śreyānsvadharmo viguṇaḥ paradharmātsvanuṣṭhitāt |
svadharme nidhanaṃ śreyaḥ paradharmo bhayāvahaḥ || 35 ||

Those men who always follow this opinion of mine with faith and without cavil attain to final emancipation even by work. But they who cavil at and do not follow this opinion of mine, know, that, bereft of all knowledge and without discrimination, they are ruined. Even a wise man acts according to his own nature. All living beings follow (their own) nature. What then would restraint avail? The senses have, as regards the objects of the senses, either affection or aversion fixed. One should not submit to these, for they are obstacles in one's way. One's own duty, even if imperfectly performed, is better than being done by other even if well performed. Death in (performance of) one's own duty is preferable. (The adoption of) the duty of another carries fear (with it).
