Better is one's own duty, though devoid of merit than the duty of another well discharged. Better is death in one's own duty; the duty of another is fraught with fear (is productive of danger).
He who does actions, offering them to Brahman, and abandoning attachment, is not tainted by sin, just as a lotus-leaf is not tainted by water.
Better is one's own duty (though) destitute of merits, than the duty of another well performed. He who does the duty ordained by his own nature incurs no sin.
Further, having regard to thy own duty, thou shouldst not waver, for there is nothing higher for a Kshatriya than a righteous war.
Therefore without attachment, do thou always perform action which should be done; for by performing action without attachment man reaches the Supreme.
The Bhagavad Gita calls your own path your dharma — and insists it is better to follow it imperfectly than to perfect someone else's. These verses are about finding and trusting your own work.
