Ascension on a global scale is what kalki is talking about. Though it isn't a religious based concept, it does have a trace of Hinduism theology to it. The critical mass of the ascension mission of Kalki must be achieved by 2012.

Who is Kalki ?

He is the founder of a movement known as the Oneness University who's mission statement states in part that they will bring every human into the Golden Age. They themselves do not need to reach the entire human population directly. Their job is to work at enlightening 64000 souls. Having reached this number they believe that the natural phenomenon of critical mass will take over and that the rest of humanity will funnel into the tunnel at a quantum velocity and the entire human psyche will be elevated into this frequency. From this new paradigm or singularity, every human will be in the frequency of one.
The inititial 64000 will be reached through a transfer of divine energy known as Deeksha(diksha). This deeksha energy is transferred through the hands of a qualified diksha giver, a channel opens up between the two and cosmic energy binds the two as one.
This is similar to a process of downloading an existing program from one computer to another.
Is this for real?
Kiara Windrider has pondered deeply on that question and has termed the merits of the Golden Age Foundation and the Oneness university as Enlightenment 2012. Windrider explains his observation and comments on his understanding of these claims in a book called Enlightenment 2012 : Kalki and the Golden Age.
