The reason everyone has their panties in a bunch about 2012 is because we're all waking up to our power. It's becoming common knowledge that our thoughts create. If you don't want to take responsibility for the reality you live in, you will experience chaos during this time. But if you do decide to take responsibility for what you think about, you're in luck. Heaven on Earth is now yours.
What you think about, you bring about. If you think mass destruction of the planet is what it will take for everyone to start being better people, then that's what it will take. Just remember that is a reflection of your internal world. If you believe humanity needs a serious beating before we change our ways, that only means you're not ready to change yet.
You can start living in the prophesied post-apocalyptic utopia now. All of the doom and gloom about the Mayan calendar and comets is just a metaphor for what needs to happen inside of you. If you don't believe thoughts create, your entire belief system is going to be destroyed. And if you are still identifying as your belief system, then you will feel like you are going to die. But that is only your egoic mind talking. You are not your thoughts. You don't have to be a victim of your thoughts.
If you want to survive the awakening, just start thinking about what you want. Start feeling good. Start having fun and playing. Release your fear. Stop worrying. Your mind may be afraid of annihilation, but there is a whole lot more to you than your mind. You are infinite intelligence, you are god! Start acting that way.
If you feel now is the time to take a look at your current belief system, check out the School of Life Design lessons. If you already know thoughts create but want help getting better at directing your thoughts, start writing about what you're grateful for and what you want as many times a day as you can. The more you practice, the better you'll feel and the more control you'll have over your life experience. I post all of my thought direction writing in my lifestream if you want an example.
