Prayer Before Praying the OfficeI don't know if this prayer is old or new, but the Latin is so wonderful that I'm going to quote it in full:
Aperi, Domine, os meum ad benedicendum nomen sanctum tuum; munda cor meum ab omnibus vanis, perversis et alienis, cogitationibus; intellectum illumina, affectum inflamma, ut digne, attente ac devote hoc Officium recitare valeam, et exaudire merear ante conspectum divinae maiestatis tuae. Per Christum Dominum nostrum. Amen.
I've always liked the English as well, but don't have a copy of it on hand. If anyone has it, feel free to put it in the comments box!
