I found this video to be extremely fascinating, and I recommend watching it. It's only 9 minutes long. One of the best parts of this video is this rather mind-blowing implication: if you see your birth as point A on a line, and your death as point B on that line, then does that mean you are traveling that line in this life? NO. It means that you *are* the line.
That sure does away with the notion of free will, doesn't it?
