Sreyan sva-dharmo vigunah para -dharmat sv-anusthitat
sva-dharme nidhanam sreyah para-dharmo bhayavahah
(Text 35, Ch 3, Karma Yoga)
Meaning: 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.
