Mencius - Book 1, Part 2, Chapter 16B

The officer Yo-chang entered the court, and had an audience. He said, 'Prince, why have you not gone to see Mang K'o?' the duke said, 'One told me that, on the occasion of the scholar Mang's second mourning, his observances exceeded those of the former. It is on that account that I have not gone to see him.'

'How is this!' answered Yo-chang. 'By what you call "exceeding," you mean, I suppose, that, on the first occasion, he used the rites appropriate to a scholar, and, on the second, those appropriate to a great officer; that he first used three tripods, and afterwards five tripods.' The duke said, 'No; I refer to the greater excellence of the coffin, the shell, the grave-clothes, and the shroud.' Yo-chAng said, 'That cannot be called "exceeding." That was the difference between being poor and being rich.'

After this, Yo-chang saw Mencius, and said to him, 'I told the prince about you, and he was consequently coming to see you, when one of his favorites, named Tsang Ts'ang, stopped him, and therefore he did not come according to his purpose.'

Mencius said, 'A man's advancement is effected, it may be, by others, and the stopping him is, it may be, from the efforts of others. But to advance a man or to stop his advance is really beyond the power of other men. My not finding in the prince of Lû a ruler who would confide in me, and put my counsels into practice, is from Heaven. How could that scion of the Tsang family cause me not to find the ruler that would suit me?'
