Past and Future
The now is all that we have, (some people say) but the excellence of theme park earth is that the past and the future are just as fluid as the now. The past and future are cognitive constructions that become the lattice, the framework for what we are in the now. There's a perspective that past events are immutable and unchangable, in other words they happened, and cannot unhappen. The meaning we assign to events, the beliefs we form can seem to have a similar solidity, because x happened I know y is true. The x and y relationship is just a first draft, z could also be true. If y is a belief that makes life less than wonderful, then y is false. Because the point of theme park Earth is play, and beliefs that stifle, constrain or negate play are out of sync with being in physicality.
The future is also a construct that constrains or enables playfulness, eg Theme Park literacy. The past and future are real because they are cognitive structures, perceptual scaffolds that we deploy around the now, and the now is pure perception.
