So there is necessity of a class of men who will act as the brain of the society. That is called brāhmaṇa. That is real human society, where there are four classes of men: one acting as brain; one acting as arms or armies or protection; one acting as belly, or the food digesting machine. . . Unless you eat and digest food, how your body will be maintained? So everything is very scientifically designed in the Vedic civilization. So in the Kali-yuga there is scarcity of brāhmaṇa. Brāhmaṇa is vairāgya. A brāhmaṇa is not interested with pounds, shilling, pence, "Get money and enjoy." That is not brāhmaṇa's business. What is enjoyment? That is illusion. You cannot enjoy, because you are conditioned by the stringent laws of nature, and where is enjoyment? There is no enjoyment. But they are thinking, "I am enjoying." This is called illusion, māyā. There cannot be any enjoyment. When you are not free, when you are conditioned under the stringent laws of. . . You do not like to die; you are forced to die. You must die. You cannot say, "No, I will not die." No, that is not possible. So where is your freedom? But we are declaring, "Now we are independent." This is all illusion.
So Caitanya Mahāprabhu appeared to save us from all these illusions. That is Caitanya Mahāprabhu. Caitanya means living, not dead. If we have no spiritual consciousness, if we have not Kṛṣṇa's consciousness, then we are dead. This. . ., what is this body? This body is dead. Alive or dead, so-called dead, it is already dead because it is matter. But because there is spirit soul, it is moving. The same example: the motorcar, what is this? A lump of matter, some iron, some other metals or some rubbers, some combination. And so long the driver is there—it is moving—it is important so long it is moving. And as soon as the movement stops, you throw it away. That is very good experience in your country. So many useless motorcars are heaped together.
So similarly, the brāhmaṇa means one must know that who is the driver of this body, brahma-jñāna. So at the present moment nobody knows who is driving this body. So therefore all śūdras, fourth-class men. There is no first-class man. But in the human society there must be four classes of men: first class, second class, third class. . . Fourth class also required for assisting the higher, third class. Everything is very nicely described in the Bhagavad-gītā, and Bhagavad-gītā was taught by Kṛṣṇa Himself. But people could not follow Him, misunderstood Him. Therefore Kṛṣṇa again came as Kṛṣṇa Caitanya to teach personally the philosophy of Kṛṣṇa.
Caitanya Mahāprabhu did not teach anything else than what was taught by Kṛṣṇa. Therefore, Sarvabhauma Bhaṭṭācārya said, vairāgya-vidyā-nija-bhakti-yogam śikṣārtham, purāṇah puruṣaḥ. That Supreme Personality of Godhead. . . Vairāgya-vidyā-nija-bhakti-yogaṁ śikṣārtham ekaḥ purāṇaḥ puruṣaḥ śrī-kṛṣṇa-caitanya-śarīra-dhārī (CC Madhya 6.254): "Now You have assumed the form of Śrī Kṛṣṇa Caitanya, but You are Kṛṣṇa." That is also Rūpa Gosvāmī said. We have to follow the mahājanas, great personality, authorities. Mahājano yena gataḥ sa panthāḥ (CC Madhya 17.186). We cannot manufacture a way of life. We have to follow the footprints of mahājana, great personalities. That is the way. Here, at the present moment, everyone is speculating. What is the use of speculation? You are imperfect. Your senses are imperfect. Whatever you establish, because you have established by imperfect senses, they are all imperfect. Therefore they are suffering. There is no solution. So speculative method will not help us.
So Caitanya Mahāprabhu's teaching is. . . It is not as He had manufactured something. He is also following. He quoted one verse from the prayers of Lord Brahmā:
- jñāne prayāsam udapāsya namanta eva
- san-mukharitāṁ bhavadīya-vārtām
- sthāne sthitāḥ śruti-gatāṁ tanu-vāṅ-manobhir
- ye prāyaśo 'jita jito 'py asi tais tri-lokyām
- (SB 10.14.3)
This is a quotation from Śrīmad-Bhāgavatam in Brahma's prayer to Kṛṣṇa. The purport is that you should give up this bad habit of speculation, jñāne prayāsam. Prayāsam means endeavor: "I shall get this knowledge by speculating." This is called jñāna-prayāsam, endeavoring uselessly for knowledge. So udapāsya: you give it up. Jñāne prayāsam udapāsya namanta. Just become submissive. Don't think yourself that you are very learned. Because if the senses are imperfect, how you can be learned? Whatever you see, that is imperfect. Just like we see every day the sun, these eyes. And what we see? It is just like a disc. Is it a disc? It is fourteen hundred times bigger than this earth. So what is the value of your seeing? You cannot see what is behind the wall. Still, you are proud of seeing—"Can you show me? Can you show me God?" And what power you have got to see? That he does not consider. He thinks, "I have got seeing power." Similarly, you study every sense—they are all imperfect, blunt. So any knowledge you acquire by gymnastic of the senses—useless. This is Caitanya Mahāprabhu's teaching. Not Caitanya Mahāprabhu's; it is the Bhāgavata's teaching, and Caitanya Mahāprabhu's the same. So we have to give up this nonsense idea, that "I can attain to the perfect knowledge by speculation, manodharma, by speculation, manodharma, mental gymnastic." This will not help us.
