Book Three, Chapter 34
That He That Loves God Relishes Him Above All Things and in All Things

O Light perpetual! transcending all created lights, dart forth that light from above, which may penetrate all the secret recesses of my heart.  Cleanse, cheer, enlighten, and enliven my spirit with its powers, that with joyful ecstasy it may cleave to You.  Oh, when will this blessed and desirable hour come, that You may fill me with Your presence, and become to me all in all?  So long as this is not granted, my joy will not be full.
