The Rig Veda describes the Rigvedic people as 'Aryas', distinguishing them from 'Dasyus', implying a cultural identity. The linguistic and religious similarities between the Rig Veda and the Avesta are well-established, pointing to a common Indo-Iranian origin. The goddess Saraswati is highly praised in the Rig Veda and referred to as 'naditama' (best of rivers).
