What if reality is just a simulation, and we can never know while we're here? What difference does it really make?
Good point, because on one hand, it changes nothing. The best way to live in a simulation is as if you were living in genuine reality, as if every choice were irreversible, being truly present in the moment.
But on the other hand, it changes absolutely everything.
Firstly, if we are the consciousnesses that constructed this simulation and have come to live full lives in this reality, then we have done so for a reason.
To prevent the simulation from breaking, we can never know that reason or purpose while we're here, but it exists, and most importantly - we have decided to come live here fully aware that we will not come to know it.
Whatever that purpose may be, each of us has an unconscious aim to live a life here that fulfills that purpose or at least brings us closer to achieving it.
Perhaps we simply want to live a different life than what we're used to in true reality - Arkhe - or in previous simulated lives. That might offer us perspectives and understanding in a way that even long-term exposure to a foreign culture could never provide.
Perhaps we have a trauma we wish to address, and have therefore chosen a life that will likely bring us closer to discovering ourselves and healing our wounds?
Maybe we have come seeking challenges, things that are undoubtedly familiar only in history books to a civilization capable of creating and maintaining life-like simulations? Or maybe it's just fun and games for us?
Perhaps we are in search of the meaning of life or some other great question, and maybe that is the purpose of the simulation itself? For some reason, the simulation would have been built, with limitless possibilities for it, possibly for commercial or scientific ventures among other reasons.
Secondly, if we have indeed come to live in this reality from elsewhere, then that other place - Arkhe - also exists, even if we cannot know of it here.
It means that after we eventually leave our bodies here, there is a place we return to, and from where we can always come to new lives here. Perhaps we've done so countless times already, and this life here is just one of many we've lived.
In that place are also all the others whom we have encountered in this life. Our deceased relatives and friends, as well as those who leave after us, are there, at least when they're not here or in another simulation.
Thus, we have the possibility to meet them all again, to hear about their lives and share our own. We can exchange experiences and remember shared joys and sorrows through the many lives in which our destinies may have intertwined, even by passing or even as long partnerships.
So, the possibility of living in a simulation doesn't change anything here, but it can change everything that matters to us. It can help us find our purpose, not to mention possibly opening up greater meanings, and it can give us hope that there's something more beyond or outside this life.
But most importantly - it reminds us that consciousness exists here and now. This moment is the only thing that is certainly true for us, and how we use this moment is key to whatever it is we are ultimately seeking.
