I don't place much stock in prophecy. Besides, the science is much scarier than some ambiguous prediction could ever be.
As the northern hemisphere seems primed to turn into a pure sea of oil, I was reminded of the Hopi Prophecy I read many, many years ago about the sea turning black. I thought at the time that it wasn't very likely that was going to happen, ever ... and I dismissed it as some crazy injun gibberish probably invented to spook tourists.
With the Deepwater Horizon rig disaster, it doesn't seem to just be some old ranting by some indians any more. Read the other signs listed in the sequence. Stuff like that would be kind of hard to see that far in advance. It appears someone did.
I know they are kept suitably vague and symbolic to keep you guessing ... but sometimes I wonder. Is it possible that there is a part of the human consciousness that is not bound to time? I don't know. I am undecided on the subject. Even if it is the case, it is obvious that this vision is very subjective and hardly an exact science. Was Edgar Cayce really seeing catastrophes in his visions as described in his sleep trances? Or was he seeing something? and then embellishing it with details that were unknown to him, in order to get revenues out of lonely middle aged women? Is there a collective consciousness capable of passing imperfect details about things that have not yet happened which sometimes leak into the standard, normal functioning of the human brain? I am not sure. I don't know for a fact. I have suspicions. I'm not convinced of anything in this regard. I most certainly did not start work on my own shelter because of Mayan prophecies or anything else based on some vague notion of clairvoyance. I started on my shelter ten years ago because I knew the facts.
Notice they say bomb shelters are a fallacy. That I recognize as being a very common form of delusion that is universal to low IQ people. I have to wonder if that is really part of the original Hopi prophecy or something tacked on by somebody else recently. The other parts appear to be much older, possibly authored back in the late 1900's.
