O Merciful, Lord, enlighten Thou me with a clear shining inward light, and remove away all darkness from the habitation of my heart. Repress Thou my many wandering thoughts, and break in pieces those temptations which violently assault me. Fight Thou for me, and vanquish the evil beasts; that so peace may be obtained by Thy power, and that Thine abundant praise may resound in Thy holy court, that is, in a pure conscience. Send out Thy light and Thy truth, that they may shine upon the earth; for, until Thou enlighten me, I am but as earth without form and void. Lift Thou up my mind which is pressed down by a load of sins, for no created thing can give full comfort and rest to my desires. Join Thou me to Thyself with an inseparable band of love; for Thou even alone dost satisfy him that loveth Thee—Amen.
Thomas à Kempis.
