The id, ego, and superego are no longer regarded as abstract concepts, but concretely transformed into three independent roles that share the same body (or the same fate line).
In order to increase the dramatic tension, we introduce the "reincarnation" and "mirror" mechanisms. Core metaphor: The human heart is a huge Tower of Babel. The base of the tower is the dark and boiling ego (animal nature), the body of the tower is the crumbling self (human nature), and the top of the tower is the cold and aloof superego (divine nature). The whole book tells the story of how the tower was built, how it collapsed, and how it was rebuilt on the ruins.
Intention: No longer regard the id, ego, and superego as abstract concepts, but concretely as three independent characters who share the same body (or the same fate line).
