Srimad-Bhagavatam

SB Canto 7

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.

SB 7.2.10, Translation and Purport: While I am engaged in the business of killing Lord Viṣṇu, go down to the planet earth, which is flourishing due to brahminical culture and a kṣatriya government. These people engage in austerity, sacrifice, Vedic study, regulative vows, and charity. Destroy all the people thus engaged!

Hiraṇyakaśipu's main purpose was to disturb the demigods. He planned first to kill Lord Viṣṇu so that with Lord Viṣṇu's death the demigods would automatically weaken and die. Another of his plans was to disturb the residents of the planet earth. The peace and prosperity of the residents of earth, and all the other planets, were maintained by the brāhmaṇas and kṣatriyas. The Lord says in Bhagavad-gītā (4.13), cātur-varṇyaṁ mayā sṛṣṭaṁ guṇa-karma-vibhāgaśaḥ: "According to the three modes of material nature and the work ascribed to them, the four divisions of human society were created by Me." 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.
