What's the mathematically optimal way to get into a positive afterlife? Some religions advertise infinite afterlives, in which case getting into the best possible one should be the top #1 priority of everyone. So mathematically speaking, do I worship a single god, several of them, none of them, and do I contribute towards building a godlike AI? Or is the optimal solution to just ignore all of this (because that's what God/Super AI wants). Help. I ask /sci/ because you've got non-brainlet users.

Pic related, because going to Gensokyo after death is one possibility.
