Arjuna was hesitating to fight, "How can I kill my nephew, my brother, my grandfather," and so on, so on. So Kṛṣṇa was instructing him that, "It is your duty. As a kṣatriya, when there is battle, you should fight. You should not deviate from your duty." That was the conversation was going on. But Arjuna was thinking only in terms of this body. "He is my grandfather. He is my brother. He is my countryman. He is my this." Why? Because they have got some bodily relation.
You are thinking one boy here, because he is Australian, you are thinking more intimate relationship with him, and because I am Indian, you may not think more . . . in such intimacy. Because the bodily connection is there. But Kṛṣṇa said that, "This is not very intelligent knowledge." Gatāsūn agatāsūṁś ca. A person who does not lament for this body, he is actually learned. Gatāsūn agatāsūṁś ca nānuśocanti paṇḍitāḥ (BG 2.11). Paṇḍita means learned scholar. So either this body is in living condition or it is in dead condition, a paṇḍita, a learned scholar, one who knows things as they are, he does not take care of this body. Not take care actually; he does not think very seriously about this body. That was the answer given by . . .
Because this body is, after all, a lump of matter. Actually, so long the soul is there, it is moving. It is growing or changing bodies or so many importance is there due to . . . therefore, unless we come to this understanding that, "I am not this body. I am spirit soul," ahaṁ brahmāsmi, there is lack of knowledge. That is being instructed by Kṛṣṇa.
