Perhaps in "your" world "five" is spelled "five". Lately for me it is "phi-ve". For the number 5 plays a huge part with the Phi ratio. The pentagram is a great example of this. However I do appreciate your feedback and I do agree with the "mod 9" concept you had mentioned. Marko Rodin himself refers to it as "mod 9". I for one agree again. 0 and 9 are the same essentially I am coming to find in regards to Vortex Based Mathematics. 0 is the singularity, and 9 is the whole, completed, finished process before starting over again in a new cycle, i.e. hence 10 is merely 1 for 1 + 0 = 1, 11 is merely 2 for 1 + 1 = 2, 12 is 3 and so on. Also hopefully I understand your question correctly when you say "how you decide what edges to draw in your nonagons". My answer, I hope indeed correct would be simple. The numbers themselves showed me where to connect the dots on a nonagon to find its geometric constituent themselves. I honestly had no idea what the outcome would be going into this. I have another post where I demonstrate this exact method via placing the doubling PA-ttern of 1-2-4-8-7-5 within a tetraktys and simply added, reduced the sum to their "digital roots" and placed my findings within a box of rows and columns and completed the process until the PA-ttern came around full circle to the beginning again like the ouroboros. Once complete I then placed these numerical PA-tterns with in a nonagon to again find its geometric constituents by simply connecting the dots, the appropriate numbers to be exact. I also have a post where I have done this as well with the "double X" / "dos equis" / Masonic "Square and Compass" symbol or triple merkaba with simply by playing around with our base numbers. PA-tterns within PA-tterns I tell ya of oscillating "solfeggio" number groups that are so orderly and perfect and come around again perfectly full circle like the ouroboros in 9 times that to me it is impossible that this can just be the work of coincidence / chance or what some refer to as merely "Apophenia", the tendency to attribute meaning to perceived connections or patterns between seemingly unrelated things. In which as far as the methods used in this post or my other post I mentioned above is merely not the case I am finding. There is a perfect order / language here. I appreciate your insight brother. I am still learning myself so your input does indeed help me quite a bit to better understand "mod 9" or VBM. So I must say I truly thank you and appreciate that. Namaste brother. :)
