I think I can answer one of those questions, being a long time follower of this thread. You have to understand what the Akashic Records ARE. The Akashic Records are, in fact, everything. The Supreme Being is a subset of the Akashic Records. Everything the Supreme Being does is written down, and without it being written down, it didn't happen.
The thing about Akashic records is that no one IS an Akashic. It's not a personal kind of force. But you can do things TO the Akashic records... if you can get past the "librarians". Of course, a Supreme Being should have no trouble at all dealing with librarians, since by definition, the Supreme Being is more powerful than said librarians. So the Supreme Being can go ahead and start tinkering with the library holding the Records... but remember, the records here are what holds the power we're talking about, and if the Supreme Being wasn't careful, maybe some lesser power could slip into the library, sneak past the librarians somehow, and change that Supreme Being him/herself...
That's how it works, to my understanding.

I have always imagined that Paradise will be a kind of library
For a picture of what the Akashic Records are like.
