Vishnupurana 1.1.29

1.1.29

iti pūrvaṃ vasiṣṭhena pulastyena ca dhīmatā
yad uktaṃ tat smṛtiṃ yātaṃ tvatpraśnād akhilaṃ mama //

Now truly all that was told me formerly by Vaśisht́ha, and by the wise Palastya, has been brought to my recollection by your questions, and I will relate to you the whole, even all you have asked. Listen to the complete compendium of the Pur pas, according to its tenour. The world was produced from Vishńu: it exists in him: he is the cause of its continuance and cessation: he is the world.
