The prophecies of the Hopi, the Maya, the Bible, Nostrodamus, or Edgar Cayce can only come true if people sit back and watch things happen without exercising their FREE WILL.
So get ready for more change: next year will see an intense planetary formation that will force us to make the changes we need to make. These planetary energies are the same that occurred in the 60s, and now we have to implement that new vision into our cultural structures -- government, business, science, relationships.
This is only a brief answer to a complex question. I just finished reading Gregg Braden's book Fractal Time in which he discusses 2012 and what we might expect. He documents measurements that he says show us that the poles WILL NOT flip during this time. He also mentions that the person who found coded messages in the first 5 books of the Bible found a message that the Earth could be annihilated in 2012. OR NOT. It depends on US. We humans have great power within us, as all of our spiritual masters have shown us. Our hearts carry the answer. Not only does Love conquer all, but our hearts literally give off magnetism which can effect the Earth's electromagnetic field. So open your hearts and keep those poles working!
I believe that we are being initiated into a higher state of collective consciousness during these times. It is our task. It is our life's purpose. So will we be the heroes/heroines of our own lives and those of the world? Or will we fail the initiation and allow the patriarchal view - that death is THE END - to win out.
I'm voting for the end that becomes a new beginning.
