Overall, I find that unconvincing.

Culturally, there's not a lot of repetition of numbers (unlike in Christianity and medieval Europe) beyond the triads of deities that presided over the major cities. There's no standard number of judges/spirits/etc, etc that would lead us to believe certain numbers had a mystical power.

I could be wrong, of course, but I found the evidence to be too weak and reliant on other nations and cultures and eras.
