In Vedic literature there are names like mleccha and yavana. The mlecchas are understood to be those who do not follow the Vedic principles. In former days, the mlecchas were fewer, and Viśvāmitra Muni cursed his sons to become mlecchas. But in the present age, Kali-yuga, there is no need of cursing, for people are automatically mlecchas. This is only the beginning of Kali-yuga, but at the end of Kali-yuga the entire population will consist of mlecchas because no one will follow the Vedic principles. At that time the incarnation Kalki will appear. Mleccha-nivaha-nidhane kalayasi karavālam. He will kill all the mlecchas indiscriminately with his sword.
