Greed and hatred are the prime manifestations of the ego process. To the extent that grasping and rejecting are present in the mind, mindfulness will have a very rough time. The results of this are easy to see. If you sit down to meditate while you are in the grip of some strong obsessive attachment, you will find that you will get nowhere. If you are all hung up in your latest scheme to make more money, you probably will spend most of your meditation period doing nothing but thinking about it. If you are in a black fury over some recent insult, that will occupy your mind just as fully.
