So in pursuance of the order of Lord Caitanya Mahāprabhu, following His footsteps, we are trying to introduce this saṅkīrtana movement, Hare Kṛṣṇa, and it is coming out very successful. Everywhere. I am especially preaching in the foreign countries. All over Europe, America, Japan, Canada, Australia, I am traveling. Malaysia. And anywhere I have introduced this saṅkīrtana movement—we have got different centers, about sixty centers—they have been received with great pleasure. Just like you saw these boys and girls. I have not imported them from India, but they have taken this movement very seriously, and they will take it, because it appeals to the soul directly. We have got different status of our life. Bodily concept of life, mental concept of life, intellectual concept of life and spiritual concept of life. So actually we are concerned with the spiritual concept of life, athāto brahma jijñāsā. If you are allured by the bodily concept of life, then we are no better than these dogs and..., cats and dogs. Yasyātma-buddhiḥ kuṇape tri-dhātuke (SB 10.84.13). If we accept that "I am this body," then we are no better than the cats and dogs, because their concept of life is like that.
When we understand that "I am not this body...," As Kṛṣṇa wanted to impress upon Arjuna in the beginning of His teaching of Bhagavad-gītā: "First of all try to understand what you are. Why you are lamenting in the bodily concept of life? You have to fight. Certainly you have to fight with your brothers and brother-in-laws and nephews, other side. And you are lamenting. But first of all understand whether you are body or not." That is the beginning of Bhagavad-gītā. He tried to make him understood that you are not body. So these instructions were not for Arjuna. For everyone. We have to first of all learn that "I am not this body. I am spirit soul." Ahaṁ brahmāsmi. That is Vedic instruction. And as soon as you come to this point, if you are firmly convinced that you are not this body, that is called brahma-bhūta (SB 4.30.20) stage, Brahman realization stage. That is knowledge, real knowledge. Knowledge, advancement of knowledge for eating, sleeping, mating, that is animal knowledge. The animals also, the dog also knows how to eat, how to sleep, how to mate and how to defend. So if our education is only on these points... The dog is eating according to his nature, but we are also eating in a nice plate, nicely cooked food in a nice table, but the principle is eating. That is not advancement, that "I am eating in a better plate in a better place than the dog; therefore I am advanced." But you are eating, that's all. Similarly sleeping. You may sleep in a very nice apartment, six story building or 102nd story building; a dog is lying on the street. But when he sleeps and when you sleep, there is no difference. You cannot know whether you are sleeping in a skyscraper building or on the ground, because you are dreaming something else which has taken you from your bed. You have forgotten that "My body is lying there on the bed, and now I am flying in the air," dreaming. So this sleeping method, if you improve, that is not advancement of civilization. Similarly mating. The dog has no social custom. Whenever there is another she-dog, he mates on the street, and you may do very silent in a secret place, but the mating is there. But people are learning how to mate like dog. So in this way defending. A dog has also his defending measures. He has got teeth and nails. He can defend himself. And you might have atom bombs. But the measure is defending. That's all.
Therefore śāstra says that human life is not meant only for these four principles of life, bodily demands. There is another thing. That another thing is brahma-jijñāsā. Athāto brahma jijñāsā. A human being should be inquisitive to learn what is Absolute Truth. So that education is lacking. Therefore without this brahma-jijñāsā education, brahma jānātīti brāhmaṇaḥ. According to Vedic civilization, a brāhmaṇa is learned. Paṇḍita. A brāhmaṇa is called paṇḍita because brāhmaṇa means one who knows Brahman. Brahma jānātīti brāhmaṇaḥ. Therefore he is called paṇḍita. In India the brāhmaṇa is addressed as paṇḍita. Paṇḍita means a brāhmaṇa is expected to know Brahman; therefore he is brāhmaṇa. Not by birth. Brahma jānāti. Janmanā jāyate śūdraḥ. By birth everyone is śūdra, fourth-class man. Janmanā jāyate śūdraḥ saṁskārād bhaved dvijaḥ. And when he's reformed by the purificatory process...
There are daśa-vidha-saṁskāra, ten kinds of purificatory process. When one undergoes all these processes and at last comes to the spiritual master who gives him sacred thread as recognition of his second birth... Dvija. Dvija means second birth. One birth by the father and mother, and the other birth is by the spiritual master and Vedic knowledge. That is called second birth. Saṁskārād bhaved dvijaḥ. At that time he is given chance to study and understand what is Vedas. Veda-pāṭhād bhaved vipraḥ. By studying very nicely all the Vedas, one becomes vipra. Then, when he actually realizes what is Brahman and his relationship with Him, then he becomes a brāhmaṇa. And above that situation, when from Brahman understanding, impersonal Brahman understanding, he comes to the platform of understanding Viṣṇu, Lord Viṣṇu, the Supreme Personality of Godhead, he becomes a Vaiṣṇava. This is the process. That is the perfectional process. Kṛṣṇa therefore says in the Bhagavad-gītā, janma karma me divyaṁ yo jānāti tattvataḥ. "Anyone who knows Me in truth," what happens to him? Tyaktvā dehaṁ punar janma naiti: (BG 4.9) "Such persons, after giving up this body, do not come back again in this material world to accept a material body." Then what happens to him? Mām eti: "He comes to Me, back to home, back to Godhead."
