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. This is called second birth. Saṁskārād bhaved dvijaḥ. Saṁskāra means purificatory process. So that is human life, not that to beget a child. That begetting is going on by the cats and dogs. That is not . . . that is first birth. Janmanā jāyate śūdraḥ. So that kind of birth is accepted as śūdra. Then he can be trained up.
A śūdra, actually those who are by qualification śūdra . . . śūdra means lamentation, simply changing. They accept something, and then they find it's 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 titikṣa 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. Yes.
Brāhmaṇa, they are teachers, natural teachers, and there is no fees. No fees. Just like we started this Kṛṣṇa consciousness movement, teaching, but there was no fees. This is the teaching, real teaching. So brāhmaṇa should not charge anything, but they can take charity. So the students, they would bring charities naturally. This was brāhmaṇa's profession. They would not charge anything, but his disciples, students, would beg from door to door and bring. That is gurukula. Gurukula. Gurukula means every student should go to gurukula and learn to become very simple and obedient and self-controlled and learn how to address every woman as mother. This is guru . . . from the very beginning. They would go every home. Small children or big children, they will address, "Mother, give us some alms." So every woman will give, and they would bring it to guru. And that is guru's property. Not because he has begged this thing from somebody, it has become his property. No. It is guru's property. This is called brahmacārī gurukula. It gives one the training.
