तस्यां हिमवत्समुद्रान्तरमुदीचीनं योजनसहस्रपरिमाणं तिर्यक्चक्रवर्तिक्षेत्रम् ॥ कZ_०९.१.१८ ॥
tasyāṃ himavat-samudrāntaram udīcīnaṃ yojana-sahasra-parimāṇaṃ tiryak cakravarti-kṣetram
Within it, the northern tract between the Himavat and the ocean—measuring a thousand yojanas across—is the transverse field of the universal sovereign (cakravartin).
It sets an idealized strategic theatre for assessing expansion, logistics, frontier management, and comparative power across a large contiguous region.
It functions primarily as a standardized spatial claim for strategic reasoning; exact modern equivalence varies by tradition and is less central than the comparative scale.
