Matsya Purana — Solar–Lunar Motions
तथा शतसहस्राणां सप्तत्रिंशाधिकास्तु ताः इत्येतद्वै प्रसंख्यातं पृथिव्यन्तरमण्डलम् //
tathā śatasahasrāṇāṃ saptatriṃśādhikāstu tāḥ ityetadvai prasaṃkhyātaṃ pṛthivyantaramaṇḍalam //
Likewise, they are one hundred thousand, with thirty-seven more added. Thus is the inner terrestrial circle (the earth’s inner disc) precisely enumerated.
This verse is not about Pralaya; it belongs to cosmographical description, giving a numerical enumeration of the earth’s inner terrestrial circle.
Indirectly, it reflects the Purāṇic ideal of ordered knowledge (saṃkhyā/measurement) that supports righteous governance and planning, though the verse itself is a technical count, not a moral injunction.
The verse emphasizes precise enumeration and proportion—principles that also underpin Vāstu and ritual layout—though no specific temple or rite is named in this line.
