Brahmins means the most intelligent class of men in the society, and kṣatriya means the administrative class of men, and vaiśyas means the mercantile class of men, and śūdra means the laborer class of men. That division is everywhere, not only in India. These four classes of men are present in every country, every society. It may be in different names only, but the four divisions are already there everywhere. It cannot be without it.
In the Bhagavad-gītā it is said, cātur-varṇyaṁ mayā sṛṣṭam (BG 4.13). These four classes of divisions are there according to different qualities, and Kṛṣṇa says, or God says: "That is My creation." So there cannot be any exception of His creation. Just like God's creation is sun. In every country there is sun, not that a sun can be seen in India. In every country there is moon. Similarly, this caste system is present in every country, in every society, but it may be called in different names.
So the śūdras means the lowest class of men, who have no culture. But the higher classes, the brahmins, the kṣatriyas, they are considered highly cultured. And how they are called highly cultured? Because they are twice-born. First birth, janmanā jāyate śūdraḥ saṁskārād bhaved dvijaḥ. Saṁskārāt, by following this ritualistic ceremony of initiation or marriage, they are called dvija, twice-born. Saṁskārād bhaved dvijo veda-pāthād bhaved vipraḥ.
This initiation means this boy is being accepted as initiated in order to give him Vedic instruction so that he may live as a student, as a brahmacārī, within this Society and (break) get complete instruction of Vedic knowledge. And when he is competent, he is called vipra. Veda-pāthād bhaved vipro brahma jānātīti brāhmaṇaḥ. And when he realizes the Supreme Self, the Supreme Personality of Godhead, he will be called brāhmaṇa . . . brahmin. At that time we offer thread ceremony.
So this process are there, we are observing, and our Kṛṣṇa consciousness movement is gradually making progress with these principles. We have got already eleven branches, and one of our principal student, Śrīman Hayagrīva Brahmacārī, and Kīrtanānanda Swami, they are attempting to open a new social community project in West Virginia, New Vrindaban. So this Kṛṣṇa conscious movement is taking ground gradually, and we hope in future these gṛhasthas, these householders, vānaprasthas, sannyāsīs, they will implement this Vedic culture gradually, and people will be more and more happy.
