उत्रवत्दंष्ट्रोरगन्यायः

As a serpant deprived of its fang is harmless, so also a wicked man, who has lost his power, a robber, who has become weak and infirm, or a voluptuous debauch in his old age, can do no harm to any one. The maxim teaches that the evil propensities lose their force with the decline of physical strenght.
