In this chapter, we learn that the enemy of spiritual bodies is the "sunshine realm weibo" , which means "the realm of light" . In other words, it's not just the dark side of the universe that we're dealing with here. It's also the light side, which we'll get to later in the chapter. We're also introduced to the concept of the "heaven eye" and the "earth eye," which is a fancy way of saying "the darkness of the soul." The dark side is the one that's afraid of the light. The light side is afraid of darkness because the darkness is the source of all things, including the light itself. The darkness is also afraid of heaven because the light is a source of everything, including all things. So, the darkness isn't afraid of anything, it just fears the darkness itself.
