अथ चेत्त्वमिमं धर्म्यं सङ्ग्रामं न करिष्यसि। ततः स्वधर्मं कीर्तिं च हित्वा पापमवाप्स्यसि॥
atha chet tvam imam dharmyam sangramam na karishyasi tatah svadharmam kirtim cha hitva papam avapsyasi
Translation
But if you do not fight this righteous war, you will abandon your duty and honor, and incur sin.
Commentary
Krishna warns that not fighting has consequences too. Running from duty does not avoid sin - it creates sin. Arjuna cannot escape his responsibility by simply refusing to act.
