The word yavana means “meat-eater.” Anyone from a meat-eating community is called a yavana. One who does not strictly observe the Vedic regulative principles is called a mleccha. These words do not refer to any particular man. Even if a person is born in a brāhmaṇa, kṣatriya, vaiśya or śūdra family, he is a mleccha or yavana if he does not strictly follow the regulative principles or if he eats meat.
