न चैतद्विद्मः कतरन्नो गरीयो यद्वा जयेम यदि वा नो जयेयुः। यानेव हत्वा न जिजीविषामस्तेऽवस्थिताः प्रमुखे धार्तराष्ट्राः॥
na chaitad vidmah kataran no gariyo yad va jayema yadi va no jayeyuh yan eva hatva na jijivisamas te'vasthitah pramukhe dhartarashtrah
Translation
We do not know which is better for us - to conquer them or be conquered by them. The very sons of Dhritarashtra, after killing whom we would not wish to live, stand before us.
Commentary
Arjuna admits his total confusion - he cannot determine what is right. This honest admission of not knowing is actually the prerequisite for receiving true knowledge from a guru.
