aperidomine

Aperi, Domine, os meum ad benedicendum nomen sanctum tuum: munda quoque cor meum ab omnibus vanis, perversis et alienis cogitationibus; intellectum illumina, affectum inflamma, ut digne, attente ac devote hoc Officium recitare valeam, et exaudiri merear ante conspectum divinae Majestatis tue. Per Christum Dominun nostrum. Amen.

Open, O Lord, my lips to bless Thy holy name: cleanse my heart from all vain, foolish, and wandering thoughts; enlighten my understanding, enkindle my affections, and grant that I may recite this Office with devotion, so that I may be heard in the presence of Thy divine Majesty. Through Christ, our Lord. Amen.
