RV 3.30.12
दिशः सूर्यो न मिनाति प्रदिष्टा दिवे-दिवे हर्यश्वप्रसूताः । सं यद् आनळ् अध्वन आद् इद् अश्वैर् विमोचनं कृणुते तत् त्व् अस्य ॥
diśaḥ sūryo na mināti pradiṣṭā dive-dive haryaśvaprasūtāḥ | saṃ yad ānaḷ adhvana ād id aśvair vimocanaṃ kṛṇute tat tv asya ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Surya transgresses not the ordered limits set daily by the Lord of Tawny Coursers. When to the goal he comes, his journey ended, his Steeds he looses: this is Indra's doing.
Translated by Ralph T. H. Griffith (1896)
