Arjun Vishaad Yog-Bhagavad Gita Chapter 1 [Observing the Armies on the Battlefield of Kurukshetra]
Arjun Said > Shaloka: 46
I would consider it better for the sons of Dhrtarastra to kill me unarmed and unresisting, rather than to fight with them.
It is the custom–according to ksatriya fighting principles–that an unarmed and unwilling foe should not be attacked. Arjuna, however, in such an enigmatic position, decided he would not fight if he were attacked by the enemy. He did not consider how much the other party was bent upon fighting. All these symptoms are due to soft-heartedness resulting from his being a great devotee of the Lord.
