The only thing that can work for everything is your own personality or what you have inside yourself. That is the only part that will always be relevant to you.

>it seems like a very confusing web of information where everyone preaches their subjective view of this, which is kind of insane. I tried to tie it up together, but was left with madness so I just came to the conlusion that there isn't a perfect divine answer that is composed of everything. I think I can clearly see a few instances where certain practices spread from country to country and changed a bit, but this doesn't help. It's sad because there isn't anything you can do that will just work, like a computer that simply starts up when you press a button.
You're looking for a way to automate life. If you do this and put yourself under the influence of such a system, you become an automaton yourself. There is a way to do this, but do you want this? If done wrong you become the slave of contraptions you cannot change, and they may lock you up and restrain you seemingly indefinitely.
Reality is only shared in the sense of genes and memes. Small formulas which can be used by a certain group of beings. Not everyone will look the same. Maybe someone see it as a goal to find such a thing, to create some kind of unity, but why?
I think the answer is only inside yourself and not in finding such common ground, aside from the part which is true to yourself. Don't seek communion with others for itself. Let the shared ground appear before you where you are, with no effort.
