"Vedic civilization acknowledges among its greatest spokesmen members of "backward" communities such as the Mahabharata's author Vyasa, the Ramayana's author Valmiki or the Tamil poet Tiruvalluvar. Its understanding of "Arya" is not as a racial nor even a linguistic term, but as a cultural term, a synonym for "Vedic", neither more nor less."
