परस्परेण द्विगुणा: सर्वे द्वीपा नराधिप । पर्वताश्न महाराज समुद्रै: परिवारिता:,महाराज! इन समुद्रोंसे घिरे हुए सभी द्वीप और पर्वत उत्तरोत्तर दुगुने विस्तारवाले हैं
paraspareṇa dviguṇāḥ sarve dvīpā narādhipa | parvatāś ca mahārāja samudraiḥ parivāritāḥ ||
Sañjaya said: “O lord of men, O great king, all the islands are each successively twice as extensive as the previous, and the mountains too—each encircled by the surrounding seas.”
संजय उवाच
The verse presents the world as an ordered system where each region is proportionate and bounded—each dvīpa and its features are defined in relation to others and enclosed by seas. Implicitly, it places human affairs (including war) within a vast, structured cosmos, encouraging humility and a sense of limits.
Sañjaya is describing cosmographical details to the king (Dhṛtarāṣṭra), stating that the islands/continents and mountains increase successively in size, and that each is surrounded by oceans.
