Aryavarta (Sk.). The “land of the Aryas”, or India. The ancient name for Northern India. The Brahmanical invaders (“ from the Oxus” say the Orientalists) first settled. It is erroneous to give this name to the whole,of India, since Manu gives the name of “the land of the Aryas” only to “the tract between the Himalaya and the Vindhya ranges, from the eastern to the western sea”.
