We have to purify our existence. This is the mission of human life. At the present moment we are transmigrating from one body to another, and there are 8,400,000 species of life we are going through according to karma. Karmaṇā daiva-netreṇa jantur deha upapattaye (SB 3.31.1). How we develop a certain type of body, that is stated—everything is stated in the Śrīmad-Bhāgavatam—by our karma. I have explained last night, it is just like infection. We are associating with different types of the modes of material nature. Generally there are three types of material nature, three qualities: sattva-guṇa, rajo-guṇa, tamo-guṇa. Now, you multiply these three by three: it becomes nine. And again you multiply nine by nine: it becomes eighty-one. It is mixture. Here these guṇas, the qualities, are not pure. They are mixed up. Just like color mixing. Originally there are three colors: red, yellow and blue. And you mix it. . . Those who are color expert, they can display many thousands of colors. So similarly, in the nature's way there are different colors or different guṇas, and every one of us, we have got a particular type of guṇa with different desires, different plans, different so many things.
Now, in the human form of life, you have got the chance to discriminate yourself or separate yourself from these colorful different species of life. That is the main duty of human form of life. Labdhvā sudurlabham idaṁ bahu-sambhavānte (SB 11.9.29). We do not know; we have forgotten that how many species of life we have come through, transmigrating from one after another. Therefore this human form of life is called labdhvā sudurlabham idaṁ bahu-sambhavānte. After many, many births. We should not misuse it. Very responsible life. If you are misled, that is a dangerous civilization. That is going on.
