अधोलोकवर्णनम् (Adholoka-varṇana) — Description of the Lower Worlds and Cosmographic Measures
कुलालचक्रनाभिश्च यथा तत्रैव वर्त्तते / ध्रुवस्तथा हि विज्ञेयस्तत्रैव परीवर्त्तते
kulālacakranābhiśca yathā tatraiva varttate / dhruvastathā hi vijñeyastatraiva parīvarttate
As the hub of a potter’s wheel remains right there, so should Dhruva be understood: he turns about, yet abides in that very place.
