What does it take to reach 'critical mass'?

In Gregg Braden's book "The Divine Matrix", Gregg states
“The minimum number of people required to jump start a change
in consciousness is the square root of 1% of a population.”

The population of the planet is about 6,795,000,000

This means.... only 8,244 people are needed to bring about a shift in awareness… to bring about Peace, Harmony, Unity and Balance on the planet once again.  ONLY 8,244 Positive People!
