This is Kṛṣṇa's words in the Bhagavad-gītā. If you actually become Kṛṣṇa conscious, the result will be you'll get special favor from Kṛṣṇa. Teṣām eva anukampārtham. Kṛṣṇa is specially favorable to the devotees. Ye tu bhajanti māṁ prītyā. Therefore this is the beginning. This is the beginning of . . .
Caitanya Mahāprabhu also accepted this. Sthāne sthitaḥ śruti-gataṁ tanu-vāṅ-manobhiḥ. Jñāne prayāsam udapāsya namanta eva (SB 10.14.3). We have to be submissive, not a speculator, that "Now I have become Brahman." Brahman, everyone is Brahman. There is no question of becoming Brahman. We have now forgotten. We have forgotten that we are Brahman. We are misidentifying with this body. This is māyā. Otherwise . . . therefore Bhagavad-gītā says, brahma-bhūtaḥ prasannātmā (BG 18.54). It is not that by some process I become Brahman. I am Brahman, but on account of māyā, my knowledge is covered. I am thinking, "I am product of this material world," "I am American," "I am Indian," in terms of the soil where we have taken birth. Yasyātmā-buddhiḥ kuṇape tri-dhātuke sva-dhīḥ kalatrādiṣu bhauma ijya-dhīḥ (SB 10.84.13). Bhauma ijya-dhīḥ. The whole world is mad after this process of bhauma ijya-dhīḥ. They are . . . instead of worshiping Kṛṣṇa, they are worshiping the land in which one is born. That is called under the name of, going on, so many "isms." So this is described as bhauma ijya-dhīḥ.
But actually, we are part and parcel of Kṛṣṇa. Kṛṣṇa is Para-brahman; therefore we, being part and parcel, we are also Brahman. Just like particles of gold is also gold. So there is no question of becoming Brahman. Brahman we are already. Simply we have to know that "I am not this body." Ahaṁ brahmāsmi: "I am spirit soul, part and parcel of Kṛṣṇa." That is knowledge. Jñānaṁ jñeyam. Jñeyam, this knowledge, that "I am Brahman." And as soon as we are perfectly situated in that spiritual knowledge, aham brahmāsmi, then brahma-bhūtaḥ prasannātmā na śocati na kāṅkṣati (BG 18.54). There is no lamentation.
Everyone is lamenting, because he's a śūdra. Śūdra's business is to lament. But when one understands, brāhmaṇa, brahma jānātīti brāhmaṇaḥ, he does not lament. We have seen many brāhmaṇas, they are not very materially opulent, but they are happy. They are happy with Kṛṣṇa. That is brāhmaṇa's business. Brāhmaṇa-vaiṣṇava. Brāhmaṇa must be a Vaiṣṇava, Kṛṣṇa conscious. If a brāhmaṇa is not Vaiṣṇava, then he cannot become guru. That is the injunction of the śāstra. Ṣaṭ-karma-nipuṇo vipro mantra-tantra-viśāradaḥ (Padma Purāṇa). A vipra, a brāhmaṇa, a learned . . . vipra means a learned brāhmaṇa. Veda-pāṭhād bhaved vipraḥ. One who has learned, studied all the Vedic literatures and has acquired knowledge, he is called vipra. So simply studying Vedic literature will not do. Brahma jānātīti brāhmaṇaḥ. He must realize what is Brahman. Then he becomes brāhmaṇa.
Brāhmaṇa is a qualification. It is not by birth. Brāhmaṇa . . . just like high-court judge is a qualification. It is not by birth. The high-court judge's son is not a high-court judge unless he has the qualification of a high-court judge. Similarly, a son of a brāhmaṇa by birth is not a brāhmaṇa. When he has got the brahminical qualification, then he becomes brāhmaṇa. That qualification are stated in the Bhagavad-gītā. It is not imagination. Śamo damas titikṣavo 'rjavam, jñānaṁ vijñānam āstikyaṁ brahma-karma svabhāva-jam (BG 18.42).
