Here's a story from Thich Nhat Hanh's book, Being Peace, to illustrate the principle of what he calls "dependent co-arising."
* * *
Suppose you and I are friends. (In fact, I hope we are friends.) My well-being, my happiness depends very much on you, and your well-being, your happiness, depends upon me. I am responsible for you, and you are responsible for me. Anything I do wrong, you will suffer, and anything you do wrong, I have to suffer. Therefore, in order to take care of you, I have to take care of myself.
There is a story in the Pali Canon about a father and a daughter who performed in the circus. The father would place a very long bamboo stick on his forehead, and his daughter would climb to the top of the stick.... One day the father told the daughter, "My dear daugher, we have to take care of each other. You have to take care of your father, and I have to take care of you, so that we will be safe. Our performance is very dangerous." Because if she fell, both would not be able to earn their living. If she fell, then broke her leg, they wouldn't have anything to eat. "My daughter, we have to take care of each other so we can continue to earn our living."
The daughter was wise. She said, "Father, you should say it this way: 'Each one of us has to take care of himself or herself, so that we can continue to earn our living.' Because during the performance, you take care of yourself, you take care of yourself only. You stay very stable, very altert. That will help me. And if when I climb I take care of myself, I climb very carefully, I do not let anything wrong happen to me. That is the way you should say it, Father. You take good care of yourself, and I take good care of myself. In that way we can continue to earn our living." The Buddha agreed that the daughter was right.
