True brahmana status requires both qualification and consistent conduct—knowledge without practice remains spiritually useless.Listen — Srila Prabhupada Uvaca
Prabhupāda: [leads devotees in chanting] kānyakubje dvijaḥ kaścid dāsī-patir ajāmilaḥ nāmnā naṣṭa-sadācāro dāsyāḥ saṁsarga-dūṣitaḥ [SB 6.1.21] [01:32] So yesterday Śukadeva Gosvāmī said, "In this connection I shall cite the example, historical example, of Ajāmila." So historical reference. It is not fiction, because Kānyakubja is still there. The city of Kānyakubja is still existing there, and the Bhāgavata was written five thousand years ago. So that means the city existed before five thousand.
Kānyakubje. Kānyakubje dvijaḥ. Dvija means twice-born. First-born by the father and mother, and the next birth is dvijaḥ, means by the father, spiritual master, and the mother, Vedic knowledge.

They accept something, and then they find it useless, and they lament. The so-called scientists, philosophers, they're all śūdras because they say, "We have discovered something," and after few years, "Oh, it is now useless.
Another theory." Śūdra. So śūdra cannot give you any education. That is not possible. Education has to be taken from brāhmaṇa.
That is Vedic system. Brāhmaṇa is the teacher because they are trained up—satya śama damo titikṣā ārjavam, jñānaṁ vijñānam āstikyaṁ brahma-karma-svabhāva-jam [Bg 18.42]. Therefore in India still, not in the city but in the village, the brāhmaṇa is accepted as teacher, natural teacher. And there was... [aside:] You sit down properly.
