अधोलोकवर्णनम् (Adholoka-varṇana) — Description of the Lower Worlds and Cosmographic Measures
तथोदगयने सूर्यः सर्पते मन्दविक्रमः / तस्मा द्दीर्घेन कालेन भूमिं स्वल्पानि गच्छति
tathodagayane sūryaḥ sarpate mandavikramaḥ / tasmā ddīrghena kālena bhūmiṃ svalpāni gacchati
So too in the Udāgayana the Sun moves with gentle, slow stride; therefore, over a long span, he traverses the earth only little by little.
