Shudder and Kindle

What is that which shines though me, and strikes upon my heart without hurting it? And I shudder and kindle: shudder, in as much I am unlike it; kindle, in as much as I am like it. It is Wisdom, Wisdom's self which thus shines into me; even breaking through my cloudiness: which yet again overshadows me fainting from it, under the fog and heavy load of mine own punishment.
