Tuning With Nature: Harmony Tunes In Nines

A good summary of why 3,6 and 9 are critical numbers. The number 9 contains all other numbers, and the calculations of many sacred forms and phenomena reduce to the number 9 (or 3-a factor of 9, or 6-a factor of 3). Multiples of 9 always reduce to itself. In this sense, 9 might be considered the "God Number"- a self containing number that serves as the building foundation for all other natural vibrations and forms.
