The Supreme Person is described herein as brahmaṇya-deva. Brahmaṇya refers to the brāhmaṇas, the Vaiṣṇavas or the brahminical culture, and deva means "worshipable Lord." Therefore unless one is on the transcendental platform of being a Vaiṣṇava or on the highest platform of material goodness (as a brāhmaṇa), he cannot appreciate the Supreme Personality of Godhead. In the lower stages of ignorance and passion, it is difficult to appreciate or understand the Supreme Lord. Therefore the Lord is described herein as the worshipable Deity for persons in brahminical and Vaiṣṇava culture.
namo brahmaṇya-devāya
go-brāhmaṇa-hitāya ca
jagad-dhitāya kṛṣṇāya
govindāya namo namaḥ
(Viṣṇu Purāṇa 1.19.65)
Lord Kṛṣṇa, the Supreme Personality of Godhead, is the prime protector of brahminical culture and the cow. Without knowing and respecting these, one cannot realize the science of God, and without this knowledge, any welfare activities or humanitarian propaganda cannot be successful.
(Srimad Bhagavatam-----4:21:38-----purport).

The word maṅgala ("auspicious") in this verse is very significant. Śrīla Śrīdhara Svāmī quotes that to do what is good and to reject what is not good is called maṅgala, or auspicious. To do what is good means to accept everything favorable to the discharge of devotional service, and to reject what is not good means to reject everything not favorable for discharging devotional service. In our Kṛṣṇa consciousness movement, we accept this principle by rejecting four prohibited items—namely illicit sex life, intoxication, gambling and flesh—eating—and accepting the daily chanting of at least sixteen rounds of the Hare Kṛṣṇa mahā-mantra and daily meditation three times a day by chanting the Gāyatrī mantra. In this way one can keep his brahminical culture and spiritual strength intact. By following these principles of devotional service strictly, chanting twenty-four hours a day the mahā-mantra—Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare—one makes positive progress in spiritual life and ultimately becomes completely fit to see the Supreme Personality of Godhead face to face.
(Srimad Bhagavatam-----4:21:42-----purport).

Because the ultimate goal of studying or understanding the Vedic knowledge is to find Kṛṣṇa, one who follows the Vedic principles as described above can from the very beginning see all the features of Lord Kṛṣṇa, the Absolute Truth, very distinctly, as one can see one's own face completely reflected in a clear mirror. The conclusion is, therefore, that a brāhmaṇa does not become a brāhmaṇa simply because he is a living entity or is born in a brāhmaṇa family; he must possess all the qualities mentioned in the śāstras and practice the brahminical principles in his life. Thus he ultimately becomes a fully Kṛṣṇa conscious person and can understand what Kṛṣṇa is. How a devotee continuously sees Kṛṣṇa face to face within his heart is described in the Brahma-saṁhitā (5.38) as follows:
premāñjana-cchurita-bhakti-vilocanena
santaḥ sadaiva hṛdayeṣu vilokayanti
yaṁ śyāmasundaram acintya-guṇa-svarūpaṁ
govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
The devotee, by development of pure love for Kṛṣṇa, constantly sees the Supreme Personality of Godhead, who is known as Śyāmasundara, within his heart. That is the perfectional stage of brahminical culture.
(Srimad Bhagavatam-----4:21:42-----purport).

The Supreme Personality of Godhead is worshiped with the prayer namo brahmaṇya-devāya go-brāhmaṇa-hitāya ca. Thus it is clear that the Supreme Personality of Godhead respects and protects the brāhmaṇas and brahminical culture, as well as the cows; in other words, wherever there are brāhmaṇas and brahminical culture, there are cows and cow protection. In a society or civilization in which there are no brāhmaṇas or brahminical culture, cows are treated as ordinary animals and slaughtered, at the sacrifice of human civilization. The specific mention of the word gavām by Pṛthu Mahārāja is significant because the Lord is always associated with cows and His devotees. In pictures Lord Kṛṣṇa is always seen with cows and His associates such as the cowherd boys and the gopīs. Kṛṣṇa, the Supreme Personality of Godhead, cannot be alone. Therefore Pṛthu Mahārāja said, sānucaraś ca, indicating that the Supreme Personality of Godhead is always associated with His followers and devotees.
(Srimad Bhagavatam-----4:21:44-----purport).

According to the Vedic system, after the sacrificial ceremony the brāhmaṇas are invited to eat the remnants of the offered food. When the brāhmaṇas eat the food, it is to be considered directly eaten by the Supreme Lord. Thus no one can be compared to qualified brāhmaṇas. The perfection of evolution is to be situated on the brahminical platform. Any civilization not based on brahminical culture or guided by brāhmaṇas is certainly a condemned civilization. Presently human civilization is based on sense gratification, and consequently more and more people are becoming addicted to different types of things. No one respects brahminical culture. Demoniac civilization is attached to ugra-karma, horrible activities, and big industries are created to satisfy unfathomable lusty desires. Consequently the people are greatly harassed by governmental taxation. The people are irreligious and do not perform the sacrifices recommended in Bhagavad-gītā. Yajñād bhavati parjanyaḥ: [Bg. 3.14] by the performance of sacrifice, clouds form and rain falls. Due to sufficient rainfall, there is sufficient production of food. Guided by the brāhmaṇas, society should follow the principles of Bhagavad-gītā. Then people will become very happy. Annād bhavanti bhūtāni: when animals and man are sufficiently fed with grains, they become stronger, their hearts become tranquil and their brains peaceful. They can then advance in spiritual life, life's ultimate destination.
(Srimad Bhagavatam-----5:5:23-----purport).

Herein it is clearly indicated that a person who is not at all demoniac, such as Prahlāda Mahārāja and Bali Mahārāja, may outwardly be a demon or be born in a family of demons. Therefore in terms of real culture one should not be considered a demigod or demon simply according to birth. In his dealings while fighting with Indra, Vṛtrāsura proved himself a great devotee of the Supreme Personality of Godhead. Furthermore, as soon as he finished fighting with Indra and was apparently killed, Vṛtrāsura was transferred to Vaikuṇṭhaloka to become an associate of Saṅkarṣaṇa. Indra knew this, and therefore he was morose at having killed such a demon, who was actually a Vaiṣṇava or brāhmaṇa. A Vaiṣṇava is already a brāhmaṇa, although a brāhmaṇa may not be a Vaiṣṇava. The Padma Purāṇa says:
ṣaṭ-karma-nipuṇo vipro
mantra-tantra-viśāradaḥ
avaiṣṇavo gurur na syād
vaiṣṇavaḥ śva-paco guruḥ
One may be a brāhmaṇa in terms of his culture and family and may be expert in Vedic knowledge (mantra-tantra-viśāradaḥ), but if he is not a Vaiṣṇava, he cannot be a guru. This means that an expert brāhmaṇa may not be a Vaiṣṇava, but a Vaiṣṇava is already a brāhmaṇa. A millionaire may very easily possess hundreds and thousands of dollars, but a person with hundreds and thousands of dollars is not necessarily a millionaire. Vṛtrāsura was a perfect Vaiṣṇava, and therefore he was also a brāhmaṇa.
(Srimad Bhagavatam-----6:13:3-----purport).

Because of the increment in demoniac population, people have lost brahminical culture. Nor is there a kṣatriya government. Instead, the government is a democracy in which any śūdra can be voted into taking up the governmental reigns and capture the power to rule. Because of the poisonous effects of Kali-yuga, the śāstra (SB 12.2.13) says, dasyu-prāyeṣu rājasu: the government will adopt the policies of dasyus, or plunderers. Thus there will be no instructions from the brāhmaṇas, and even if there are brahminical instructions, there will be no kṣatriya rulers who can follow them. Aside from Satya-yuga, even formerly, in the days when demons were flourishing, Hiraṇyakaśipu planned to destroy the brahminical cultureand the kṣatriya government and thus create chaos all over the world. Although in Satya-yuga this plan was very difficult to execute, in Kali-yuga, which is full of śūdras and demons, thebrahminical culture is lost and can be revived only by the chanting of the mahā-mantra.
(Srimad Bhagavatam-----7:2:11-----purport).

Therefore the Vedic culture or brahminical culture teaches one how to be satisfied with possessing the minimum necessities in life. To teach this highest culture, varṇāśrama-dharma is recommended. The aim of the varṇāśrama divisions—brāhmaṇa, kṣatriya, vaiśya, śūdra, brahmacarya, gṛhastha, vānaprastha and sannyāsa—is to train one to control the senses and be content with the bare necessities. Here Lord Vāmanadeva, as an ideal brahmacārī, refuses Bali Mahārāja's offer to give Him anything He might want. He says that without contentment one could not be happy even if he possessed the property of the entire world or the entire universe. In human society, therefore, the brahminical culture, kṣatriya culture and vaiśya culture must be maintained, and people must be taught how to be satisfied with only what they need. In modern civilization there is no such education; everyone tries to possess more and more, and everyone is dissatisfied and unhappy. The Kṛṣṇa consciousness movement is therefore establishing various farms, especially in America, to show how to be happy and content with minimum necessities of life and to save time for self-realization, which one can very easily achieve by chanting the mahā-mantra—Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare.
(Srimad Bhagavatam-----8:9:21-----purport).

When the senses are engaged in devotional service to Hṛṣīkeśa, then the senses are completely satisfied. Without this superior knowledge of sense gratification, one may try to satisfy his material senses, but happiness will never be possible. One may increase his ambition for sense gratification and even achieve what he desires for the gratification of his senses, but because this is on the material platform, he will never achieve satisfaction and contentment. According to brahminical culture, one should be content with whatever he obtains without special endeavor and should cultivate spiritual consciousness. Then he will be happy. The purpose of the Kṛṣṇa consciousness movement is to spread this understanding. People who do not have scientific spiritual knowledge mistakenly think that the members of the Kṛṣṇa consciousness movement are escapists trying to avoid material activities. In fact, however, we are engaged in real activities for obtaining the ultimate happiness in life. If one is not trained to satisfy the spiritual senses and continues in material sense gratification, he will never obtain happiness that is eternal and blissful. Śrīmad-Bhāgavatam (5.5.1) therefore recommends:
tapo divyaṁ putrakā yena sattvaṁ
śuddhyed yasmād brahma-saukhyaṁ tv anantam
One must practice austerity so that his existential position will be purified and he will achieve unlimited blissful life.
(Srimad Bhagavatam-----8:19:24-----purport).

The Supreme Personality of Godhead generally appears in various types of incarnations to give protection to the cows and brāhmaṇas. The Lord is described as go-brāhmaṇa-hitāya ca; in other words, He is always eager to benefit the cows and brāhmaṇas. When Lord Kṛṣṇa appeared, He purposefully became a cowherd boy and showed personally how to give protection to the cows and calves. Similarly, He showed respect to Sudāmā Vipra, a real brāhmaṇa. From the Lord's personal activities, human society should learn how to give protection specifically to the brāhmaṇas and cows. Then the protection of religious principles, fulfillment of the aim of life and protection of Vedic knowledge can be achieved. Without protection of cows, brahminical culture cannot be maintained; and without brahminical culture, the aim of life cannot be fulfilled. The Lord, therefore, is described as go-brāhmaṇa-hitāya because His incarnation is only for the protection of the cows and brāhmaṇas. Unfortunately, because in Kali-yuga there is no protection of the cows and brahminical culture, everything is in a precarious position. If human society wants to be exalted, the leaders of society must follow the instructions of Bhagavad-gītā and give protection to the cows, the brāhmaṇas and brahminical culture.
(Srimad Bhagavatam-----8:24:5-----purport).

Those who are following in the footsteps of Śrī Caitanya Mahāprabhu should take the Lord’s mission most seriously. In this Age of Kali, people are gradually becoming less than animals. Nevertheless, although they are eating the flesh of cows and are envious of brahminical culture, Śrī Caitanya Mahāprabhu is considering how to deliver them from this horrible condition of life. Thus He asks all Indians to take up His mission:
bhārata-bhūmite haila manuṣya-janma yāra
janma sārthaka kari’ kara para-upakāra
“One who has taken his birth as a human being in the land of India [Bhārata-varṣa] should make his life successful and work for the benefit of all other people.” (Cc. Ādi-līlā 9.41) it is therefore the duty of every advanced and cultured Indian to take this cause very seriously. All Indians should help the Kṛṣṇa consciousness movement in its progress, to the best of their ability. Then they will be considered real followers of Śrī Caitanya Mahāprabhu. Unfortunately, even some so-called Vaiṣṇavas enviously refuse to cooperate with this movement but instead condemn it in so many ways. We are very sorry to say that these people try to find fault with us, being unnecessarily envious of our activities, although we are trying to the best of our ability to introduce the Kṛṣṇa consciousness movement directly into the countries of the yavanas and mlecchas. Such yavanas and mlecchas are coming to us and becoming purified Vaiṣṇavas who follow in the footsteps of Śrī Caitanya Mahāprabhu. One who identifies himself as a follower of Śrī Caitanya Mahāprabhu should feel like Śrī Caitanya Mahāprabhu, who said, ihā-sabāra kon mate ha-ibe nistāra: “How will all these yavanas be delivered?” Śrī Caitanya Mahāprabhu was always anxious to deliver the fallen souls because their fallen condition gave Him great unhappiness. That is the platform on which one can propagate the mission of Śrī Caitanya Mahāprabhu.
