Sure, they can explain their surface beliefs well enough for understanding. I’ve been at that game for fifteen years.
What’s difficult to convey is why I feel that way. I’ll take a stab at answering why and hope it’s not too abstract.
Mystic understanding relies on the axiom that any experience is going to convey some form of truth. If you’re not familiar with the term axiom, it means something you take as true and build off of without trying too hard to justify it.
So my mystical experiences are going to convey some kind of truth to me. How do I work out what that truth is? Well, you need to integrate and think carefully about those experiences. If I meet Lucifer in trance, I have to figure out what that means. That involves not just trying to understand what it was that I just met, but also why it was that I met Lucifer specifically.
While I’m busy integrating one spiritual experience, my mind doesn’t really wait for me to catch up. When it’s ready, I have another spiritual experience.
Spiritual experience is by design dense and hard to understand. But there’s an underlying logic to it that you learn how to move through the longer and more you do it. I had my first mystical experience when I was like 19 and part of a Wiccan coven. 15 years later and I’m still nowhere close to mastering it. There’s always something new to dive into.
The spiritual landscape has a multitude of dimensions that you need to think about carefully in order to understand them. And it blends into your normal life in order to help clarify things.
Once you’ve been doing it long enough, the idea that you can go back, to deal in a purely rational frame, well it just feels like slumming it. The spiritual world is just so much fun.
