Ok so, I was rude, and I apologise for that.
However, I still believe you are wrong to say that Yog isn't above infinite D, so I'm going to bring up a few points.
First, I'll address your argument that Yog is only 6D.
From what I understand of your argument that Yog is only 6D, it's based on two quotes. The first is:
"All descended lines of beings of the finite dimensions, continued the waves, and all stages of growth in each one of these beings, are merely manifestations of one archetypal and eternal being in the space outside dimensions."
This is where you get the idea that the mythos has finite dimensions and then somone outside those dimensions. Because it mentions beings of finite dimensions, and then the eternal being in the space outside dimensions.
And the other quote is:
"They told him that every figure of space is but the result of the intersection by a plane of some corresponding figure of one more dimension—as a square is cut from a cube or a circle from a sphere. The cube and sphere, of three dimensions, are thus cut from corresponding forms of four dimensions that men know only through guesses and dreams; and these in turn are cut from forms of five dimensions, and so on up to the dizzy and reachless heights of archetypal infinity."
And this is where you get the idea that the mythos only has 5 dimensions, correct? Because it only directly mentions up to forms of five dimensions. So anything outside those 5 dimensions is only at the sixth.
Now, importantly. Am I correct in saying that you think that "the dizzy and reachless heights of archetypal infinity" is the "space outside dimensions" where that "archetypal and eternal being" lives? That you believe the number of dimensions go up to 5 and then there's this place called "archetypal infinity" that exists outside those 5 dimensions?
