Greed simply means you are feeling a deep emptiness and you want to fill it with anything possible; it doesnt matter what it is. And once you understand it, then you have nothing to do with greed. You have something to do with your coming into communion with the whole so the inner emptiness disappears. And with it, all greed disappears. That does not mean that you start living naked; that simply means you do not live just to collect things.
