Something very pristine lies in the great beyond & it tells me to be at peace with myself and the happenings of this world.
It's like playing a video game where once you screw up you can play again; similarly if in this life you screwed up so you think of the great beyond/ an afterlife as an escape from this one.
But what makes you think that it might be any better than what you already have and if you weren't able/ capable enough to make your current life worthy living how do you expect a different outcome for the great beyond.
Make your now your great beyond, then you won't have to worry about what exists after you don't.
