यजूंषि यैर् अधीतानि तानि विप्रैर् द्विजोत्तम वाजिनस् ते समाख्याताः सूर्यो ऽश्वः सो ऽभवद् यतः
yajūṃṣi yair adhītāni tāni viprair dvijottama vājinas te samākhyātāḥ sūryo 'śvaḥ so 'bhavad yataḥ
¡Oh el mejor de los nacidos dos veces! Los brahmanes que estudiaron esos himnos del Yajus fueron llamados Vājinas, pues de ese mismo origen el Sol se hizo Caballo.
Sage Parāśara (speaking to Maitreya)
Speaker: Parasara
Topic: Why the Vājasaneyins are called Vājinas; the horse-form of Sūrya as origin marker
Teaching: Historical
Quality: authoritative
It is presented as a traditional designation for Brahmins associated with the study of the Yajus, explained through a mythic-etymological link to the Sun’s horse-form (swift, life-bearing solar power).
He uses narrative etymology: groups are named according to an originating symbol or event—here, the Yajus-students are called Vājinas because of the associated emergence of the Sun as the Horse.
The verse situates Vedic learning and solar order within a Purāṇic cosmos ultimately governed by the Supreme Reality—Vishnu—whose sovereignty underwrites the regularity of the Sun and the authority of Vedic revelation.
