In "astrology / numerology" topic there is a discussion on 'seven planetary genii' seemingly present in all religions on Earth.
In a sociology textbook, I've read that seven persons is the maximum number for a close conversation to occur without problems.This explains why the Thaori are seven, and why the highest leaders of a country should be neither more, nor less than seven in number.

This is really interesting connection. However, we need to explore assumptions and logic behind these sociology conclusions to determine if they indeed do provide a sensible explanation.
