Musar על ויקרא 10:6

ובגדיכם לא תפרומו . The reason that the priests must not rend their garments (10,6) is connected with their function as a sign of honor and dignity. We can apply the treatment to be accorded to these garments to the treatment we must accord to our bodies. The body is the garment of the soul. How much more insulting would it be to the soul if our body, its showpiece, would be torn, i.e. would bear signs of the sins we have committed!
