The salamander can automatically regenerate a limb. The hydra, a microscopic water animal, contains a lot of stem cells and can continuously regenerate itself – it is being studied for longevity properties.
There are intangible things that also endlessly regenerate. The bright optimism of the young.
Glowing promises of politicians and salespeople. Hope of oppressed humanity everywhere that somehow, things will get better tomorrow than they are today.
Oh, and hatred. Hatred is a ten-headed monster that endlessly regenerates, no matter how much love, tolerance or tit-for-tat we hurl at “it.” Repressive politicians promise justice and retribution. White Supremacists wave swastika flags, and sprout like dandelions all over the landscape. Mass migrations and refugee exodus happens over and over, with a predictable reaction, over and over.
Us versus them, my tiny infraction is nothing compared to your major crime, get your uniqueness off of my unique patch of earth. Hatred springs eternal. Fortunately, like cold to hot, so does love. The duality of nature seems to go on forever. It is beyond comprehension to know when it will all end.
