It appears that five thousand years ago the society also needed the services of the dramatists, artists, dancers, singers, historians, genealogists, public speakers, etc. Dancers, singers and dramatic artists mostly hailed from the śūdra community, whereas the learned historians, genealogists and public speakers hailed from the brāhmaṇa community. All of them belonged to a particular caste, and they became so trained in their respective families.
(Srimad Bhagavatam-----1:11:20-----purport).

Lord Śrī Kṛṣṇa was invited by Mahārāja Yudhiṣṭhira to look into the supervision of the performances of yajña, and the Lord, to abide by the orders of His elderly cousin, caused the performance of yajñas by learned twice-born brāhmaṇas. Simply taking birth in the family of a brāhmaṇa does not make one qualified to perform yajñas. One must be twice-born by proper training and initiation from the bona fide ācārya. The once-born scions of brāhmaṇa families are equal with the once-born śūdras, and such brahma-bandhus, or unqualified once-born scions, must be rejected for any purpose of religious or Vedic function. Lord Śrī Kṛṣṇa was entrusted to look after this arrangement, and perfect as He is, He caused the yajñas to be performed by the bona fide twice-born brāhmaṇas for successful execution.
(Srimad Bhagavatam-----1:12:35-----purport).

Due to Mahārāja Parīkṣit's good government, even a boy of tender age, who was playing with other inexperienced boys, could become as powerful as a qualified brāhmaṇa. This boy was known as Śṛṅgi, and he achieved goodtraining in brahmacarya by his father so that he could be as powerful as a brāhmaṇa, even at that age. But because the age of Kali was seeking an opportunity to spoil the cultural heritage of the four orders of life, the inexperienced boy gave a chance for the age of Kali to enter into the field of Vedic culture. Hatred of the lower orders of life began from this brāhmaṇa boy, under the influence of Kali, and thus cultural life began to dwindle day after day. The first victim of brahminical injustice was Mahārāja Parīkṣit, and thus the protection given by the King against the onslaught of Kali was slackened.
(Srimad Bhagavatam-----1:8:32-----purport).

Without being qualified, one cannot become a brāhmaṇa or medical practitioner, and that is the verdict of all scriptures and social orders. Herein Śṛṅgi, a qualified son of a great brāhmaṇa, attained the required brahminical power both by birth and by training, but he was lacking in culture because he was an inexperienced boy.
(Srimad Bhagavatam-----1:8:33-----purport).

It is said that one should become a brāhmaṇa before one can understand the Vedic statements, and this stricture is as important as the stricture that no one shall become a lawyer who has not qualified himself as a graduate. Such a stricture is not an impediment in the path of progress for anyone and everyone, but it is necessary for an unqualified understanding of a particular science. Vedic knowledge is misinterpreted by those who are not qualified brāhmaṇas. A qualified brāhmaṇa is one who has undergone strict training under the guidance of a bona fide spiritual master.
(Srimad Bhagavatam-----2:2:27-----purport).

Five thousand years ago, when the social status of human society was in perfect Vedic order, the yoga process mentioned herein was a common affair for everyone because everyone, and especially the brāhmaṇa and kṣatriya, was trained in the transcendental art under the care of the spiritual master far away from home, in the status of brahmacarya. Modern man, however, is incompetent to understand it perfectly.
(Srimad Bhagavatam-----2:2:30-----purport).

The brahmacāri, or a boy from the age of five years, especially from the higher castes, namely from the scholarly parents (the brāhmaṇas), the administrative parents (the kṣatriyas), or the mercantile or productive parents (the vaiśyas), is trained until twenty-five years of age under the care of a bona fide guru or teacher, and under strict observance of discipline he comes to understand the values of life along with taking specific training for a livelihood.
(Srimad Bhagavatam-----2:7:6-----purport).

Similarly, there is the life of Ajāmila (Sixth Canto), who was the son of a brāhmaṇa and was educated and trained properly in the discharge of the duties of abrāhmaṇa, but who in spite of all this, because he contacted the bad association of a prostitute, was put into the path of the lowest quality of caṇḍāla, or the last position for a human being. Therefore the Bhāgavatam always recommends the association of the mahat, or the great soul, for opening the gate of salvation.
(Srimad Bhagavatam-----2:10:41-----purport).

Because the scientific division of four varṇas and four āśramas is now being extinguished, the entire world is being governed by unwanted men who have no trainingin religion, politics or social order, and it is in a very deplorable condition. In the institution of four varṇas and four āśramas there are regular training principles for the different classes of men. Just as, in the modern age, there is a necessity for engineers, medical practitioners and electricians, and they are properly trained in different scientific institutions, similarly, in former times, the higher social orders, namely the intelligent class (the brāhmaṇas), the ruling class (the kṣatriyas) and the mercantile class (the vaiśyas), were properly trained. Bhagavad-gītā describes the duties of the brāhmaṇas, kṣatriyas, vaiśyas and śūdras. When there is no such training, one simply claims that because he is born in a brāhmaṇa or kṣatriya family, he is therefore a brāhmaṇa or a kṣatriya, even though he performs the duties of a śūdra. Such undue claims to being a higher-caste man make the system of scientific social orders into a caste system, completely degrading the original system. Thus society is now in chaos, and there is neither peace nor prosperity. It is clearly stated herein that unless there is the vigilance of a strong king, impious, unqualified men will claim a certain status in society, and that will make the social order perish.
(Srimad Bhagavatam-----3:21:55-----purport).

A person trained to the stage of understanding the Absolute Truth is a brāhmaṇa, and when such a brāhmaṇa is veda jña, he understands the purpose of Veda. The purpose of Veda is to understand the Absolute. One who understands the Absolute Truth in three phases, namely Brahman, Paramātmā and Bhagavān, and who understands the term Bhagavān to mean the Supreme Personality of Godhead, is considered to be the best of the brāhmaṇas, or a Vaiṣṇava.
(Srimad Bhagavatam-----3:29:31-----purport).

The Vedic literatures cannot be understood unless one has developed the brahminical qualifications. It is regrettable, therefore, that persons who have no brahminical qualifications and have never been trained under a bona fide spiritual master nevertheless comment on Vedic literatures like the Śrīmad-Bhāgavatam and other purāṇas, for such persons cannot deliver their real message. Ruci was considered a first-class brāhmaṇa; therefore he is mentioned here as brahma-varcasvī, one who had full prowess in brahminical strength.
(Srimad Bhagavatam-----4:1:3-----purport).

Dhruva Mahārāja is described herein as kṣatra-bandhuḥ, which indicates that he was not fully trained as a kṣatriya because he was only five years old; he was not a mature kṣatriya. A kṣatriya or brāhmaṇa has to take training. A boy born in the family of a brāhmaṇa is not immediately a brāhmaṇa; he has to take up the training and the purificatory process.
(Srimad Bhagavatam-----4:12:43-----purport).

Anyone can join the International Society for Krishna Consciousness and be initiated to become twice-born. As recommended by Sanātana Gosvāmī, by the process of initiation and authorized training, any man can become twice-born. The first birth is made possible by the parents, and the second birth is made possible by the spiritual father and Vedic knowledge. Unless one is twice-born one cannot understand the transcendental characteristics of the Lord and His devotees. Study of the Vedas is therefore forbidden for śūdras. Simply by academic qualifications a śūdra cannot understand the transcendental science. At the present moment, throughout the entire world the educational system is geared to produce śūdras. A big technologist is no more than a big śūdra. Kalau śūdra-sambhavaḥ: in the age of Kali, everyone is a śūdra. Because the whole population of the world consists only of śūdras, there is a decline of spiritual knowledge, and people are unhappy. The Kṛṣṇa consciousness movement has been started especially to create qualified brāhmaṇas to broadcast spiritual knowledge all over the world, for thus people may become very happy.
(Srimad Bhagavatam-----4:12:48-----purport).

The word vṛddhāśrayam is very significant in this verse. Vṛddha refers to one who is advanced in knowledge. There are two kinds of old men—he who is advanced in years and he who is experienced in knowledge. One who is advanced in knowledge is actually vṛddha (jñāna-vṛddha); one does not become vṛddha simply by advancing in age. Vṛddhāśrayam, a person who takes shelter of a superior person who is advanced in knowledge, can acquire all the good qualities of a brāhmaṇa and be trained in good behavior. When one actually attains good qualities, becomes grateful for the mercy of the Supreme Personality of Godhead and takes shelter of a bona fide spiritual master, he is endowed with all opulence. Such a person is a brāhmaṇa or Vaiṣṇava. Therefore Pṛthu Mahārāja invokes the blessings and mercy of the Supreme Personality of Godhead, with His associates, devotees, Vaiṣṇavas,brāhmaṇas and cows.
(Srimad Bhagavatam-----4:21:44-----purport).

It is essential for human society to have a section of men perfectly trained as qualified brāhmaṇas according to the instructions of Vedic knowledge. Those below the brahminical qualification—administrators, merchants and workers—should take instructions from those ideal people who are considered to be intellectuals.
(Srimad Bhagavatam-----5:4:15-----purport).

Although Ṛṣabhadeva knew all the Vedic instructions perfectly well, He nonetheless followed the instructions of the brāhmaṇas in order to perfectly maintain the social order. The brāhmaṇas would give advice according to the śāstras, and all the other castes would follow. The word brahma means "perfect knowledge of all activities," and this knowledge is very confidentially described in the Vedic literatures. Men trained perfectly as brāhmaṇas should know all Vedic literature, and the benefit derived from this literature should be distributed to the general populace. The general populace should follow the perfect brāhmaṇa. In this way, one can learn how to control the mind and senses and thus gradually advance to spiritual perfection.
(Srimad Bhagavatam-----5:4:16-----purport).

To prove the strength of devotional service, Śukadeva Gosvāmī described the history of Ajāmila. Ajāmila was a resident of Kānyakubja (the modern Kanauj). He wastrained by his parents to become a perfect brāhmaṇa by studying the Vedas and following the regulative principles, but because of his past, this youthful brāhmaṇa was somehow attracted by a prostitute, and because of her association he became most fallen and abandoned all regulative principles.
(Srimad Bhagavatam-----6:1:-----summary).

Through the Kṛṣṇa consciousness movement, we are trying to train young people to become devotees and return home, back to Godhead, by following rigid regulative principles, but our service is appreciated neither in India nor abroad in the Western countries where we are endeavoring to spread this Kṛṣṇa consciousness movement. In India the castebrāhmaṇas have become enemies of the Kṛṣṇa consciousness movement because we elevate foreigners, who are supposed to be mlecchas and yavanas, to the position of brāhmaṇas. Wetrain them in austerities and penances and recognize them as brāhmaṇas by awarding them sacred threads. Thus the caste brāhmaṇas of India are very displeased by our activities in the Western world.
(Srimad Bhagavatam-----6:4:39-----purport).

If one is trained to honor and worship the cows and brāhmaṇas, he is actually civilized. The worship of the Supreme Lord is recommended, and the Lord is very fond of the cows and brāhmaṇas (namo brahmaṇya-devāya go-brāhmaṇa-hitāya ca). In other words, a civilization in which there is no respect for the cows and brāhmaṇas is condemned. One cannot become spiritually advanced without acquiring the brahminical qualifications and giving protection to cows. Cow protection insures sufficient food prepared with milk, which is needed for an advanced civilization. One should not pollute civilization by eating the flesh of cows. A civilization must do something progressive, and then it is an Āryan civilization. Instead of killing the cow to eat flesh, civilized men must prepare various milk products that will enhance the condition of society. If one follows the brahminical culture, he will become competent in Kṛṣṇa consciousness.
(Srimad Bhagavatam-----6:18:52-----purport).

The picture of a proper human civilization is indirectly described here. In a perfect human civilization there must be a class of men fully trained as perfect brāhmaṇas. Similarly, there must be kṣatriyas to rule the country very nicely according to the injunctions of the śāstras, and there must be vaiśyas who can protect the cows. The word gāvaḥ indicates that cows should be given protection. Because the Vedic civilization is lost, cows are not protected, but instead indiscriminately killed in slaughterhouses. Such are the acts of demons. Therefore this is a demoniac civilization. The varṇāśrama-dharma mentioned here is essential for human civilization. Unless there is a brāhmaṇa to guide, a kṣatriya to rule perfectly, and a perfect vaiśya to produce food and protect the cows, how will people live peacefully? It is impossible.
(Srimad Bhagavatam-----7:2:12-----purport).

The members of our Kṛṣṇa consciousness movement are in a position similar to that of Prahlāda Mahārāja. All over the world, ninety-nine percent of the people are godless demons, and therefore our preaching of Kṛṣṇa consciousness, following in the footsteps of Prahlāda Mahārāja, is always hampered by many impediments. Because of their fault of being devotees, the American boys who have sacrificed everything for preaching Kṛṣṇa consciousness are charged with being members of the CIA. Moreover, the seminal brāhmaṇas in India, who say that one can become a brāhmaṇa only if born in a brāhmaṇa family, charge us with ruining the Hindu system of religion. Of course, the fact is that one becomes a brāhmaṇa by qualification. Because we are training Europeans and Americans to become qualified and are awarding them brahminical status, we are being charged with destroying the Hindu religion. Nonetheless, confronting all kinds of difficulties, we must spread the Kṛṣṇa consciousness movement with great determination, like that of Prahlāda Mahārāja. In spite of being the son of the demon Hiraṇyakaśipu, Prahlāda never feared the chastisements of the seminal brāhmaṇa sons of a demoniac father.
(Srimad Bhagavatam-----7:2:16-----purport).

Formerly, of course, the members of the higher castes—the brāhmaṇas, kṣatriyas and vaiśyas (everyone but the śūdras)—were trained in the guru-kula to adhere to a life of renunciation and sense control by practicing brahmacarya and mystic yoga. Then they were allowed to enter household life. There have consequently been many instances in which great kings and emperors have given up household life. Although they were extremely opulent and were the masters of kingdoms, they could give up all their possessions because they were trained early as brahmacārīs.
(Srimad Bhagavatam-----7:6:10-----purport).
