>>but I also have to come to grips with the reality of my religious experiences. Are they simply neurons or some psychological trick my brain is playing with me, or has a higher being worked within my life and the lives of multitudes?
This is where Bayes theorem would come in handy. Do we know of any psychological tricks that brains do? Well, for one there is the supposition that the brain is playing tricks with you, rather than the reality that the brain IS you, among a great number of other clear biases. And how many supernatural superbeings do we know of that alter mental states? Well, none. So we'll have to assume one ad hoc, without any motivation or plausible physics by which it could exist. So which theory is more likely? Something we know can and does exist, exists or that with no evidence in support of it, a being with superpowers in an invisible realm is fiddling with your brain to tell you to do things you want to do?
Keep in mind this superbeing is also telling other humans radically different and contradictory things also directly in line with their personal wants too.
The explanations that former religious people give that they realized that they were telling themselves these things the whole time explains everything. The explanation you are leaning towards supposes superbeings in invisible realms telepathically communicating with everybody and telling different people contradictory things, but perfectly in line with their wants.
