Totalitarian regimes govern by instituting organizations along the lines of the ideological reality they are trying to create.
The creation of that reality is, in fact, a profoundly creative impulse. It seeks to answer a deeply atavistic call in both the totalitarian program’s leadership and followership.
To try to create a brand new reality is to try to imitate God in His creative guise. When the totalitarian leader is ready to govern he does so not by the use of terror and propaganda but by the institution of organizations that have as their essential mandate the realization of the leader's totalitarian vision.
"Organization and propaganda (rather than terror and propaganda) are two sides of the same coin." (The Origins of Totalitarianism, Hannah Arendt, 1994; page 364).
