So what is the king of education? Just like we have got a different status of life in the material world, similarly, in the education also, somebody is M.A., somebody is B.A., somebody is school-leaving certificate, somebody is three years, somebody is four years. There are different grades of education. Now, what is the summum bonum, highest, topmost education? This topmost education is Kṛṣṇa consciousness, topmost education. Rāja-vidyā. Jīvātmā yathātmādi-rahasyānāṁ rājaḥ. Real knowledge is: "So what I am?" This is real knowledge. Unless we come to this point, that "What I am?" that is not knowledge.
Just like Caitanya Mahāprabhu, when He began His preaching, His first disciple was Sanātana Gosvāmī. He was a finance minister of Nawab Hussain Shah, but being attracted with Caitanya Mahāprabhu's movement, he retired from service and he joined Lord Caitanya. So at that time, when he came to Caitanya for the first time, his inquiry was that "What is education? What is education?" He was educated. He was highly educated. In those days Persian language was being taught in England, er, in India. Just like during British rule English language was taught to us, similarly, during Pathan rule, Persian language was state language. Besides that, Sanātana Gosvāmī was a great scholar in Sanskrit also. Still, he inquired that "What is education? What is education?" Why he inquired like that? He placed before the Lord that "People in general, they call me very educated, and I am also so fool that I accept that I am educated." So the next question is: "Then why do you think that you are not educated? You are great scholar in Sanskrit, you are great scholar in Persian language. Why do you think that you are not educated?" He replied that "I am thinking 'not educated' because I do not know what I am. I do not know what I am. I do not wish to be a suffering member, but these material miseries is enforced upon me. I do not know wherefrom I have come, where I have to go, and still people, they think that I am very much educated and they designate me that I am a great scholar, and I am satisfied. But I am such a fool that I do not know what I am."
Actually, this is the position of our present situation. We are very much proud of our advancement of education. But if you inquire from various persons that "What you are?" hardly some will answer what he is. Everyone is under the conception of this body. But we are not actually this body. This question we have discussed various times, many times. So this after passing this examination that "I am not this body," then one who, one comes into the real knowledge. That is real knowledge, "What I am." That is the beginning. So the knowledge about which Lord Kṛṣṇa is now imparting, giving instruction to Arjuna, He says, "This is rāja-vidyā." Rāja-vidyā means to know oneself what he is and act accordingly. That is called rāja-vidyā. If I do not know what I am, what is my position, then if I am in mistaken about my situation, then all activities, what I am doing, they are all mistaken. They are all illusion. Therefore this position, rāja-vidyā, means one should know himself, what he is, and act accordingly. Simply by knowing that "I am not this material body," that is not sufficient. You must act accordingly, that you are not material; you are spiritual. That spiritual activity is called Kṛṣ..., act in Kṛṣṇa consciousness, and that is called rāja-vidyā, the king of all education.
Rāja-vidyā rāja-guhyam. Rāja-guhyam. Rāja-guhyam means confidential, very confidential. It is not possible to accept this Kṛṣṇa consciousness very easily, but by the mercy of Kṛṣṇa and by the mercy of Lord Caitanya, it is very easily delivered to us through this chanting Hare Kṛṣṇa Hare Kṛṣṇa Kṛṣṇa Kṛṣṇa Hare Hare, Hare Rāma Hare Rāma Rāma Rāma Hare Hare. Lord Caitanya has discussed a very analytical study of the living entity. He has analyzed that the living entities... There are innumerable living entities all over the universe. If you dig earth, you'll find many living entities. If you make a study of the air, you'll find many living entities. If you go deep into the water, you'll find living entities. So all over the universe there are full of different types of living entities. And He has divided all these living entities into two classes. Some are moving and some are not moving. Just like trees, plants, grass, they cannot move. Stone. Stone has also life, but it is not developed conscious. It is too much covered, stone life. Similarly, a person, even in human body, if he does not understand his position, he's almost stonelike. So these are stones, trees, grass and so many others. They are "not-moving" living entities. And there are moving entities just like aquatics, beasts, birds, reptiles, human being, demigods, oh, celestial angels, so many. There are moving. So out of the moving entities, very small number are human beings. There are 8,400,000's of species of life. Out of that, only 400,000 species of life are this human body.
So Lord Caitanya says, "Out of these 400,000 species of life, some of them are civilized. And out of many civilized persons, they are actually devoted to the scriptures, not all." Some of them, they agree that "I belong to Christian religion," "I belong to Hindu religion," or "I belong to Muhammadan religion," but at the present age, mostly they simply claim that "I belong to this religion" but do not believe in the scripture, mostly. So those who are believing in the scriptures, they are mostly attracted by pious, philanthropic activities. They, some of them, those who actually believe that charity is very good thing, and... Religious means these three things: yajña-dāna-tapaḥ. Yajña-dāna-tapaḥ. Yajña means sacrifice, dāna means charity, and tapaḥ means penance. Just like brahmacārī. It is tapasya. Tapasya. A sannyāsī, it is tapasya. Tapaḥ. Tapaḥ means penance, voluntarily accepting very rigid principles of life. That is called tapasya. And charity. Charity means voluntarily giving away his material possessions. That is charity. And yajña, sacrifice. Sacrifice, of course, you have no experience. Not you, but we all. Nowadays, in the present days, there is no sacrifice.
But we get information from such historical literature as Mahābhārata. Mahābhārata is called history in the Vedic literature. So kings were performing very big sacrifices. Millions of rupees, millions of valuables, gold and silver, they were distributed. Oh, that is not possible. That was being done by the kings. Kings used to collect tax from the citizens but at the same..., at the time when they performed sacrifice, they were distributed to all the citizens, all of them. So that process is not. Nowadays the state simply collects taxes but never distributes. So we have no idea what is yajña. But this yajña is the performance of kings or the heads of the state, and dāna of the general householders, and tapasya for brahmacārī, sannyāsī, vānaprastha. So these are different kinds of rules in religious life.
So those who believe in scriptures, they adopt, not all. Just like I explained that mostly people, they simply accept a certain faith. Mouth, in mouth only. Actually, they do not do anything. Do not do anything. So out of that many, millions of people like that, somebody are religious, really religious, who perform this sacrifice, charity, and penances. So Lord Caitanya says, "Out of many millions of persons who are actually engaged in charity, and," I mean to say, "penance and sacrifice, some of them become in perfect knowledge what he is." So this knowledge is... Just see how He's making analytical study of the living entities. Beginning from eighty-eight, er, eight hundred, 8,400,000 species of life, He's selecting only few human civilized life; then addicted to the, I mean to say, certain kind of faith; then extracting them who are actually believing; and then those who are actually believing. Out of them, those who are sacrificing, making charities and adopting penances, out of many millions of like, persons like that, some of them are actually in knowledge what he is.
You'll find in your country also. There are many foundations. They are making charities. But hardly you'll find amongst them that he knows that what he is. So out of many millions of these religious persons, some of them know what he is, "I am not this body." Now, simply theoretically knowing that "I am not this body; I am spirit soul," that is not perfect. You have to actually become liberated from the material entanglement. That is called mukti, liberation. So out of many thousands of persons who are in the knowledge what they are or what he is, some of them are actually liberated. Liberated. And out of many thousands of people who are liberated, they can understand what is Kṛṣṇa. So Kṛṣṇa understanding is not very easy job. But Kṛṣṇa is so kind because He knows that in this age, in this age of Kali, it will be very difficult for persons to become liberated under the process—first to become civilized, then to become religious, then to perform this charity, sacrifices, then come to the platform of knowledge, then, after coming to the platform of knowledge, you come to the platform of liberation, and after being liberated, you can know what is Kṛṣṇa.
