《礼记·祭义》
而当国君祭祀，我们作为宾客去参加时，反馈之礼完毕，奏起了音乐，荐上了牲体，按照礼乐的次序，大夫百官济济一堂，这时君子便可以仪态从容，神情矜持，这时怎么能像与神明交接时那样恍恍惚惚呢?说话岂能一概而论?
反馈，乐成，荐其荐俎，序其礼乐，备其百官。君子致其济济漆漆，夫何慌惚之有乎？夫言，岂一端而已？
But when the emperor sacrifices, and we attend as guests, after the return ceremony is completed, the music is played, and the animals are offered. According to the order of the etiquette and music, the great officials and hundreds of officials are gathered together. At this time, the gentleman can be graceful and serious. How can it be like the time when he communicates with the gods? Can speech be generalized?
