A prison is a place where a person is remanded as punishment for not following society's rules. It is a penitentiary where its members are not allowed to advance until they are fully penitent. These penal institutions are not just brick-and-mortar buildings, they are also invisible, energetic, idea-institutions, which have been built on every corner and into the very fabric of the society of mind. You must bow on your knees at all times before the ruling-class norms to show you are submissive. The penalty for not obeying, or being a submissive spirit to the ruling-class authority is applied in these invisible penal institutions. The penalty for not playing along is you will be socially-jailed from moving up the ladder, financially penalized, or whatever measure of control is necessary, commensurate with your defiance and disloyalty.
