As far as this thing about the Keystone goes, the non-esoteric meaning is that the Keystone is the people.
The esoteric meaning is that the Keystone is all of us. This also means that Keystone is the people, so these definitions aren't actually disagreeing with each other.
There's a story, I don't remember where it's from, maybe the Bible I don't know, but it shows up in the lot of Christian mysticism, about how some builders were constructing some building and they were sent shaped stones from a quarry. The stones were always shaped to fit in just a certain way. Well, one day a very weird-shaped stone unlike all the others showed up and nobody knew what to do with it.
But after a series of confusions and misunderstandings it was revealed that this odd stone was going to be the centerpiece for the arch and it would be that which all of the other stones were sort of depends upon in order for this arch to work.
And the moral of the story is considered a secret esoteric thing but I don't care anymore so the moral of the story is that all of us are created perfectly imperfect, and those who choose to follow the father are the son and so on. We're all divine creations and we can choose which father to serve.
There's another esoteric meaning of the Keystone which involves the eye and the centerpiece of the eye, lots of things to say there, I could talk about it for quite some time actually, but whatever, it's your eye, it's you, all of this involves you, you are as much God's creation as anything else.
So all this arguing about the Keystone being esoteric or not is really kind of silly.
Doesn't really work on me, so hello again.
