ChU 3.9.4
स यावद् आदित्यः पश्चाद् उदेता पुरस्ताद् अस्तम् एता द्विस् तावद् उत्तरत उदेता दक्षिणतो ऽस्तम् एता मरुताम् एव तावद् आधिपत्यं स्वाराज्यं पर्येता
sa yāvad ādityaḥ paścād udetā purastād astam etā dvis tāvad uttarata udetā dakṣiṇato 'stam etā marutām eva tāvad ādhipatyaṃ svārājyaṃ paryetā
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
So long as the sun rises in the west and sets in the east, twice as long does it rise in the north and set in the south; and so long does he follow the sovereign supremacy of the Maruts.
Translated by F. Max Müller
