For Enlightenment

We beseech Thee, O Lord, let our hearts be graciously enlightened by Thy
holy radiance, that we may serve Thee without fear in holiness and
righteousness all the days of our life; that so we may escape the
darkness of this world, and by Thy guidance attain the land of eternal
brightness; through Thy mercy, O blessed Lord, who dost live and govern
all things, world without end. Amen.
