RV 10.44.2
सुष्ठामा रथः सुयमा हरी ते मिम्यक्ष वज्रो नृपते गभस्तौ । शीभं राजन् सुपथा याह्य् अर्वाङ् वर्धाम ते पपुषो वृष्ण्यानि ॥
suṣṭhāmā rathaḥ suyamā harī te mimyakṣa vajro nṛpate gabhastau | śībhaṃ rājan supathā yāhy arvāṅ vardhāma te papuṣo vṛṣṇyāni ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Firm-seated is thy car, thy Steeds are docile; thy hand, O King, holds, firmly grasped, the thunder. On thy fair path, O Lord of men, come quickly: we will increase thy powers when thou hast drunken.
Translated by Ralph T. H. Griffith (1896)
