After completing reading parts of a work, I finally understand the “alternate world” the protagonist wandered into.
It is a never ending world, essentially a loop, one can say. The artifacts — remains of the past stayed there. Conversations between the protagonist and the related characters took place in the alternate world, which were centered on things that one couldn’t let go easily. Things that were precious to the protagonist, as if they were a source of reliance when the protagonist escapes to the alternate world.
At a latter part of the said work, the protagonist was presented an ultimatum — either to abandon the alternate world and move forward, or to remain in the alternate world and circle endlessly. He chose to move forward, and as a result, dependencies between the alternate world and the reality began to collapse. Whether the event occurred is a good thing, it was up to the reader, I assumed.
Essentially, it boiled down to this.
Rather than clinging to the past, accepting it and moving forward is the way going forward if one wishes to progress. However, easier is said than done. I caught myself into this dilemma which lasted for a long period of time. Crawling out of it isn’t easy, admittedly, but it did provided me a fresh, new perspective of a certain matter.
