Pain is like energy. Energy can never be destroyed, just transfered. When electricity is put into a light blub the energy is transfered to light and heat. But it's never destroyed. Pain is like that. Say, a man has a bad childhood, he can't express his anger properly so he takes it out on his girlfriend by hitting her, she gets so depressed by this that she ends up killing herself, leaving a little sister behind who grows up depressed cos of this, she has a kid too young, who has a bad childhood... That's far too simplified. But it never ends, pain just goes on and on, no matter how we try to stop it. Ending my own pain causes pain to others, even just talking about it. The only way to end it, to end the cycle, is to internalise it. Bury it deep and make it end with me.
