Looking deeply into what we crave is a deep practice. The fish sees a beautiful bait, but does not know that inside the bait there is a hook. The fish just swallows the bait, gets caught and pulled out of the water. We behave like the fish. We become the victims of such craving, and suffer a lot. Yet we continue the course of running after these objects of craving. When you can see deeply into the nature of craving, you get free.
