krauṣṭukiruvāca
katidvīpāḥ samudrā vā parvatā vā kati dvija /
kiyanti caiva varṣāṇi teṣāṃ nadyaśca kā mune //

Krauṣṭuki spoke:
How many are the continents, and how many the oceans, and how many are the mountains, O brāhman? And how many are the countries, and what are their rivers, O Muni? And the size of the great objects of nature,[1] and the Lokāloka mountain-range; the circumference, and the size and the course of the moon and the sun also—tell me all this at length, O great Muni.
