Cātur-varṇyaṁ mayā sṛṣṭaṁ guṇa-karma-vibhāgaśaḥ (BG 4.13). Kṛṣṇa has divided the society, human society, in four divisions: the brāhmaṇa, the kṣatriya, the vaiśya, the śūdras. These divisions of the human society must be there. If there is no intelligent person, brāhmaṇa, simply śūdras, you cannot be happy. That is not possible. Just like to keep your body, there must be head, there must be arms, there must be belly and there must be leg. Simply if you have got legs, that is dead body. Even simply you have got head, that is also dead body. Four things must be there. How you can violate this? "No, no, we don't require head" or "don't require leg." No, no. Kṛṣṇa says, "No." Cātur-varṇyaṁ mayā sṛṣṭam (BG 4.13). "This is My regulative principle. I give you." Just maintain a first-class, intelligent man. Don't disturb them. Give them all facilities. Let them cultivate Vedic knowledge and help you. That is required.
