Light is knowledge; darkness is ignorance

I am re-reading spiritual books I have read many times in the past. What fascinates me is that I feel as if I am reading them for the first time. As I grow spiritually, I am opening up to more and more light. Light is knowledge. The opposite - darkness is ignorance.

As more spiritual light pours in, I am being exposed to more spiritual knowledge. I understand concepts that would have baffled me, even last year. I love this inpouring of knowledge. However, I'm aware that I am only scratching the surface of the knowledge that is God.
