Theory

The passion which begins the ego cycle of the E1 character is the passion of Anger and the fixation which supports this passion is Perfectionism. When we first think of anger and a character enveloped by the expression of anger as a fundament of their psyche it is easy to create a mental image of a person with a short fuse, one who is in a state of rage all the time. This image has some accuracy to it, but can also be misleading. Anger in the E1 is not conscious, as all of the passions are unconscious, and instead its existence is more so suggested. These are characters who instead control their anger in order to uphold an image of being well-behaved and benevolent.

Rather than the image of anger simply as an emotional reaction to danger or misfortune, anger is the energy the personality feels when facing the existential void created out of their fall from fullness. Because it is their neurotic way of trying to achieve a state of higher existence, they face everything in reality with a subtle anger like a fiery engine that drives them towards action; we may use the metaphor of "the wrath of God" to paint the picture of a being who believes himself perfect and exacts his righteous judgment on other people. Ichazo notes this passion as "standing against reality" and it entails a dissatisfaction with the way reality fundamentally is. This comes from a projection of their own brokenness, by recognizing that they have fallen they recognize it as a mistake needing to be repaired.

Perfectionism then ensues as the fixation which supports anger. The motivating energy of anger creates a notion of "pushing the river" in the E1, that is, the natural flow of reality is not enough and is fundamentally "incorrect," and through perfectionism they attempt to shape it into an exact image of what they think it should be, not realizing that pushing a river is useless; reality will flow the way it should on its own.
