Mencius - Book 3, Part 1, Chapter 2B

The prince said again to Zan Yû, 'Hitherto, I have not given myself to the pursuit of learning, but have found my pleasure in horsemanship and sword-exercise, and now I don't come up to the wishes of my aged relatives and the officers. I am afraid I may not be able to discharge my duty in the great business that I have entered on; do you again consult Mencius for me.' On this, Zan Yû went again to Tsâu, and consulted Mencius.

Mencius said, 'It is so, but he may not seek a remedy in others, but only in himself. Confucius said, "When a prince dies, his successor entrusts the administration to the prime minister. He sips the congee. His face is of a deep black. He approaches the place of mourning, and weeps. Of all the officers and inferior ministers there is not one who will presume not to join in the lamentation, he setting them this example. What the superior loves, his inferiors will be found to love exceedingly. The relation between superiors and inferiors is like that between the wind and grass. The grass must bend when the wind blows upon it." The business depends on the prince.'

Zan Yû returned with this answer to his commission, and the prince said, 'It is so. The matter does indeed depend on me.' So for five months he dwelt in the shed, without issuing an order or a caution. All the officers and his relatives said, 'He may be said to understand the ceremonies.' When the time of interment arrived, they came from all quarters of the State to witness it. Those who had come from other States to condole with him, were greatly pleased with the deep dejection of his countenance and the mournfulness of his wailing and weeping.
