So I shall further explain one song sung by Narottama dāsa Ṭhākura. Narottama dāsa Ṭhākura was one of our predecessor ācāryas, teacher, and his songs are accepted in our Vaiṣṇava society as Vedic truth. He has written in simple language, but it contains the Vedic truth. So he has got many songs. One of the songs is hari hari biphale janama goṅāinu . He says, "My dear Lord, I am simply wasting the valuable time of my life." Biphale janama goṅāinu. Everyone takes birth as human being, but he does not know how to utilize it. He utilizes it just like animal. The animal eats; we simply make arrangement of eating unnaturally. That is our advancement. In the animal kingdom, every particular animal has got a particular type of food. Just like tiger. A tiger eats flesh and blood, but if you give tiger nice oranges or grapes, he'll not touch it, because that is not his food. Similarly, a hog. A hog eats stool. If you give the hog nice halavā, it will not touch. You see? So every particular animal has got a particular type of food. Similarly, we human beings, we have got our particular type of food also. What is that? Fruits, milk, grains. Just like our teeth is made—you take a fruit, you can easily cut into pieces by this tooth. But if you take a piece of flesh, it will be difficult to cut with these teeth. But a tiger has got particular type of teeth, he can immediately cut into pieces the flesh. So we are advancing in education, but we do not study even of our teeth. We simply go to the dentist. That's all. This is our advancement of civilization. The tiger never goes to dentist. Although its teeth are so strong that immediately he can into pieces, but he doesn't require a dentist, because he doesn't eat anything which is unnatural for him. But we eat anything damn; therefore we require the help of dentist.
So our human being has got a particular type of business. That business is to study or to discuss on the bhāgavata life. That is our natural. Bhāgavata-dharma. We should try to understand Bhagavān. Bhāgavata-dharma, I have already explained. Bhagavān and the bhakta or bhāgavata, their relationship, that is called bhāgavata-dharma. So it is very easy. How? Now simply you have to hear about Kṛṣṇa.
