Śrīmad-Bhāgavatam · Text 4.16.14
Who is speaking and story frame
अस्याप्रतिहतं चक्रं पृथोरामानसाचलात् । वर्तते भगवानर्को यावत्तपति गोगणै: ॥ १४ ॥
asyāpratihataṁ cakraṁ
pṛthor āmānasācalāt
vartate bhagavān arko
yāvat tapati go-gaṇaiḥ
Just as the sun-god expands his shining rays up to the Arctic region without impedance, the influence of King Pṛthu will cover all tracts of land up to the Arctic region and will remain undisturbed as long as he lives.
