When by the heat of summer his body sweats and is covered with dirt and dust, a wise monk should not lament his loss of comfort. (36)
He should bear (all this), waiting for the destruction of his Karman, (and practising) the noble, excellent Law; he should carry the filth on his body till he expires. (37)
