I know what video your talking about. My dad wanted me to watch it, so out of curiosity I did. Of course I had been drinking a lot of wine leading up to this incident, I would not have been interested otherwise. Anyway, your right. It said nothing about the false prophecies of dates set of the end of the world time and time again. I was insulted really. This is their explanation? Bah humbug. Anyway, my dad finished by telling me not to trust the internet. I haven't seen him in a while because I just can't handle the high level of B.S. that fills his house and drowns out any logical thought. The video didn't answer any questions I had about the false prophecies, and neither did my dad. Stupid video, but hey, I was drunk and didn't even watch all of it because I made the excuse I needed to go make a phone call and smoke a cigarette.

Rise up nimbly and go on your strange journey 
to the ocean of meanings.

The stream knows it can't stay on the mountain. 
Leave and don't look away from the sun as you go, 
       in whose light you're sometimes crescent, sometimes full.
