So this is very good example, that idaṁ śarīraṁ kṣetram. He has given, God has given you a piece of land, this body. Now you work. You make your future with this body. Karmaṇā... Because the body is produced according to my karma. Otherwise, why there are so many varieties of body? We are all human beings. Everyone, we are, we possess two hands, two legs. Still, the bodies are different. We don't find anybody's body is exactly equal to the other. No. Because we have got different mentality. Every one of us, we are individual soul; we have got different mentality, different propensities, different ideas. So in this way we have got different bodies. This is the science.
Science, they are searching out so many things, but they do... Why they cannot explain that why there are varieties of body. Why not exactly equal human being exactly of the same feature, same...? Just like we do some... In mold, the, all the dolls come out of the same body. It is not like that. For each and every living entity, Kṛṣṇa has to prepare a different type of body. Therefore we have got different types of body according to karma.
So this is knowledge, that "I have got this body as field." As one gets the land for cultivating his food grains, according to his labor, according to his choice, similarly, we have got this field of activity. Now we can make our future good or bad according to our choice. Idaṁ śarīraṁ kaunteya kṣetram iti abhidhīyate (BG 13.2). This is called kṣetra, working land.
Just like father gives some capital to the son: "You do some business." Now, you lose the money or increase it hundred times; that depends on you. Similarly, Kṛṣṇa has given us. We wanted to enjoy this material world, and Kṛṣṇa has given us. The first beginning body is Brahmā, very exalted body. But on account of our abominable activities, from Brahmā, we come down to become the worm of stool. This is called karma, kṣetra.
There are eight million four hundred thousand species of life, and according to our work, we get some body, some type of body. And if we work in the modes of goodness, then we get still better body in higher planetary system, long duration of life, better standard of living condition, more and more, thousand times, thousand times. Whatever comforts and facilities we have got here on this planet, if we work in the modes of goodness, then we get more and more facilities.
Similarly, if we work just like animals, then we are degraded more and more downwards. Tala, Atala, Talātala, Pātāla, like that. There are planetary systems, and similarly, there are higher planetary system. You can see every day. Each and every star means they are different planetary system. So according to your work, you are promoted or degraded or you keep here.
- ūrdhvaṁ gacchanti sattva-sthā
- madhye tiṣṭhanti rājasāḥ
- jaghanya-guṇa-vṛtti-sthā
- adho gacchanti tāmasāḥ
- (BG 14.18)
It is up to you. In another place, Kṛṣṇa says,
- yānti deva-vratā devān
- pitṟn yānti pitṛ-vratāḥ
- bhūtāni yānti bhūtejyā
- yānti mad-yājino 'pi mām
- (BG 9.25)
The same thing. If you desire, you can promote yourself to the higher—that is within the material world—higher planetary system for better comfort of life, better, long duration of life. That you can go. Yānti deva-vratā devān.
