It seems plausible to me that when gaia fully ascend into fifth dimension there would be natural catastrophes occurring across the planet to symbolize the completion of her ascension or her rebirth. This could be the result of a sudden tremendous upliftment of energy on the planet in the moments of gaia's full glorious rebirth on the higher plane. Maybe some more evolved souls could ride this great release of energy to fully activate their kundalini and ascend along with the mother. It's interesting some people have been talking about the earth pole shift. They say that the inner core of the earth has been shifting, upon its completion in 2012, the outer crust of the earth will turn 180 degrees (symbolic of the gaia's rebirth), and because of this there will be a couple days of darkness. It would be like the darkest night just before the dawn (before gaia's enlightenment), one may be able to take great advantage of this powerful transformative energy during this time if one can fully embrace this darkness together with the mother. It's also been said the last ice age was a direct result of the pole shift, which resulted in the early civilizations being wiped out. There's no reason to think the same magnitude of earth change will not happen this time.
I find this perspective looking the earth ascension really interesting though it does sound a bit far fetched, I'd love to hear your thoughts on this.
