The Ourobras is a snake swallowing its own tail while growing a new body. This is the spiritual embodiment of a cosmic cyclical view: the reciprocation of construction and destruction, the alternation of life and death. From an ecological point of view, Ourobras needs to eat its own tail to survive, and its own tail brings it infinite food, which is another cyclical pattern of eternal rejuvenation. It represents cyclical self-development. It is in the state of a self-feeding cosmic primordial creature, which is immortal and has a perfect biological structure. From a biological point of view, it is the most ideal state that a creature can achieve, deriving light from light.
