Bhagavatapurana 10.87.10

10.87.10

śvetadvīpaṃ gatavati tvayi draṣṭuṃ tad-īśvaram /
brahma-vādaḥ su-saṃvṛttaḥ śrutayo yatra śerate /
tatra hāyam abhūt praśnas tvaṃ māṃ yam anupṛcchasi //

10. When thou wast at Svetadvipa to see the Lord there, a Vedic discussion took place, in which all the Srutis were passed in review and co-ordinated and in that discussion was started this very question which thou hast put Me.
