स यावदादित्यः पश्चादुदेता पुरस्तादस्तमेता द्विस्तावदुत्तरत उदेता दक्षिणतोऽस्तमेता मरुतामेव तावदाधिपत्य्ंस्वाराज्यं पर्येता ॥ ३.९.४ ॥
In plain words
Twice as long as the sun rises in the west and sets in the east, it rises in the north and sets in the south; and for that long does he attain the sovereignty and self-rule of the Maruts.
