Chuang-tzu once told a story about two persons who both lost a sheep. One person got very depressed and lost himself in drinking, sex, and gambling to try to forget this misfortune. The other person decided that this would be an excellent chance for him to study the classics and quietly observe the subtleties of nature. Both men experience the same misfortune, but one man lost himself because he was too attached to the experience of loss, while the other found himself because he was able to let go of gain and loss.
