Hmm, nice question, i dont knowe it either XD, ill edit with the news
EDIT: ok, so te book says:
THE BEGINNING: Each journey gives rise to the chance encounters, and each encounter brings forth a farewell. When a farewell leads to a journey, the worlds open their heart. Those chosen by the light or ensnared by darkness. Friends who share the same bonds, though their paths may differ. When you doubt the path trod thus far, when the hand you held is lost to you, gaze anew at the heart that once was... for all the asnwers are within.
INTERLUDE: A long dream. A sad farewell, hanging in the air in the ¨world between¨. What is reality? What is Illusion? The path chosen by the young boy leads to his memories. When caught in the stream of the days and nights going past gaze anew at your steps... for the all confusion will end.
THE FUTURE STORY: Will the day come when this battle, born of confusion, will end? It is different things to different people. Can the reality be that which is hidden? The reason is more existence. Still, memories can be believed. Be not afraid. Entrust your body to the soothing waves of your memories. By and by, your fleeting rest will be over... and everything will begin
Of course!..... wait, no, I dont get it XD.
Lets see, this may mean sora´s story, BBS, or/and 358:
beginnig : journeys give rise blah blah blah, worls open their heart, those chosen by light (sora) or ensnared by darkness (riku), blah blah, for all the answer are within, makes sense. Then it says a long dream in the world between or CO, reality or memories, and illusion and those fake memories, path to CO chosen by sora, all the confusion will end(wake up), also makes sense. Battle born of confusion will end, defeat org, memories back, then i dont understand the rest, thats where it makes no sense to me. it can mean that the story is not about sora, but VAT, thats why it says and everything will begin or thats 358 meaning confusion as not remembering (still, memories can be believed) , battle by escpaing the org, different things to different people, means different opinions in the org, then, sora wakes up and ''everything will begin''
