Arjuna is asking the Supreme Personality of Godhead that "You teach me." That is perfect teaching. If you learn something from Kṛṣṇa, or from His representative, that is perfect. That is perfect knowledge. All other knowledge that you gather, that cannot be perfect. Because unless you are perfect, how you can give perfect knowledge? So every one of us is imperfect. Because we have got imperfect senses. So with imperfect knowledge...
Just like the so-called scientists, philosophers, they propose their theories; "I think," "It may be like this," "Perhaps..." These are not knowledge. These are all nonsense. You must speak definitely if you know. Just like the śāstra says: jalajā nava-lakṣāṇi. Definitely. Nine hundred thousand species of life within the water. Why? You could say: "About nine lakhs." No. Nine lakhs. Not about. More or less. No. Not like that. That is knowledge. That is perfect... Jalajā nava-lakṣāṇi sthāvarā lakṣa-viṁśati. And the trees, plants, they are two millions. Never says: "approximately." "Maybe," "perhaps." No. This is all nonsense. We don't accept such knowledge. So... But the, in the material world, these things are going on. Any rascal will give some theory. That will be accepted and he'll be offered Nobel Prize.
So that is condemned in the Śrīmad-Bhāgavatam: śva-viḍ-varāha-uṣṭra-kharaiḥ saṁstutaḥ puruṣaḥ paśuḥ. So according to Bhāgavata direction, these Nobel Prize winners are exactly like dogs, camels, hogs, śva-viḍ-varāha-uṣṭra and asses. And they are praised by similar animals. That's all. The Nobel Prize winner and the Nobel Prize giver. Both of them are like dogs hogs animal and asses. That's all. This is a fact. They... If, if a person has written some theory, evolution of chemicals, and all rubbish things, it is very nice thing for the so-called dogs and camels, but those who have got eyes to see, one who has heard from Kṛṣṇa, he'll understand this is nonsense. How, from chemical, you can produce life? When he's asked: "Well, sir, if I give you these chemicals, can you produce life?" Immediately he says: "That I cannot say." Why?
It is actually happening. In California University. One big professor, came, lecture, and he said that:. "By combination of these four chemicals, life has begun." So one of our students, he's also doctor in chemistry, he asked him immediately: "Sir, if I give you all these chemicals, whether you can produce life?" His answer was; "That I cannot say." Why? "That I cannot say." Then why you are proposing all this nonsense? If you do not know definitely... "No, we are trying." "In future..." This is going on. "In future." But in the common saying: "Trust no future, however pleasant." Why future? Now, what you have learned, speak that.
Therefore Arjuna is asking not to a third-class so-called philosopher and chemist and economist, but to Kṛṣṇa. Kṛṣṇa. Because whatever answer Kṛṣṇa will give, that is fact. And śāstra means the things which have been spoken by Kṛṣṇa. That is śāstra. And guru means who speaks... Guru means who speaks on behalf of Kṛṣṇa. Sādhu-śāstra-guru. This is called. So Kṛṣṇa is asked. And the answer for Kṛṣṇa, which He gives, that is final. No experiment. No "future." Whatever answer He gives, that is final. Otherwise, why people read Bhagavad-gītā so carefully? Not now. Thousands of years. Thousands of years. Not only in India, in other countries also. So answers, real answers are there.
So this chapter, thirteenth chapter, is very important chapter. So many rascals are there. They're talking so many things. But if you want real answer, that is described by Kṛṣṇa to the six questions, Kṛṣṇa immediately answers in nutshell.
The first question was: prakṛtiṁ puruṣaṁ caiva. Prakṛtiṁ puruṣam will be answered later on. The first answer He gives: idaṁ śarīraṁ kaunteya kṣetram ity abhidhīyate (BG 13.2). You want to learn what is the field of activities. Field of activities is not the football ground. This body is field of activities. When I desire to play in the football ground, then I go to the football ground. But real desire is manufactured within. Idaṁ śarīram. We, we are having different types of body because we want to work differently. That is the plan. I ask so many people. They say: "God has created this world." That's fact. But as soon as we ask, "Why He has created this earth? Why He has created this universe? What is the purpose?" they cannot answer. They cannot give any reply. Because they do not know, imperfect knowledge. But anything you do, anything... Especially...
Suppose if you construct a very nice house. So I can ask you: "What is the purpose of constructing this nice house?" You will say: It is for purpose." Either we shall reside, or rent it. "It is meant for residential purpose." Similarly why this cosmic manifestation, this universe... Not only one universe, millions of universes. Material world is also not very small. Material world is only one-fourth manifestation of the whole creation. And that one-fourth... Ekāṁśena sthito jagat (BG 10.42). Kṛṣṇa says: "The whole material world is only one-fourth creation." What is that one-fourth creation? That is replied in the Brahma-saṁhitā: yasya prabhā prabhavato jagad-aṇḍa-koṭi (Bs. 5.40). Jagad-aṇḍa-koṭi. When Kṛṣṇa, you have seen Kṛṣṇa's, what is called? Aureum?
Prabhupāda: Auram, yes. So that is prabhā, Kṛṣṇa's prabhā. So just like the sun has got a shining, similarly Kṛṣṇa has got. So it is borrowed from Kṛṣṇa's shine. So yasya prabhā prabhavato jagad-aṇḍa-koṭi (Bs. 5.40). Jagad-aṇḍa means these universes. There are millions, koṭi. And each universe... Jagad-aṇḍa-koṭi. Yasya prabhā prabhavato jagad-aṇḍa-koṭi-koṭiṣv aśeṣa-vasudhādi-vibhūti-bhinnam (Bs. 5.40). And each universe there are innumerable planets. This is material creation. So how we can know about this material creation? But we can know from Kṛṣṇa. Because He knows everything. Because everything is manufactured from Him. Mattaḥ sarvaṁ pravartate. So we have to know like that. Janmādy asya yataḥ (SB 1.1.1). So He can speak perfectly what is the plan, the, of this creation, creation of the universal, universe. The plan is that we living entities, kṣetra-kṣetra-jña... Kṣetra means this body. Idaṁ śarīraṁ kṣetram ity abhidhīyate. It is said: idaṁ śarīraṁ kaunteya kṣetram ity abhidhīyate (BG 13.2). "You have asked the question: 'What is kṣetra, field of activities, and who is the knower of this field,' so I answer: idaṁ śarīraṁ kaunteya kṣetram (BG 13.2). This body is the field of activities."
So this material world is created by God to give us facility to work as I desire. But I must have the jurisdiction of my work. That is the... Jurisdiction my work. Just like the agriculturist, they have got their own land, demarcated. This much, my land, this much, his land, this much..." And he works, tills the field, produces food grain, according to his capacity. Similarly Kṛṣṇa has given us different fields of activities. That is this body. Idaṁ śarīraṁ kaunteya kṣetram (BG 13.2). Idaṁ śarīram. So from the śarīra, we expand many other things. That also becomes kṣetram.
So this is the purpose of creation. Kṛṣṇa gives us full facility. I want to work in this way. All right, you work. Kṛṣṇa says that you don't work. This will not make you happy. You are asking Me facilities to fulfill your desire under certain condition. That you may have from Me. I can give you. But you'll never be happy." That is Kṛṣṇa's order. You'll never be happy. How I shall be happy? Sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). You'll be happy only by this process. Simply by this process. If you manufacture, by your fertile brain, that: "I shall be happy in this way and that way," you'll never be happy. If you want to be happy at all, then this is My instruction: sarva-dharmān parityajya mām ekaṁ śa... (BG 18.66). Kṛṣṇa is repeatedly saying this to everyone.
