The Sacred Three
Three numbers bound by digital root 9
If you knew the magnificence of 3, 6, and 9, you would have a key to the universe.
-- Nikola Tesla
The numbers 108, 369, and 693 all share a digital root of 9. Break any of them down: 1+0+8 = 9. 3+6+9 = 18 = 1+8 = 9. 6+9+3 = 18 = 1+8 = 9. Nine is the number that always returns to itself -- multiply it by anything, the digital root stays 9. Tesla saw this as the fingerprint of the universe's operating system.
