Ouroboros
The Ouroboros is a self-sustaining, tail-eating snake,
This idea of the life cycle devouring its own tail can seem like a futile process where all that is achieved is ultimately destroyed. But this image of Ouroboros suggests a way to perceive it as an enfolding where the past (the tail) appears to disappear but really moves into an inner domain or reality, vanishing from view but perhaps still existing in some kind of virtual sense.
