《孔子家语·冠颂》
天下没有生下来就高贵的，故而冠礼一定要在祖庙里举行，用裸享的礼节来进行，用钟磬之乐加以节制，这样可以使加冠者感到自己的卑微而更加尊敬自己的祖先，以表示自己不敢擅越祖先的礼制。 
天下无生而贵者，故也行冠事必于祖庙，以裸享之礼以将之，以金石之乐节之，所以自卑而尊先祖，示不敢擅。 
There is nobody who is born with noble status in this world, therefore the capping ceremony must be held in the ancestral temple, and carry out the rituals for presenting sacrificial meat, and control with bell and chime music, this can make the person putting on the cap feel their own inferiority and thus respect their ancestors even more, to show that they dare not overstep the rituals of their ancestors.
