Something profound I saw on the even*cleveland blog a while back:
…the fact that we can never know light itself is helpful in appreciating the working of boundless compassion. When the light of compassion illuminates our existence, it reveals our self-delusions. Hiroyuki Itsuki … describes this as follows:
We cannot know that we are illuminated by a great light simply by looking up into the sky. But if we lower our heads and look down at our feet we can clearly see the long, dark shadow that stretches out from us. We know that the darker and blacker that shadow is, the brighter the light that shines upon us.
