Yes its the Ouroboros, you see it everywhere. Satan swallowing his tail symbolizing the secret nature of the universe. Creation out of destruction, life out of death, order out of chaos. It will be game over at the end of the thousand years for satan though.
I have been Google-ing for info on the Ouroboros but nowhere online can I find anyone else sharing this particular theory regarding this image; that satan really thinks he can obtain eternal life.
I was shocked by the video, because I had always assumed that satan already knew he was beaten. But if he really is so deluded to think that he can actually succeed, that makes him a far more dangerous enemy. Not that he can defeat us in Christ. Anyway...
