I don't think your insights were painfully obvious at all! "Foundational" is a much better way of putting it -- and that's in no way meant to seem a trifle of a thing. No matter how "advanced" you get, it's always important to practice your fundamentals!!! I think it's great to reassess things from time to time, and it's especially nice to be able to find out how others see things. Particularly with such a vague thing as gematria, which nobody seems to teach clearly (if someone even could!) it's easy for things to get convoluted, and even fall into the realm of OCD. So clarifying once in a while what the goals are, what the purpose is, is very helpful.
To build on this, I'll share my perspective on gematria, since often I'm baffled by the approaches of others, and hopefully if we share ideas I can get a better grasp of the perspectives of others... [If this should be another thread, let me know or feel free to copy/paste over to a new thread....]
So I've got an analogy in mind for my perspective on gematria, though it may or may not be perfect. Gematric data strike me as being like little shards of glass: pretty much worthless units in themselves, but capable of reflecting the light of insight. When one stumbles upon two shards that reflect the same thing, it can fire off an insight or break down a mental barrier.
The danger, as I perceive it, would be in getting too hung up on the shards of glass themselves -- the old Chinese saying comes to mind: "It's like a finger pointing to the moon; don't stare at the finger, or you'll miss the moon."
But this is my standpoint, and I'm interested in getting the perspectives of others! I'm not so self-assured as to think I've got it "right."
