This form of body... We have got by evolutionary process. It is a chance given by the nature to understand what is God. This is the main business of this body. Not that economic development. That is not the business of human body. Sense gratification. Sense gratification is there in the animals. That is stated in the Śrīmad-Bhāgavatam. Nāyaṁ deho deha-bhājāṁ nṛloke kaṣṭān kāmān arhate viḍ-bhujāṁ ye (SB 5.5.1). The human form of life is not meant for to live like the dogs and the hogs. They are busy always for maintaining the body. They are busy. They have no other business. They cannot understand. If I bring some dog in this meeting and try to make him understand, "Please note that you are not this body." It is not possible for them to understand. But a human being, he may be educated like dogs and hog, but if he's given reasonably the, as Kṛṣṇa is giving that the soul is the proprietor of this body and he is as he's changing in this body He's a child-child means he has got a child's body. Baby means he has got a baby's body. Young man means he has a youth's body. So this body has been changed. Similarly when this body is useless, no more can be used, then he transmigrates to another body. Tathā dehāntara-prāptir.
Now what kind of body he's going to get? Because I have already explained. There are 8,400,000 different forms of body. So the answer is he can get any of these forms. There is no guarantee that he will again get the American body or Englishmen body or Swiss body—not like that. That will depend on nature. That is not in your hand. As soon as you change your body, the next change will be offered by nature according to your desire. So in this life we are creating different types of desires. Therefore, we find different types of bodies. This is nature's work. Prakṛteḥ kriyamāṇāni guṇaiḥ karmāṇi sarvaśaḥ (BG 3.27). Don't think that you are independent. None of us are independent. We may think independently that "There is no God, there is no nature's work, we are everything." That crazy statements may be there, but there is good management, beyond our conception. As you see there is good management in the natures—exactly in due course of time the sun is rising, the moon is rising, the seasons are being changed, the water is there in the ocean, it is not transgressing the limit, the Pacific Ocean, the Atlantic Ocean. There is full control of the material nature. And behind this material nature, there is God. Prakṛteḥ kriyamāṇāni (BG 3.27). Prakṛti, nature is working, but nature is working under the direction of God. That we get information from this Vedic literature.
