"When she first died, how could I have escaped feeling the loss? Then I looked back to the beginning before she had life. Not only before she had life, but before she had form. Not only before she had form, but before she had vital energy. In this confused amorphous realm, something changed and vital energy appeared; when the vital energy was changed, form appeared; with changes in form, life began. Now there is another change bringing death. This is like the progression of the four seasons of spring and autumn, winter and summer. Here she was lying down to sleep in a huge room and I followed her, sobbing and wailing. When I realized my actions showed I hadn't understood destiny, I stopped."
— Zhuangzi, Daoist philosopher, 369-286 BC
