What is the difference between animal and man? The animal cannot be instructed anything about God. It is not possible for them to understand. But a man, however degraded he may be, if he is trained up, he can understand about God. Just like five years ago, you did not know about Kṛṣṇa. But because you are being trained up, because you are human being, therefore you are taking to Kṛṣṇa consciousness. Which was unknown to you five years ago, now you are taking it to very seriously. Why? Because you are being trained up.
Similarly, God consciousness is there, dormant in every living entity. But the perception varies according to the development of body. Just like child. You say something serious, say, about sex life, they do not understand. But the same child will understand sex life when the consciousness is developed. Similarly, in this material world, our consciousness is covered, God consciousness. So there are different species of life. Just like the aquatics in the ocean; there are so many living entities. But if you preach there Kṛṣṇa consciousness, it is not possible. Their number is far greater than human being. Still, they have no capacity.
Next development, plants and trees, there also, no sensation. You cut the trees, no protest, because there is no sensation. There is practically consciousness . . . there is consciousness, very slight. Sir Jagadish Chandra Bose has proved that when you cut tree, he feels, and that is recorded in, what is called, that machine? (indistinct reply) So everyone has got consciousness. Living entity means there is consciousness. But they have their consciousness only for eating, sleeping, sex life and defending. There is consciousness amongst the fish. Their consciousness is so strong, two miles away if some big fish is coming, they can understand. Immediately they can take precaution, defending. These are all described.
So different animals in different species of life, they have got one type of consciousness very strong. Just like you can see the vultures—it is a low-graded animal—but it goes four miles above the earth and it can see where is a dead body. You cannot do that. You cannot see even twenty yards after. But the animal, another animal, the vulture, he can see . . . from four miles away he can find out where there is a dead body. So this consciousness of eating, sleeping, mating and defending, that is common. In one animal, or . . . it is very strong. In another man, animal, it is not so strong. But this consciousness is there. But this God consciousness is not there except in human being.
So the human society is becoming so degraded that they are trying to forget God. That is their advancement of civilization. The more you deny existence of God and become a so-called rascal scientist, then you are advanced. This is the position. So this position will degrade so much after, say, 400,000's of years, gradually degrading, that at time, Kṛṣṇa will come in His incarnation as Kalki. At that time the Kalki's business will be simply to kill. That's all. No more. No more preaching of Kṛṣṇa consciousness. Simply kill them. That is Kalki avatāra.
That Kalki avatāra is given the father's name. This is called śāstra. This is called scripture. Four hundred thousand's after, 400,000's of years after, Kalki will come. Now, His father's name is given there. Just like Lord Buddha's mother's name is there. So you cannot imitate that, "I am Kalki avatāra." You have to give evidence, what is your father's name. Just see. This is called śāstra. Any rascal comes, "Oh, I am Kṛṣṇa. I am this avatāra and that avatāra," but where is the evidence from the śāstra?
We cannot accept. Just like any gentleman comes, we want to see the credential. Just like in politics, when some ambassador comes to a new country, then he has to officially present his credential so that he will be accepted that, "This gentleman is representative of such-and-such country." That is nice. Unless you give credentials, identity, how I can accept you?
So . . . but people have become rascal. Anyone comes, he says that, "I am incarnation of God," because the people are rascals, they accept another rascal. But if you follow the śāstras and scriptures, then there you will find all the avatāras, their credentials are there—what is the father's name, what is the name of the place he takes birth or appears, what is his business. So . . . what is the time. Everything is given there. So why should you be misled?
So we accept incarnation of God when all the descriptions are corroborated in terms of the authorized śāstra. Otherwise we reject. That is our business. So in this verse . . . why we accept Vedic scripture as solid truth? Because there is no mistake. Otherwise, how it is predicting that yuga-sandhyāyām, "In the last conjunction of the yugas, there will appear the Lord"? Kalkir nāmnā. Nāmnā kalkiḥ. "His name will be Kalki. But He is not ordinary person." Nāmnā kalkir jagat-patiḥ. "He is the Supreme Personality of Godhead. He is not ordinary man. And His father's name is . . ." janitā viṣṇu-yaśaso: "His father's name will be Viṣṇu Yaśi."
The Yaśi title are there in India still. One Mr. Yaśi (pronounced Joshi) corresponds with us. So the Josha, or Joshi, this title is already there. So they are Brāhmins. Here, all the descriptions are not there, but in other place, all the descriptions are there. Not only His father's name, His village, or the place, Sambhal. There is still a place Sambhalpur in India. So everything is there. We should not be misled that "Here is another avatāra, here is another avatāra, here is . . . so many avatāras." No.
So this is called śāstra: what will happen after 400,000's of years, that is mentioned. Future. Just like Lord Buddha's name was there. Bhaviṣyati yuga-sandhyāyām. Bhaviṣyati. Bhaviṣyati means, "He will come." He was not visible. This is śāstra. Śāstra means tri-kāla-jña. The writer of śāstra should be a full cognizant of past, present and future. That is called unmistakable. Past, present and future. Kṛṣṇa says in the Bhagavad-gītā that, "I know past, present and future."
So that is God, or God's scripture: past, present and future. This Bhāgavata was written by God Himself, Vyāsadeva. Vyāsadeva is incarnation of Kṛṣṇa. That we have described, eleventh or some avatāra. So the Kalki will appear. The śāstra is giving indication that after such-and-such year. And another point is this dasyu-prāyeṣu rājasu. The . . . more and more the government will be just like thieves and rogues.
