"[a homeland decidedly east of the Punjab] is supported even by native traditions. At a very early (Brahmanic) period the Northerners‘ are regarded as a suspicious sort of people, whose religious practices, far from being authoritative, are censured. No tradition associates the ancient literature with the Punjāb. In fact, save for one exception, even the legal manuals do not take cognizance of the Northwest. They have the stanza that defines Āryāvarta, and also the stanzas that extend the geographical boundary still further south; but they ignore the North."
