoped in the Lord.
From the morning watch even until night, let Israel hope in the Lord.
Because with the Lord there is mercy, and with Him plentiful redemption.
And He shall redeem Israel from all her iniquities.
On the large beads is made acts of faith, hope and charity. On each small bead is said: Sweet Heart of Mary, be my salvation. Each decade is concluded with:
V. Eternal rest grant unto him/her, O Lord.
R. And let perpetual light shine upon him/her.
V. May he/she rest in peace.
V. May his/her soul and the souls of all the faithful departed, through the mercy of God, rest in peace.
And after the final decade:
All make the sign of the Cross.
V: May the love of God and the peace of the Lord Jesus Christ bless us
and console us and gently wipe every tear from our eyes: in the name
of the Father, and of the Son, and of the Holy Spirit.
