This is another fascinating information, so, I like to know if other have more thoughts about this subject.

June 13, 1998

A: Who are your prime numbers?

Q: The dwellings or the mystics, or do you want specific numbers?

A: Yes.

Q: How do we find out who are the prime numbers? Do we plot...

A: Who are the first 3?

Q: (A) 1 2 3 are the first three prime numbers...

..all of creation, of existence, is contained in 1, 2, 3!!! Look for this when you are trying to find the keys to the hidden secrets of all existence... They dwell within. 11, 22, 33, 1/2, 1/3, 1, 2, 3, 121, 11, 111, 222, 333, and so on! Get it?!?!

Q: When you say that the secrets of all existence dwell within 1 2 3 or variations thereof, what kind of secrets are we talking about here?

A: All.

Q: Well, name two at the top of the list just so I know where we are going here?

A: You can do that!

Q: Are we talking about secrets of physics?

A: Yes.

Q: Are we talking about secrets as in encoded words?

A: Yes.

Q: Are we talking about the Fibonacci series?

A: Yes.

Q: (A) Continuous fractions?

A: Yes.

Q: (A) That means all...

A: Yes.

Q: So, how can we most effectively utilize this information in some way that makes it useful?

A: You have.

Q: How have I utilized it?

A: By receiving it.

Q: Now, the other night, in front of the psychomantium, I did not exactly have a vision, but something came into my head, and the idea was that prime numbers are important because, the principle that they are only divisible by themselves and by one is indicative of the fact that they are direct links, channels, or conduits to seventh density, or first density, or something...

Q: Okay, that is sort of what I mean, that they are, in a sense, gateways - would that be a good term?

A: Close.

Q: How does one utilize the energies inherent in prime numbers in this respect? Do they represent frequencies or frequency relationships?

A: Verities.

Q: Is there any formula, or any thing about prime numbers that makes it easier to find them... anything about them that is unique?

A: Pyramidal.

Q: Pyramid relationships would help one find prime numbers?

A: Graph.

Q: A pyramid type graph. Okay, anything else about prime numbers? When you said that they were the 'dwellings of the mystics' I had an idea that a prime number could be a dwelling of a mystic because the individual would express in some manner a frequency that related in some way to a prime number. Is that somewhere along the line...? That mystics can traverse all densities because of frequency?

A: Something like that.

Q: My next thought was that it could indicate actual places or locations in space time on the planet that would be represented by coordinates.

A: Zuber.

Q: What does THAT mean?

A: Research.

A google search produced Jean-Bernard Zuber who could fit the profile in this context as he is an emeritus professor in mathematics of some sort or other:

My recent research interests lie at the interface between Quantum Field Theory and mathematical physics.

Subjects on which I have been working recently include
• Conformal field theories, integrable systems and graphs Graphs
• Matrix integrals, combinatorics and knot theory Knots
• Lattice loop models and combinatorics FPL and tilings
• Lattice models and logarithmic conformal field theories

I think that is the correct Zuber. From the 9/14/2002 session:
Q: (L) Well a grand cycle is what, 309,000 years? So how does that relate? (Ark) Essentially it defines a unit of time. So if I say frequency is equal to 1, it means one grand cycle, if I say frequency equals 10, it means 10 oscillations per grand cycle, and so on, okay. Okay, it's a kind of an answer. If anything, it makes sense. I can do something with it. At some point when we were talking about these prime numbers, you mentioned a name and the name was Zuber. I asked what does it mean and you answered 'research.' Well I was researching, of course. I was just looking about, using google. I was looking for Zuber and prime numbers and something like this. And, surprise, surprise! There were essentially, very few references, and all of them were to Matti Pitkanen. So he has a lot of papers about prime numbers and theory of everything based on prime numbers...(L) How did Zuber get in there? (Ark) Zuber is one of these references because one of the references is a famous book by, which I even have, by physicist named Zuber about quantum field theory. So my question is, is the Zuber of the book on quantum field theory and conformal theories and so on, the right Zuber?

A: What do you think?

Q: (Ark) I think chances are 50%, and chances are that he's not the same.

A: 80 percent!

Q: (Ark) 80%, that doesn't help much! I have this paper by Mattie Pitcalean here, maybe you will reevaluate this. The paper is called Quantum Criticality and 1 over F nosxe. and here's Zuber. Let me read it, hmm...conformal invariance, yeah, it must be the same. Okay, 90 percent. (laughter).

A: 100!

Side Track while reviewing Silbury Hill ... Not expecting to find anything like this, I came across opposing prime numbers. I found that there are a few angles that are prime numbers and have opposing angles that are also prime numbers. Here is a list of them. “Angles in opposition that are prime numbers; 7/83, 11/79, 17/73, 19/71, 23/67, 29/61, 31/59, 37/53 & 43/47”. What does it mean? I have no clue, at least not yet, but it is a clue, Haiku ...

7/83 7+8+3=18 1+8=9
11/79 1+1+7+9=18 1+8=9
all of the fractions above = 18 therefore =9
May not mean anything! But it is a pattern...

Today's session is all about numbers and specifically 737.
I noticed this number twice in the same day, really it was moments apart. First the plane issue. Second was the number of inmates on death row in California. Coincidence, I am not too sure. Let’s look at the number.
737 is not a prime number, it has integers that divide 737 as follows: 1, 11, 67, 737.
The individual numbers 7 and 3 are prime numbers. Two of the integers are prime numbers. That is 11 and 67. That makes 737 a composite number of prime numbers 11 and 67.
Seeing it twice like this, not to mention the number of plane mentions in the news, may be a clue. Having so many prime numbers in 737 and integers/composite numbers 11 and 67 may also be a clue.
The C’s stated that prime numbers are important. And there are too many prime numbers here not to take notice. Did anyone else see 737, 67, 11, 7 or 3 numbers anywhere else? It might be important.
Looking at what we have right now in implications, I would say that 737 is a number that has doom written all over it. Crashing planes, death row inmates only spell disaster or death.

The first lucky prime. Since lucky numbers are lucky enough to repeatedly appear in this book, let's take a moment to define them. Start with the list of natural numbers: 1, 2, 3, ... , and cross out every second number. The second number not crossed out is 3, so we cross out every third number, leaving 1, 3, 7, 9, 13, 15, .... The third number left is 7, so we cross out every seventh number---repeat forever. What remains is the sequence of lucky numbers: 1, 3, 7, 9, 13, 15, 21, 25, 31, 33, 37, 43, 49, 51, 63, 67, 69, ....

So, I think I understand something like,

‘The key to the hidden secrets of All Existence dwell within prime numbers 1 2 3 or variations of first three prime numbers
And they are important because they are direct links/channels/conduits to All Densities!’

And then I keep thinking about what is represent non-prime numbers that Total Non-Existence.
Then I found answer to that in another Session Transcript!

December 10, 1994

Q: .......(L) In terms of major STS, this may or may not be related, could you tell us the nature of a Black Hole?

A: Grand Scale STS.

Q: (L) Is it like a being that has achieved such a level of STS that it has literally imploded in on itself in some way?

A: Close analogy.

Q: (T) Possibly an entire civilization of STS?

A: No.

Q: (L) Well, maybe a civilization can't do it because that implies working together. It must need to be an individual being.

A: Black Holes are a natural force reflection of Free Will consciousness pattern of STS. Notice that Black Holes are located at center of spiral energy forces, all else radiates outward.

A: No.

Q: (L) Is it a radiating wave?

A: All in creation is just that: a radiating wave.

Q: (L) Now, you say "spiral" energy forces, and you also have said that this wave is a spiral. Is the central point of this wave that is spiraling, a black hole?

A: No.

Q: (L) Where does the energy go that gets sucked into a black hole?

A: Inward to total nonexistence.

Q: (L) Well, that is pleasant. And what happens to energy that is "total non-existence"?

A: Total non-existence balances total existence. Guess what is total existence?

Q: (L) Well, is it kind of like a balancing force?

A: "God."

Q: (T) Are we talking about the creator god as in the Pleiadians?

Q: (T) What is the difference between the Prime Creator and "God?"

A: None. As long as you exist, you are of the Prime Creator.

Q: (L) Now, this stuff that goes into Black Holes, that goes into non-existence, is that, then, not part of the Prime
Creator?

A: Correct.

Q: (L) How can Prime Creator lose any part of him or itself?

A: Prime Creator does not "lose" anything.

Q: (L) Well, then, how would you describe this energy that was in existence and then is no longer in existence because it has become or gone into a Black Hole?

A: Reflection is regenerated at level 1.
Q: (L) So, this energy goes into a Black Hole and... does it come out on the other side?

A: No.

Q: (L) Does it become like a primal atom?

A: No.

Q: (T) Does it go back into the cycle?

A: No. Reflection regenerates as primal atoms.

6 4 1 case 4 "have option for 8 in sts stack case" 6 have none existance sts for balance n 1 hide 9 from reflection. this look like basic hologram concept in "back" to 1 2 3 thro field of 7

This is another fascinating information, so, I like to know if other have more thoughts about this subject.

I am not sure about the secrets of all creation, but many of the concepts relating to your post can be found in the primes. This is my own personal subjective interpretations of some of the relating clues. It does not mean any of it meets the level of the intended meanings. None the less, a lot of it seems to fit in one way or another on a very simple basic level.

I think in the primes you can find parallel ideas for some of the concepts, such as:

Primes --> pyramidal --> pyr --> fire --> light --> frequency of light.

A connection between the square root of 13 (p-adic) and phi.
How do gravity, electricity, sound, light, all EM ( waves ) intersect or what do they have in common.

A primes object that demonstrates:

A double structure
Has a structure where the micro and macro are kind of swappable, totally interchangeable, invertible
Has an idea of perfect balance
Allows one to visualize inwardly and outwardly simultaneously
Contains the idea of something like flipping backwards and inside out
Has a concept for gravity and consciousness
Has a concept of expanded gravity, a great expansion of the same concept as we have
Gravity as a binder
Gravity as consciousness expressed
Consciousness as inverting the gravity geometric model
Consciousness is contained within the expanded realization of the gravity model
The synchronous relationship between gravity and consciousness
Union with the one

The attached image is the primes mathematical object that I think contains all of these concepts.
The attached PDF is kind of the journey I took to find these relationships I subjectively see.

I am an amateur with very basic math skills so I hope the language is not too scattered or mucked up.

For the attached PDF there are some simple things you need to have a basic grasp of:

You need to understand a very minimum about algebra, multiplication and distribution.
You need to be able to recognize patterns.
You need to understand what roots and powers are and what a power series is.
You need to understand summation of a simple power series of an inverse natural number converges to the next larger inverse natural number. This one is pretty simple and I try to explain it if you don't understand the concept.

Numbers are definitely not one of my strenghts (need to work on it indeed...) so maybe this is a silly question...
There seems to be another current out there very much into the 3,6,9 pattern as holding the secrets of the universe...
Is this the equivalent of numerical battle of STS and STO?

Today's session is all about numbers and specifically 737.
I noticed this number twice in the same day, really it was moments apart. First the plane issue. Second was the number of inmates on death row in California. Coincidence, I am not too sure. Let’s look at the number.
737 is not a prime number, it has integers that divide 737 as follows: 1, 11, 67, 737.
The individual numbers 7 and 3 are prime numbers. Two of the integers are prime numbers. That is 11 and 67. That makes 737 a composite number of prime numbers 11 and 67.
Seeing it twice like this, not to mention the number of plane mentions in the news, may be a clue. Having so many prime numbers in 737 and integers/composite numbers 11 and 67 may also be a clue.
The C’s stated that prime numbers are important. And there are too many prime numbers here not to take notice. Did anyone else see 737, 67, 11, 7 or 3 numbers anywhere else? It might be important.
Looking at what we have right now in implications, I would say that 737 is a number that has doom written all over it. Crashing planes, death row inmates only spell disaster or death.
