वरं स्वधर्मो विगुणो न पारक्यः स्वनुष्ठितः । परधर्मेण जीवन् हि सद्यः पतति जातितः ॥ ९७ ॥
It is better (to discharge) one’s own (appointed) duty incompletely than to perform completely that of another; for he who lives according to the law of another (caste) is instantly excluded from his own.
A Vaisya who is unable to subsist by his own duties, may even maintain himself by a Sudra’s mode of life, avoiding (however) acts forbidden (to him), and he should give it up, when he is able (to do so).
But a Sudra, being unable to find service with the twice-born and threatened with the loss of his sons and wife (through hunger), may maintain himself by handicrafts.
