The person who is taking very much pleasure, dancing in the sea like fish, so he is contaminating that modes of nature so that in next life he will become a fish. He'll be very free to dance with the ocean. (laughter)
Now it will take again millions of years to come to the stage of human being. Jalajā nava-lakṣāṇi sthāvarā lakṣa-viṁśati (Viṣṇu Purāṇa). He has to pass through the fish life. There are 900,000 different species of life. Then you again come to the land—you become trees, plants and so on. Two millions different forms you have to go through. That is evolution. Darwin's theory of evolution, that is not perfectly explained. It is explained in the Vedic literature. So just a tree is standing for ten thousands of years, we had to pass through this life. But there is no perfect knowledge. We are thinking that we are now very nice American body or Indian body. No. It took so many years to come to this life. Therefore śāstra says, labdhvā sudurlābhaṁ idaṁ bahu-sambhavānte (SB 11.9.29): "You have got this human form of life after many, many millions of years' waiting." So do not misuse it. That is Vedic civilization, not to misuse the human form of life.
Nature's law is very, very strict. This life it is given, a chance. Nature gives a chance. Now you get this human form of life, advanced consciousness. Now you make further improvement. That is wanted. From here we can make further improvement. What is that further improvement? We can go to the better planets. There are many better planets. You can go there, heavenly planets. There you can live for ten thousands of years. Ten thousands of years, and that is also not our year. The higher planetary system, their one day—our six months. In that way you can live there for ten thousands of years. And the standard of living condition is thousand times better. Therefore it is called heavenly.
