They did not take pride in success.
They never plotted their affairs. From this basis, they could be without regret if things went wrong, remain free from self-congratulation when they went right.
They received whatever came and enjoyed it; they lost whatever went and just let it go.
Their food was plain and their breath deep. In fact, the perfected breathes all the way to the heels while the multitude breath just to the throat.
The perfected of old slept without dreaming and woke without concerns.
The perfected of old had no clue about loving life and hating death. They came to life without celebration; they left again without messiness. Calmly they came, calmly they went—and that is all. They never forgot where they came from; they never inquired about where they would end.
They could climb high places without getting scared, dive into water without getting soaked, and pass through fire without getting hot. Their understanding was such that they could rise up and join Tao at all times.
