So you say, and you may be right for all I know, but the point is, you don't really know that yoga of the type outlined, say, by Patanjali has been around for 5000+ years. All you can say with any confidence is that the tradition predates by an unkown length of time the first texts.
That is true, but the yogic saying is not a type of yoga. Of course I can't say that it is 5000+ in that sense, because we lack evidence. The saying is subcurrent "Yoga" if you take my meaning. |

Haw! That checkered shadow illusion is a hoot! I wonder if it matters that the cylinder is green.
The one counting the black dots has no dots, right? The first one is moving in the peripheral. Now, I'm going to guess that since the brain is actively processing signals in real time that certain stimuli like complementary colors interfere or modify in some way the processing of information. Note that when we watch real movement it does not "hurt" to see it. But staring at the first illusion "hurts". So it seems to me there is some scrambling of the signals going on that our brains object to. |

Unfortunetly, it didn't move for me. However, as to the reason for why it moves, I would venture a guess that it has to do with how fast your eyes can trasmit the information to your brain, and your brain can provide you with a mental image of a complex set of images that it is in the process of recreating, as you shift your eyes.
More specifically, I would think that there is a reeidual overlap of the complex image in your brain that is not entirely "cleared" from your brain, as it receives the next image of what your eyes are seeing is you shift them slightly from one position to another. A sort of double or superimposed image results and gives the appearance of motion, as your brain is "clearing" out a previous image, while at the same time, it is prodicing and has produced the next image that your are seeing, in a slightly different position. It's just a guess, but it would seem to be logical if you work with computers, as I do. |
