Udaya means awaken. The Kṛṣṇa consciousness is there in everyone's heart. It is dormant. Simply by śravaṇādi, by pure hearing process . . . just like a man is sleeping. The consciousness is there, but he appears to be unconscious. He is sleeping. But if somebody calls him, "Mr. Such-and-such, wake up, wake up, wake up." So after two, three callings, he wakes up. He remembers, "Oh, I have got to do so many things." Similarly, the Kṛṣṇa consciousness is dormant in everyone's heart. This Hare Kṛṣṇa mantra is the process of awakening. That's all. This Hare Kṛṣṇa mantra, if we chant repeatedly Hare Kṛṣṇa—Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare—then the sleeping man awakens to Kṛṣṇa consciousness. This is the process.
So I do not wish to take much of your time. I have simply given introduction to this movement, Kṛṣṇa consciousness movement. It is very simple thing. You do not lose anything. Suppose you chant Hare Kṛṣṇa at your home. Do you think you will be loser? No. Neither we want any money from you that, "Pay me so many dollars, I give you some particular mantra." No. It is not like that. It is open. Everyone can chant. But if you chant, then you will be benefited. Ceto-darpaṇa-mārjanam (CC Antya 20.12). Your heart will be cleansed.
Now we are in so many consciousness, "I am this, I am that, I am this, I am that, I am this, I am that." And therefore there is so much trouble all over the world, because we have misidentified with this body, which is simply shirt and coat. Suppose we are sitting, so many ladies and gentlemen, if we simply fight on the basis of our dress, "Oh, you are not in such dress. I am in such dress. Therefore you are my enemy," this is not very good argument. Because I am in different dress, so I am not your enemy. And because you are in different dress, you are not enemy. But that is going on. That is going on. "I am American," "I am Indian," "I am Chinese," "I am Russian," "I am this," "I am that." And the fighting is going on on this point only.
So if you take to Kṛṣṇa consciousness, this rascaldom will go. Just like these you see, all the students. They don't think that they are Indian or American or African or . . . no. They are thinking, "We are servant of Kṛṣṇa." That is wanted. That is wanted. Unless we are coming to that point of understanding, ceto-darpaṇa-mārjanam . . . (CC Antya 20.12). Ahaṁ brahmāsmi: "I am pure soul, spirit soul. This body is, the material body, is my covering."
That is called jñāna, knowledge. And as soon you come to the point of knowledge, then there will be vairāgya. Vairāgya means renunciation. Just like these boys, these girls. They are American. They lived under their parents in high standard of life. Now they can sit anywhere. They can sit on the street, because they have forgotten this bodily concept of life. They are simply thinking in terms of Kṛṣṇa consciousness, "I am servant of Kṛṣṇa."
