The Battle of Kurukṣetra, it was finished within eighteen days. There is no use of prolonging the war unnecessarily. If the chief man is killed, then war is finished. Therefore Kṛṣṇa is advising Arjuna that "Suppose your grandfather on the other side dies, so where is the cause of lamentation? He's old man. He will get another, new body. So you should be rather happy that your old grandfather is going to have a new body." Jātasya hi dhruvo mṛtyuḥ. "And everyone will die. You die today or tomorrow, or, say, fifty years after. You have to die. It is as sure as death. So why should you deviate from your duty? You are a kṣatriya. Your duty is to fight. Why you are afraid of being dead, or killing others? This is your duty."

So the body was not existing before. And it will not exist after death. So in the via media, if the manifestation of body is there, so why it should be the object of lamentation? In this way, Kṛṣṇa is trying to convince Arjuna that he should act as kṣatriya and perform his duty. A kṣatriya is profited, either dead or alive. That will be explained. Because in a, in a fighting, I mean to say, real religious fighting, on principle, it is, a kṣatriya is not responsible for killing. Just like in sacrificial ceremony, if the animal is killed, the brāhmaṇa is not responsible for killing an animal. So because it is duty, it is ordained by the śāstras, therefore they are not ordinary killing. Avyakta-nidhanāny eva tatra kā pari... "It was nonmanifested before, and it will become nonmanifested again. So why should you lament for the via media?"
