O God, give me light in my heart
And light in my tomb,
And light in my hearing and light in my sight,
And light in my feeling and light in all my body,
And light before me and light behind me,
And light on my right hand and light on my left hand,
And light above me and light beneath me.
O Lord, increase light within me,
And give me light, and illuminate me.
