। ॥ ४० ॥
In plain words
A son can turn out to be the very one who destroys his father, mother, and kin — born only to break their hearts. He waits for his own father's death, hoping to become master of the property.
Close to the Sanskrit
A son may be born to become a destroyer of father, mother, and kin, a source of grief for the mind; the son looks forward to his own father's death, for the sake of becoming master over wealth and the like.
