RV 1.164.3
इमं रथम् अधि ये सप्त तस्थुः सप्तचक्रं सप्त वहन्त्य् अश्वाः । सप्त स्वसारो अभि सं नवन्ते यत्र गवां निहिता सप्त नाम ॥
imaṃ ratham adhi ye sapta tasthuḥ saptacakraṃ sapta vahanty aśvāḥ | sapta svasāro abhi saṃ navante yatra gavāṃ nihitā sapta nāma ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
The seven who on the seven-wheeled car are mounted have horses, seven in tale, who draw them onward. Seven Sisters utter songs of praise together, in whom the names of the seven Cows are treasured.
Translated by Ralph T. H. Griffith (1896)
