Bhagavad Gita Chapter 3.35
śreyān sva-dharmo viguṇaḥ
para-dharmāt sv-anuṣṭhitāt
sva-dharme nidhanaḿ śreyaḥ
para-dharmo bhayāvahaḥ
Translation
It is far better to discharge one’s prescribed duties, even though faultily, than another’s duties perfectly. Destruction in the course of performing one’s own duty is better than engaging in another’s duties, for to follow another’s path is dangerous.
