Shu-sun Wu-shu having spoken revilingly of Chung-ni, Tsze-kung said, 'It is of no use doing so. Chung-ni cannot be reviled. The talents and virtue of other men are hillocks and mounds which may be stepped over. Chung-ni is the sun or moon, which it is not possible to step over. Although a man may wish to cut himself off from the sage, what harm can he do to the sun or moon? He only shows that he does not know his own capacity.
