O God, with whom is the well of life, and in whose light we see light, increase in us, we beseech Thee, the brightness of divine knowledge, whereby we may be able to reach Thy plenteous fountain; impart to our thirsting souls the draught of life, and restore to our darkened minds the light from heaven; through Jesus Christ our Lord. Amen.
