Sacrifice is a great thing, and it is a preparation for everything. Is it the root of education to follow the preparation? Therefore, the teaching of a gentleman is to teach people to respect their rulers and elders externally and to be filial to their parents internally. Therefore, when a wise ruler is above, all ministers obey; when the ancestral temples and the altar of the country are respected, the descendants are obedient and filial. Do your best and be upright in your righteousness, and the teaching will come into being. Therefore, when a gentleman serves his ruler, he must practice it himself. What he does not like in his superiors, he will not use his subordinates; what he hates in his subordinates, he will not serve his superiors; if he does not do it to others, he will do it to himself, which is not the way of teaching. Therefore, the teaching of a gentleman must start from its root and follow the ultimate, and sacrifice is it? Therefore, it is said: sacrifice is the root of education. There are ten relationships in sacrifice: the way to serve ghosts and gods, the righteousness between the ruler and the minister, the relationship between father and son, the distinction between the noble and the humble, the killing of relatives and strangers, the bestowal of titles and rewards, the difference between husband and wife, the balance of political affairs, the order of the old and the young, and the relationship between superiors and subordinates. These are the ten relationships.
