From the very beginning of life . . . just like Prahlāda Mahārāja advised, kaumāra ācaret prājño dharmān bhāgavatān iha (SB 7.6.1). The boys . . . he was five-years-old boy. He said: "My dear . . ." He was preaching amongst his class friend. This is Vaiṣṇavism. Even a five . . . just like our Sarasvatī, Śyāmasundara's daughter. She also preaches. She goes sometimes, "Do you know what is Kṛṣṇa?" If somebody says: "No, I do not know"—"The Supreme Personality of Godhead." You see? This is natural. Simply one has to be given the chance.
Because this, I mean to say, small girl has got the chance to live amongst Kṛṣṇa conscious people from the very birth, she's developing that, "Oh, I shall also preach. I shall also preach." Developing. Similarly, advancement of Kṛṣṇa consciousness means you will be, I mean to say, pushed how to preach, how to preach. That is one of the signs. Śravaṇaṁ kīrtanam. If you have heard nicely about the Kṛṣṇa consciousness movement, then you must . . . next stage is kīrtanam. Kīrtanam means preaching, chanting. Kīrtanam. Śravaṇaṁ kīrtanaṁ viṣṇoḥ (SB 7.5.23).
So that is our main business from the very beginning of life. Kaumāra ācaret prājño dharmān bhāgavatān iha (SB 7.6.1). This human form of life is so rare, after many, many millions of birth, many, many millions of years rotating through different species of life, by the evolutionary process, we have come to this human form of life. In this life also, if you are simply engaged in the matter of eating sleeping, sense gratification and defending, then where is the advancement? No advancement.
So that inquiry should be there that, "What I am? What I am put into these tribulations of conditional life under the laws of nature?" Unless this question arises in one's mind, he's not a human being, he's animal. Just (like) Sanātana Gosvāmī went to Caitanya Mahāprabhu, and although he was minister, very learned scholar, he said: "My dear Lord, people eulogize me as very big man, learned man, minister. But I know that I do not know what I am. This is my position." Grāmya-vyavahāre kaha ei paṇḍita, tāi satya māni (CC Madhya 20.100): "The people, the ordinary people, common people, they say that 'You are so great scholar, so rich man, minister.' They say like that. But I know that I am fool number one. I do not know what I am." This is the position.
