May the guiding hands of God be on my shoulders,
may the presence of the Holy Spirit be on my head,
may the sign of Christ be on my forehead,
may the voice of the Holy Spirit be in my ears,
may the smell of the Holy Spirit be in my nose,
may the sight of the company of heaven be in my eyes,
may the speech of the company of heaven be in my mouth,
may the work of the church of God be in my hands,
may the serving of God and my neighbor be in my feet,
may God make my heart his home,
and may I belong to God, my Father, completely.

Original in old Irish:
Robé mainrechta Dé forsind [f]ormna-sa,
robé torruma in spirta naoimh for in cend-sa,
robé airde Críst isin édan-sa,
robé ésdecht in spirta náimh isna clúasaib-sea,
robé bolltanugad in spirta nóib isna srónaib-sea,
robé imfaiccsin fer nime isna súilib-sea,
robé comlabra fer nime isna bélaib-sea,
robé lubair eculsa Dé isna lámaib-sea,
robé les Dé ocus a choimnesa isna cosaib-sea,
roba locc do Día in cride-sea,
rob la Día athair uile in duine-sea!
Credo ocus pater.
