4.13.24

etad ākhyāhi me brahman sunīthātmaja-ceṣṭitam /
śraddadhānāya bhaktāya tvaṃ parāvara-vittamaḥ //

24. O holy sage explain the history of Sunīthā's son (Vena), to me who is full of faith and devotion to thee, and thou art foremost among those that know Para and Avara (all things from Brahman down to the simplest thing).
