Oh, let's discuss greed for a bit, shall we? We can do envy later, for that is a topic I would like to explore. We can do the whole lot later if it seems interesting. If it means anything.
What is greed, first of all, and the need to own? The empty self is at odds with itself. It doesn't really need things, it doesn't need much money to live, but it is the self, and selfish.
I'd propose that greed is like a cat. It lingers near the door. It makes noise. Unsatisfied in itself, it howls, not knowing the useless noise it makes.
