Nine holds within it a powerful resonance within our holofractographic, base-10 reality. Nine is the largest number in the decimal system. Nine is really the largest number of all, as every other number thereafter is a reflection of the Ennead, expressing itself in scalar expansions and contractions of 10.

10 is not a number, but more of a concept, or you could say it’s Nature’s way of organizing herself. The Pythagoreans considered there to be only 7 numbers in reality. Unity and duality, 1 and 2, were not considered numbers. Numbers began at three and ended at the most auspicious of all, NINE.
