The Source Of All Things has always existed. Your reality has not. From infancy through early childhood, you developed a consciousness, began to form memories, and your sense of self started to manifest and develop. Everything you have experienced from that point onward is your reality. All the experiences you have ever had, all your thoughts, all your actions, and how you interact with everything you experience, this is your reality.
So what happens when you die? Simple: your reality ceases to exist. There will never be another one like it. That dimension of the universe just poof, there one moment, and gone the next. But the Source from whence you came is timeless, and will always exist. Its creation expands outward ceaselessly. The universe, and creation, continues infinitely, even without your consciousness being around to experience it.
Your reality is a such a microscopic speck in time as we know it. Your planet has been around far longer than our species, but even your Earth is so fresh in the timeline of all existence, it is impossible to fully comprehend how incredibly brief the age of all organic life here on this planet will be in the ultimate scope of time itself. Its reign will be less than a flash fire in a frying pan, a nanosecond, a single cycle of a CPU.
And here you are. A human being, 2020 years after humanity's common era, reading an anonymous posting on a global communication network, the likes of which couldn't be fathomed a century ago. This is your time. This is your moment. How will you choose to exist in your reality? How will you shape your existence, knowing that this is your one opportunity to experience reality? Will you choose to fight for your happiness, or will you roll over idly and fritter your existence away until it ceases to be?
The choice is yours.
This some Schitzophrenia-level failed-the-fuck-out-of-middle-school-biology shit right here.
