श्रेयान्स्वधर्मो विगुणः परधर्मात्स्वनुष्ठितात्।
स्वधर्मे निधनं श्रेयः परधर्मो भयावहः।।3.35।।
।।3.35।। सम्यक् प्रकार से अनुष्ठित परधर्म की अपेक्षा गुणरहित स्वधर्म का पालन श्रेयष्कर है स्वधर्म में मरण कल्याणकारक है (किन्तु) परधर्म भय को देने वाला है।।
In this verse Lord Krishna is emphasising the fact that one should perform the duties one is authorised to do according to ones station and rank in society. Arjuna was a royal prince educated and trained by the strength of his might to uphold and protect dharma or righteousness and although war enacts terrible suffering it was necessary and was appropriate for Arjuna to engage in it.
