 This meaning is worked into the account of the stated origin of the School of Tittri in the Vishnu Purana (Book 3, Chapter 5).Following a division between Brahmins at Mount Meru - including Vaiśampáyana (whose pupil, Tittiri, is attributed to the Krishna (black) Yajurveda) and Yajnavalkya (attributed to the Shukla (White) Yajurveda) - 'The other scholars of Vaiśampáyana, transforming themselves to partridges (Tittiri), picked up the texts which he [Yájnawalkya] had disgorged, and which from that circumstance were called Taittiríya'.This indicates both Yaska and Taittiri were pupils of Vaiśampáyana.
