यजुर्वेदशाखाः, याज्ञवल्क्य–वैशम्पायनसंवादः, सूर्यस्तुतिः
Yajurveda branches and Yājñavalkya’s solar revelation
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
O best of the twice-born, the Brahmins who mastered those Yajus hymns came to be known as Vājinas, for from that very cause the Sun became the Horse.
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.
