So you cannot search out by your material... That. Therefore all these universities, they are setting aside, very difficult subject. They are very much proud by creating a horseless carriage. That's all. Formerly horses were drawing carriages. Now there is motorcar. So they are very much proud: "We have invented horseless carriage." Or wingless bird. There is wing, imitation wing of the aeroplane. But you invent that a soul-less body. Then there is credit. That cannot be... No machine can work without a soul. I was talking of this computer. What is called? Computer? Eh? Computer. But still, a trained man requires to handle the computer. Then what is the meaning of this computer? Whatever machine you make... Similarly, we should understand that this great machine, which is known as cosmic manifestation, material nature—there is a supreme spirit which is manipulating. That is Kṛṣṇa. And Kṛṣṇa says. It is confirmed. So our process of knowledge is very easy and perfect. The scientists, they are searching out what is the ultimate cause or ultimate control of this material nature, and they are putting, theorizing different propositions. But our means of knowledge, very easy and perfect because we are hearing from the perfect person, Kṛṣṇa. And He says, mayādhyakṣeṇa (BG 9.10). So immediately we know that all this cosmic machine, which is working so nicely and wonderfully, behind this machine the driver is Kṛṣṇa. Exactly behind a machine here, there is a machine driver, similarly, behind this big machine of material nature, there is Kṛṣṇa.
So our process of knowledge very easy. Kṛṣṇa's book, Bhagavad-gītā, is the knowledge, book of knowledge which is given by the perfect person, Kṛṣṇa. You may argue that "You have accepted Him as a perfect person, but we do not." You may not. But He is perfect person on the evidence of many authorities. It is not by my whims I accept Kṛṣṇa as the perfect person. No. There are many authorities, Vedic authorities. Formerly... Just like Vyāsadeva. He's the author of all Vedic literature, the treasure-house of knowledge, Vedas. He accepts Kṛṣṇa as the Supreme Personality of Godhead. His spiritual master, Nārada, he accepts Kṛṣṇa as the Supreme Personality of Godhead. His spiritual master, Brahmā, he accepts Kṛṣṇa as the Supreme Person. Īśvaraḥ paramaḥ kṛṣṇaḥ (Bs. 5.1), Brahmā says. "The supreme controller is Kṛṣṇa." Īśvara. Īśvara means controller. We are controller, everyone. Nobody can say that "I am without controller." No, that is not possible. Everyone has got a controller. However big officer you may be, you have a controller over your head. But Kṛṣṇa has no controller; therefore He is God. He is controller of everyone, but He has no controller; therefore He's God. So there are many so-called Gods nowadays. Very... God has become very cheap, especially they are imported from India. They are not manufactured in here. You are fortunate. But India, they're coming out, "God," practically every day. They are... The other day, Karandhara was telling me that some God was coming to Los Angeles, and they were requested to receive him. So Kṛṣṇa is not that kind of God. I mentioned in my introduction to Kṛṣṇa book that Kṛṣṇa is not that type of God, manufactured in mystic factory. No. He is God. He was not made God, but He is God.
So the point is that behind this material, big material nature, cosmic manifestation, there is God. That is Kṛṣṇa, and accepted by all authorities. We have to accept things which is accepted by authorities. That is our education. We go to teacher. We go to school. We learn from father, mother. They're all authorities. And our nature is to learn... "Father, what is this?" in childhood. Father says, "This is this, pen. This is spectacle. This is table." So he learns from father, mother, "This is table. This is spectacle. This is pen. This is this. She is my sister. She (He) is my brother." So similarly, if we get information from the authority, and if the authority is not a cheater, then our knowledge is perfect, and very easy. Just like father, mother, never cheats. When the son inquires from the parent, the parent gives exact information, right information. Similarly, if we get right information from the right person, that is perfect knowledge. If you want to reach to the conclusion by speculation, that is imperfect, inductive process. That will never become perfect. It will remain imperfect for all the time. So we get information from the perfect person, Kṛṣṇa. Therefore whatever we speak, that is perfect because we don't speak anything which is not spoken by Kṛṣṇa or authorities who have accepted Kṛṣṇa. That is called disciplic succession. So our process is, process of acquiring knowledge, is very easy and perfect. That is Kṛṣṇa consciousness. We cannot say anything which is not accepted by the authorities coming from Kṛṣṇa. And in the Bhagavad-gītā Kṛṣṇa recommends this process of knowledge: evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). "This knowledge, formerly, all the great saintly kings..." Formerly, there was monarchy. Just like nowadays also, the government is authority. Your President is authority. So in the days of monarchical king, government, the monarch or the king is head of the government. He is authority. But formerly, those authorities, those kings, were ṛṣis, great learned scholars, ṛṣis, great devotees. They were not ordinary men. That system of government was very nice. One person, well talented, well trained as the head of the government, very peacefully he could execute the governmental function. There were many instances, the Vedic civilization, how the kings were perfect. You'll find from Dhruva Mahārāja's instances that Dhruva Mahārāja went to the forest to search out God, and he found out. By severe type of penances and austerities, he found out God within six months. How? He was a five-years-old body, child. According to the direction of his spiritual master, Nārada, he went alone in the forest, although a king's son, very delicate body. So in the first month he simply used to eat some vegetables after three days, each three days. One, two, three—then he eats something, some fruits, some vegetables. Then next three months, each six days, he used to little, drink little water. And next month, in each twelve days, he used to inhale some air. In this way, for six months he stood in one leg and executed these austerities, and at the end of six months, God became manifest before him eye to eye. So if we follow austerities, then it will be possible to see God eye to eye and perfection of life.
