Prabhupāda: Niṣkiñcana means a great personality who has become completely freed from all material consciousness. He is called mahīyasām. He is also great, the great soul. So unless one takes shelter of the lotus feet or the dust of the lotus feet of a great personality who has no material affection, nobody can understand what is God. Naiṣāṁ matis tāvad urukramāṅghriṁ spṛśaty anarthāpagamo yad-arthaḥ (SB 7.5.32). As soon as one understands the spirit soul and the supreme soul... That can be understood only when one is taken shelter of a great personality freed from material contamination. This is the version of Śrīmad-Bhāgavatam. Otherwise, it is amazement. To understand about soul is amazement. To understand about God is amazement. So Vedic injunction is therefore that if you are at all serious to understand tad vijñānam, that science, transcendental science... Tad vijñānārthaṁ sa gurum evābhigacchet (MU 1.2.12). The Veda says, "Then you must find out a bona fide spiritual master." Tad vijñānārtham, if you are seriously interested. Go on.
Devotee: 30: "O descendant of Bharata, he who dwells in the body is eternal and can never be slain. Therefore you need not grieve for any creature (BG 2.30)."
Prabhupāda: Now, after putting forward all definitions and arguments from different angles of vision, of different philosophers, thesis, now Kṛṣṇa concludes, "My dear Arjuna, take it for certain that the soul within is eternal." So because we are in Kṛṣṇa consciousness, even if we do not understand what is the constitutional position of the soul, here, because Kṛṣṇa says, we should accept it. This is called paramparā. Evaṁ paramparā-prāptam (BG 4.2), disciplic succession. What does He say? Yes. The same verse repeat.
Devotee: 30: "O descendant of Bharata, he who dwells in the body..."
Prabhupāda: "He who dwells in the body." He began this instruction that deha, dehī—the body and the proprietor of the body or the resident of the body. Just like this hall, and we are a resident of this hall. We are different. We are not this hall. This lecture room, we are within this lecture room, but that does not mean that we are or I am or you are this lecture room. Similarly the soul dwells in this body. The body is changing but the soul is not changing. That was the beginning of conversation with Arjuna after his surrendering unto Kṛṣṇa as disciple. And again He concludes in that way, that the soul... "Take it from Me, because you have accepted Me as your spiritual master." This is the significance. If you accept somebody as spiritual master, you have to accept whatever he says. Otherwise there is no need. But if you cannot understand, you can inquire sincerely. That is not barred. But you have to accept. So Kṛṣṇa says, conclusion, what is that? That "Within this body..." What is that?
Devotee: "He who dwells in the body is eternal..."
Prabhupāda: "He who dwells within this body is eternal." Then?
Devotee: "...and can never be slain."
Prabhupāda: "And can never be slain." Because it is already described that soul cannot be burned, soul cannot be moistened, soul cannot be dried up, soul cannot be killed, soul cannot be cut into pieces. So many things. Just opposite of matter. Any material thing you take, even stone, iron, it can be burned, it can be cut into pieces, it can dry up, and so many things, all applicable to the matter. But so far the spirit soul is concerned, it is just the opposite. Therefore the conclusion is there, na hanyate hanyamāne śarīre (BG 2.20). Even after this body is annihilated the soul remains eternal. Just like if somebody comes and drives us out of this room, that does not mean that I am finished. I shall go and take shelter of another room. Similarly, when the soul, when the body is killed or annihilated by nature or by force, the soul takes shelter of another body. That is the conclusion. Go on.
Devotee: 31: "Considering your specific duty as a kṣatriya you should know that there is no better engagement for you than fighting on religious principles, and so there is no need for hesitation (BG 2.31)."
Prabhupāda: So here fighting is a matter of duty. That is the kṣatriya spirit. Fighting is not killing. Because people have no idea what is the soul, therefore they think that stopping war will help us in peaceful condition of the society. There are so many troubles so long this body is there. War is one of the items. Even war is stopped, there is no question that people will live forever. No. That is not the law of nature. Duḥkhālayam aśāśvatam (BG 8.15). This life, the problem is how to stop our contact with this material body That is the problem. Not that these general people, they are thinking, "If war, there is no war, then we shall be very happy." How you'll stop your war with māyā? Māyā has declared war with you, or you have declared war with māyā. Daivī hy eṣā guṇamayī mama māyā duratyayā (BG 7.14). The māyā, the material nature is enforcing, "Why you are closing this door?" "Oh, because it is very cold outside." Who is forcing? Immediately there will be cold, immediately there will be fog, immediately there will be excessive heat, immediately there may be earthquake. How you can stop it? So they simply think... Just like innocent child, they are concerned with the immediate problem. But sane man is concerned with the ultimate problem. So our ultimate problem is not this war. The ultimate problem is repetition of birth and death. That is ultimate problem, how to stop this. That is the problem. So Kṛṣṇa says that "This is useless lamentation, that you do not wish to fight. It is the concluded fact that even your grandfather or relatives die, they will continue as soul. You have to execute your duty. You cannot deviate from your duty." Go on.
