The Great Learning Passage 12

What is meant by "The making the whole kingdom peaceful and happy depends on the government of his state," is this: When the sovereign behaves to his aged, as the aged should be behaved to, the people become filial; when the sovereign behaves to his elders, as the elders should be behaved to, the people learn brotherly submission; when the sovereign treats compassionately the young and helpless, the people do the same. Thus the ruler has a principle with which, as with a measuring square, he may regulate his conduct. What a man dislikes in his superiors, let him not display in the treatment of his inferiors; what he dislikes in inferiors, let him not display in the service of his superiors; what he hates in those who are before him, let him not therewith precede those who are behind him; what he hates in those who are behind him, let him not bestow on the left; what he hates to receive on the left, let him not bestow on the right. This is what is called "The principle with which, as with a measuring square, to regulate one's conduct." In the Book of Poetry, it is said, "How much to be rejoiced in are these princes, the parents of the people!" When a prince loves what the people love, and hates what the people hate, then is he what is called the parent of the people. In the Book of Poetry, it is said, "Lofty is that southern hill, with its rugged masses of rocks! Greatly distinguished are you, O grand-teacher Yin, the people all look up to you." Rulers of states may not neglect to be careful. If they deviate to a mean selfishness, they will be a disgrace in the kingdom.
