Those who are blind, apaśyatām ātma-tattvam, blind about understanding the soul, they have got many thousands and thousands of matter, subject matter for hearing—useless. The human life is meant for understanding what I am and what is God, what is my relationship with God. That is the real purpose of human life. Otherwise, "Where is food?" "Where is shelter?" "Where is service?" "Where is sex?" these are the inquiries of the animals only. The hog also inquiring, "Where is stool? Where is stool? Where is stool?" The stool-eater, he is also working hard, "Where is stool? Where is stool? Where is stool?" Do you think that is very creditable task, to work hard day and night for finding out where is stool? This is hog's business.
So at the present moment, the civilization is going on, "Where is food?" "Where is apartment?" "Where is sex?" and "Where is defense?" So these are the inquiries of the animals. They are also searching, "Where is food?" "Where is shelter?" "Where is sex?" and "Where is defense?" Āhāra-nidrā-bhaya-maithunaṁ ca sāmānyam etat paśubhir narāṇām (Hitopadeśa 25). The human life is meant for inquiring, "Where is God?" That is human life. Not "Where is stool?" That is hog's business. So we should not encourage this hog civilization. Hog civilization is to work hard day and night to find out where is food, where is shelter, where is sex and where is defense. Wrong type of civilization. The human civilization means "Where is Brahman, the Absolute Truth?" Athāto brahma jijñāsā. That is the Vedānta-sūtra. "Where is God?" "What I am?" These are the inquiries.
So personally the Supreme Personality of Godhead, Kṛṣṇa, is teaching that the soul transmigrates. Tathā dehāntara-prāptiḥ. Dehāntara-prāptiḥ means transmigrating from one body to another. Dhīras tatra na muhyati (BG 2.13). Those who are dhīra, sober, full of knowledge, they are not bewildered, they are not perturbed. Because he knows that, "My father or brother, everything, is said to be dead, it is . . . he is not dead." This gross body, this coat, coating of the body, has stopped. It is old enough, or by some reason it is torn, it is no longer usable. Therefore the soul has left this gross body and, being carried by the subtle body—mind, intelligence, ego—he has gone to accept another gross body. This is transmigration of the soul. Tathā dehāntara-prāptiḥ (BG 2.13).
Just like the mother knows, "My baby was on my lap. Now as a boy he is running." So she is not lamenting. She knows, "That is my child, same child. Simply he has transformed the body." Similarly, we should not lament when a man dies. We should not lament. Because Arjuna was thinking in terms of the body, in the battlefield he was bewildered whether . . . because the other side were all relatives. Therefore Kṛṣṇa is giving the knowledge that, "Don't think that your father or your grandfather or your brother, they will be finished. No. They will be simply . . . if you kill, they will simply be transferred to another body. Better you consider that your grandfather is possessing now an old body; if you kill your grandfather in the battlefield . . ."
Because formerly the war was declared not whimsically. The war was also religious war. So in the religious war, a kṣatriya . . . the kṣatriyas were fighting, not the śūdras, not the brāhmins, not the vaiśyas. There was a caste for fighters. Not like this, where a śūdra is elected as president, he is not fighting, he is in a safe place, and he is simply directing, "You go and fight. Let me see how you are fighting." No. The king, the kṣatriya, he will come forth in the front of fighting. That was fight.
If the king is killed by the opposite party, then it is declared that they are victorious—no more fight, no more unnecessarily killing other persons. The aim was to kill the king. The king was on the front. The other party, he was also in front. The king is fighting with king, and the soldiers are fighting with soldier. So when the king is killed, then the other party becomes victorious. That was the process of war, not that releasing atomic bomb from the sky and kill so many innocent persons. No. That is not war.
So war, if it is fought on principle, on religious principle, that is called dharma-yuddhi. That is not prohibited. But this killing process, unnecessarily, innocent men, that is not dharma-yuddhi. That is irregular fighting. That kind of war is not sanctioned by the Vedas.
