One of the most beautiful prayers to the Holy Spirit attributed to St. Augustine
Breathe in me,
O Holy Spirit,
so that all my thoughts
can be holy.
Acted on me,
O Holy Spirit,
so that my work
also be holy.
Draw near my heart,
O Holy Spirit,
so that I only love
whatever is holy.
Strengthen me,
O Holy Spirit,
for me to defend
whatever is holy.
Take heed to me,
O Holy Spirit,
so that I always
can be holy.
Amen.
Prayer given to St. Augustine of Hippo
