Ego

We are aware that there are several definitions for ego. Skinner has one, Freud has another, Jung another, all conflicting. DDHG! Harold is using the yogic tradition that the ego is the part of us that should be lost or shed because the true self must be single (whole) in order to say "I am". If the "self" that runs up charges on the credit cards is not the "self" that pays the bills, then you know there is something wrong and the ego is indeed present.

Also, the ego is associated with vanity or hubris. If you are easily embarrassed or easily humiliated, or devastated if someone walks into the bathroom when you're there (accidents happen) then you're not being real.
Another definition of the self is "what works" and the ego "what doesn't work". In other words, the real self is effective and integrated.
Harold defines the ego as all that is part of us that we might think is us, but is not. Harold defines the part of one's self that says, "I am" as "The Self". Harold uses ego to oppose "The Self", as fantasy is opposed to imagination or the demi-urge opposed to god/dess.
A complex (i.e.habit) is not you, it is a complex that has begun a life of it's own so become "ego" and needs to be distilled out.
Ego is motivated by "Skinner Box Behavior"(i.e. programming and parent tapes).
Another way to look at this is to trace the beginning of LIE/DENIAL to the beginning of the ego and the end of true sanity and true self.
As that part of ourselves that is free from the autonomous unconscious complexes (the shards of other peoples' soul or spirits).

After these parts are integrated or separated out (distilled), then the things are in agreement (i.e. there is no difference between who makes the charges and who pays the bills). When the true-conscious self is found, it can unite with the true unconscious self and produce the lesser superconscious.

Then comes the union of Hadit and Nuit and the greater superconscious.
