यजुर्वेदशाखाः, याज्ञवल्क्य–वैशम्पायनसंवादः, सूर्यस्तुतिः
Yajurveda branches and Yājñavalkya’s solar revelation
यजूंष्य् अथ विसृष्टानि याज्ञवल्क्येन वै द्विज जगृहुस् तित्तिरीभूत्वा तैत्तिरीयास् तु ते ततः
yajūṃṣy atha visṛṣṭāni yājñavalkyena vai dvija jagṛhus tittirībhūtvā taittirīyās tu te tataḥ
随后,阎若婆迦所抛出的《夜柔》祭词被诸位二次生的圣者拾取;他们化作鹧鸪(tittirī)将其收集——因此自此被称为“泰帝利耶”(Taittirīya)。
Sage Parāśara (narrating to Maitreya)
This verse gives an etymological origin: sages gathered the discarded Yajus-mantras by becoming “tittirīs” (partridges), and thus the school became known as Taittirīya.
Through a narrative of recovery and transmission: even when mantras are “cast off,” qualified dvijas retrieve and preserve them, establishing an authoritative śākhā lineage.
Though Vishnu is not named in the verse, the Purāṇic frame treats stable Vedic transmission as part of dharma and cosmic order ultimately upheld by Vishnu as the Supreme sustaining reality.
