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 creator . . . creation of the universes, 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, "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 of my work. Just like the agriculturist, they have got their own land, demarcated: "This much your land, 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.
