mark is...Open, O Lord, my mouth to bless your holy name; cleanse my heart from all vain, evil, and wandering thoughts; enlighten my understanding and kindle my affections; that I may worthily, attentively, and devoutly say this Office, and so deserve to be heard before the presence of your divine Majesty. Through Christ our Lord. Amen.Lord, in union with that divine intention, with which you praised God while you were on earth, I offer to you this Hour.
