First Reading of Chapter One of the Upper Xici: Heaven and Earth Take Their Places, and Virtue Is Formed Through Ease and Simplicity
A close reading of Chapter One of the Upper Xici within the context of pre-Qin thought, moving through the layers of Heaven and Earth, Qian and Kun, the firm and the yielding, image and form, change, ease and simplicity, virtue and achievement, and the taking of one's place -- to see how the Yi runs through the Way of Heaven, the Way of Earth, and the Way of Man.

XXXIV. Why the Virtue of the Worthy Is Measured by "Endurance"
Time is the surest test of whether virtue is genuine or false. Momentary generosity may arise from excitement; momentary reverence may arise from fear; momentary integrity may arise simply from having nothing worth taking. Only when a person holds fast through poverty and low station, through wealth and honor, in solitude where no one sees, and under the gaze of the multitude, can one see that virtue has truly been formed. Hence endurance is not an honor added onto virtue, but virtue's own inner mark.
The Master said, "Only when the year turns cold do we know that the pine and cypress are the last to wither." In ordinary times, grasses and trees all flourish alike and are hard to distinguish; when severe cold arrives, the nature of the pine and cypress is revealed. A disordered age, hardship, and the lure of profit are all a person's "cold season." To hold to one's benevolence and righteousness under pressure does not mean feeling no fear or pain at all, but that pain cannot take away one's resolve. The firmness of virtue lies here, and the yielding of virtue lies here too: firmness keeps one unbending; yielding lets one endure prolonged hardship without breaking.
That Yan Hui could go three months without departing from benevolence was already highly praised by the Master; his other disciples could reach it only for a day or a month at a time, showing how difficult it is to sustain benevolent virtue continuously. A person can occasionally have a benevolent heart; the difficulty lies in letting benevolence become a stable way of life. Endurance requires the closeness that being easy to know produces: not forcibly suppressing oneself, but the heart truly drawing close to benevolence. Only when this closeness runs deep can outward temptation fail to easily move it.
Master Zeng, at the point of death, had his disciples uncover his hands and feet, describing a lifetime of guarding himself with trepidation, as though facing a deep abyss, as though treading on thin ice. The endurance of virtue is not easy self-satisfaction, but is so often accompanied by reverent caution. The more a person believes he has already succeeded, the more easily he indulges himself; the worthy person, knowing that virtue and achievement are boundless, never dares to grow careless throughout his life. That Qian's vigor never ceases and Kun's depth knows no bound both mean that one cannot stop simply because a single task has been completed.
The Most High said, "Knowing contentment brings no disgrace; knowing when to stop brings no danger; thereby one can endure long." Endurance also depends on knowing when to stop. If a person, after achieving success, becomes insatiably greedy, his virtue and achievement will be destroyed by his own expansion; if, even amid great renown, he still contends for more, those close and trusting to him will turn to resentment and departure. The revolving of sun and moon has its retreat; the coming and going of cold and heat has its alternation; the worthy likewise knows when to advance and when to withdraw. Endurance is not eternal expansion, but the ability to draw back and preserve oneself at the proper time.
State institutions likewise must be tested by endurance. Severe punishment and harsh law may check disorder in the short term; whether they can endure depends on whether the people's hearts are at peace, whether officials can hold to their duty, and whether resources can be sustained. If a policy exhausts the people's strength in exchange for momentary achievement, it lacks the virtue of the worthy. The endurance of virtuous governance does not mean the institution is never adjusted, but that its adjustments never depart from the fundamental root of nurturing the people, fairness, and sincerity.
