《淮南子·汜论训》
礼乐是圣人制定的，并不是圣人受礼乐的限制；治理国家虽然有常规，但必须以利民为根本；政令教化虽然有常法，但必须以切实有效为最好。
治国有常，而利民为本；政教有经，而令行为上。
Rites and music are established by the sages, and the sages are not restricted by rites and music; although governing the country has regular practice, it must be based on benefiting the people; although government orders and education have established methods, they must be best in terms of being effective.
