The basic constituents of ego are of three simple types: one is passion, the second one is aggression, and the third one is ignorance. Passion means trying to suck things in, to collect things for yourself. Aggression means pushing out or exorcising anything that goes against your particular scheme. Ignorance means ignoring anything that comes up and puts you on the spot, because it is too embarrassing to look into it.
