Prayer for the Power of the Holy Spirit

O Holy Spirit, descend plentifully into my heart. Enlighten the dark corners of this dwelling and scatter there thy cheerful beams.
Breath on me, O Holy Spirit, that my thoughts may all be holy.
Act in me, O Holy Spirit, that my work, too, may be holy.
Draw my heart, O Holy Spirit, that I love but what is holy.
Strengthen me, O Holy Spirit, to defend all that is holy.
Guard me, O Holy Spirit, that I always may be holy.
Amen.
