The ouroboros has several meanings interwoven into it. Foremost is the symbolism of the serpent biting, devouring, eating its own tail. This symbolises the cyclic Nature of the Universe: creation out of destruction, Life out of Death. The ouroboros eats its own tail to sustain its life, in an eternal cycle of renewal.  This secondary symbolism in an echo of the concept of infinity, of cycles without end, and an infinite universe without boundaries or limits.
