Bhagwad Gita
Chapter 3, Verse 35
श्रेयान्स्वधर्मो विगुणः परधर्मात्स्वनुष्ठितात्।
स्वधर्मे निधनं श्रेयः परधर्मो भयावहः।।3.35।।
It is far better to discharge one's prescribed duties, even though they may be faulty, than another's duties. 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.
