Differences, contrast, they are the very things to separate suffering from bliss. It is a fantabulous demonstration about deconstructionism.

If the real world becomes perfect, fitting in all the dreams once described by human being, it wouldn’t satisfy people. In other words, a world can not be a blissful place in itself, because bliss is less an outside reality than an estimate of the inner reality, a subjective judgment, a mental state.

So when there’s nothing bothering people, they would for sure have impulses to create a troubled world to experience as a counterpart to make them believe that they are leading a life deserving to be appreciated and grateful.

In the end of the film, the hero chose to live in a horrible world not for the sake of suffering but of the happiness from being cared and loved by his fake daughter which is constantly strengthened by the drastic contrast of a simultaneous existing evil environment. It reminds us that not only the comparison of the opposite feelings is the foundation of forming a feeling of bliss, but also the tight entanglement of them can make the bliss much more blissful.

Just record some inspired dialogues:

The world is but lights bouncing around your neurons. It is a metaphor about the subjectivity of the world, the affirmation of the inner reality.

The talking about the hell , about the people in hell pretending to be suffering.

The metaphor about the tortoises piling up endlessly .
