(Dear Sealchan,
that's an interesting "movie". I never thought about the ouroboros that way... when I look at the uroboros now, I associate to the "relationship" between the mind and the body, between "spirit" and "matter". Perhaps because I have just read an article mentioning a theory about the difference between postmodernity as questioning the hegemony of the modern image of humankind as the ruler of the world, etc, vs. returning to pre-modernity and giving back all the control over our lives to God / destiny / karma, etc.
So at the moment what I see in the uroboros symbol is that when the mind / spirit explores itself, it will finally have to realize that it is "feeding" on the body / matter, and that spirit is an aspect of matter, or, "made of" matter, just like the brain is body, while matter, too, is an aspect of spirit, that it lacks, and has always lacked the emptiness the spirit wished so much to "fill", as matter is always and already full of itself, and spirit is already part of it, and vice versa, et cetera ad (in)finitum.
love,
Maria)
