PURPORT

As stated in Bhagavad-gita (4.13), catur-varnyam maya srstam guna-karma-vibhagasah: the four divisions of human society were created by the Supreme Lord according to the three modes of material nature and the work ascribed to them. Formerly, the principle of dividing human society into four sections-brahmana, ksatriya, vaisya and sudra-was strictly followed, but because of gradual neglect of the varnasrama principles, varna-saṅkara population developed, and the entire institution has now been lost. In this age of Kali, practically everyone is a sudra (kalau sudra-sambhavah), and finding anyone who is a brahmana, ksatriya or vaisya is very difficult. Although the Krsna consciousness movement is a movement of brahmanas and Vaisnavas, it is trying to reestablish the divine varnasrama institution, for without this division of society there cannot be peace and prosperity anywhere.
