Saint Augustine of Hippo's Prayer to the Holy Spirit

Breathe in 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, then, O Holy Spirit, that I always may be holy. Amen.

A Prayer by Saint Teresa of Avila

O my God! Source of all mercy! I acknowledge Your sovereign power. While recalling the wasted years that are past, I believe that You, Lord, can in an instant turn this loss to gain. Miserable as I am, yet I firmly believe that You can do all things. Please restore to me the time lost, giving me Your grace, both now and in the future, that I may appear before You in "wedding garments." Amen.
