First, let me say thank you for such a nice and reasonable response.
Please do not take what I am going to say as metaphysical, it's well beyond that, which must first be understood. It is one thing to sit in a place and contemplate something or somewhere else, but something complete different to actually go. In this case, one must actually believe...which I understand is difficult without some good reason. In my case, I tried everything else first being unwilling to try it first, and when I had exhausted all other possibilities, it was simply a process of elimination. Bottom line, when I came forward...I didn't believe ANYTHING...but I was sincere. So...rather than believing in something you have no good reason to believe, you at least have to be sincere. This may not seem like life and death to you, but at the time, I had already passed that point, thus my sincerity was indeed acceptable. Your own sincerity is the gauge of whether or not you will be able to see behind the curtain. This test, this demonstration, is not on the faith talkers, it's on you.
Consider relativity. Consider one reality where one believes beyond a certain point, and consider another reality where one only believes up to that certain point. I am no expert, but it stands to reason that the only person who will get beyond that certain point, is the one whose reality includes it. Sorry, I'm not sure that helped.
Bottom line, you are going to have to put a toe out there and be willing to get it wet. Scary, but that's how it's done. If we were talking about dancing or talking to some big scary figure, you might even need a push. In the case of dancing, you have to pull your fingers out of your ears and hear the music, feel the beat, let your backbone slide. Again, this is on you, and you don't have to do it. But before you just write all this off as crazy talk, think about how YOU would describe something like, say, love: It exists, it's invisible, but it's real, and you sound like an idiot no matter what you say. But one thing is true...without it, you don't know what you're missing.
Keep seeking. Step up. Be sincere.
