Here Arjuna exclaims that he cannot foresee any benefit from slaying his own kinsman in battle. In the Vedic scriptures it is revealed that in this world 2 types of living entities are automatically granted entrance to the heavenly planets: one being the renunciate who is disciplined in the practice of yoga and the other is the warrior slain in battle. So Arjunas arguement is that although there is provision for the slain, there is no declaration of any merit for the slayer.
