Vishnupurana 2.8.85-89

On the north of Agastya, and south of the line of the Goat, exterior to the Vaiswánara path, lies the road of the Pitris. There dwell the great Rishis, the offerers of oblations with fire, reverencing the Vedas, after whose injunctions creation commenced, and who were discharging the duties of ministrant priests: for as the worlds are destroyed and renewed, they institute new rules of conduct, and reestablish the interrupted ritual of the Vedas. Mutually descending from each other, progenitor springing from descendant, and descendant from progenitor, in the alternating succession of births, they repeatedly appear in different housed and races along with their posterity, devout practices and instituted observances, residing to the south of the solar orb, as long as the moon and stars endure.
