Fu Xinsi
When entering the dance, the king holds the dry and the halberd and takes the dance position. The king is on the east side, wearing a crown and holding the dry, and leads his ministers to enjoy the emperor's corpse. Therefore, when the emperor sacrifices, he enjoys it with the world; when the princes sacrifice, he enjoys it with the whole country. The emperor wore a crown and held the pillars of heaven, and led his ministers to entertain the emperor's corpse. This is the meaning of the inner music. There are three levels of sacrifice: among the offerings, nothing is more important than being naked, nothing is more important than singing, and nothing is more important than "Wu Su Ye". This is the way of Zhou. All three ways are used to borrow from the outside to increase the ambition of the gentleman, so they advance and retreat with the ambition; if the ambition is light, it is also light, and if the ambition is heavy, it is also heavy. If one's ambition is light and seeks external weight, even a sage cannot obtain it. Therefore, when a gentleman offers sacrifice, he must sacrifice himself, so as to make it clear that it is heavy. He should follow the etiquette, worship the three levels, and offer it to the emperor's corpse. This is the way of the sage. There is a 馂 in sacrifice; 馂 is the end of the sacrifice, which must be known. Therefore, the ancients said: "A good end is like the beginning." 馂 is just that. Therefore, the ancient gentlemen said: "The corpse is also the remnant of the ghosts and gods, and it is a benevolent method, which can be used to observe politics." Therefore, when the corpse is made, the king and the ministers are made to make it. When the king stands up, the senior officials are made to make it. The ministers are made to make it. The remnants of the king. The senior officials are made to make it. Eight scholars are made to make it. The lower officials are made to make it. The remnants of the nobles. The scholars are made to stand up, each holding their own utensils and go out, and they are laid out under the hall. The officials come in and clear them, and the lower officials are made to make it. The lower officials are made to make it. The way of making it is to change the number of people, so as to distinguish the noble and the humble, and to promote the image of benevolence. Therefore, four 簋黋 of millet are used to show that it is being cultivated in the temple. The temple is a symbol of the inner court. The sacrifice is the greatest benefit. Therefore, if there is a great benefit in the upper part, the benefit will surely reach the lower part, but the upper part will be the first and the lower part will be the last. It is not that the upper part is overburdened and the lower part is cold and hungry. Therefore, if there is a great marsh above, the people will wait for it below, knowing that the benefit will surely come, and they can see it from the taro. Therefore, it is said: "You can observe the politics."
