Sudra (SB cantos 7 - 9)
Srimad-Bhagavatam
SB Canto 7
On all the planets there are different types of residents, but the Lord recommends, referring especially to the planet earth, which is inhabited by human beings, that society be divided into four varṇas-brāhmaṇa, kṣatriya, vaiśya and śūdra. Before the advent of Lord Kṛṣṇa on this earth, it is understood that the earth was managed by the brāhmaṇas and kṣatriyas. The duty of the brāhmaṇas is to cultivate śamaḥ (peacefulness), damaḥ (self-control), titikṣā (tolerance), satyam (truthfulness), śaucam (cleanliness) and ārjavam (simplicity), and then to advise the kṣatriya kings how to rule the country or planet. Following the instructions of the brāhmaṇas, the kṣatriyas should engage the populace in austerity, sacrifices, Vedic study and adherence to the rules and regulations established by Vedic principles. They should also arrange for charity to be given to the brāhmaṇas, sannyāsīs and temples. This is the godly arrangement of brahminical culture.
