Matsya Purana — Division of Bhārata-varṣa
न खल्वन्यत्र मर्त्यानां भूमौ कर्मविधिः स्मृतः भारतस्यास्य वर्षस्य नव भेदान्निबोधत //
na khalvanyatra martyānāṃ bhūmau karmavidhiḥ smṛtaḥ bhāratasyāsya varṣasya nava bhedānnibodhata //
Indeed, nowhere else on earth is the ordained rule of action (karma and its rites) for mortals recognized as it is here. Therefore, understand the nine divisions of this Bhārata-varṣa.
This verse is not about Pralaya; it emphasizes sacred geography—Bhārata-varṣa is singled out as the land where karma-vidhi (ritual and moral law governing actions) is especially operative for humans.
By declaring Bhārata-varṣa the primary karmabhūmi, it frames kings and householders as responsible for upholding karma-vidhi—Vedic rites, social duties, and dharmic governance—since this land is presented as uniquely suited for structured religious action and merit.
Ritually, it highlights karma-vidhi—prescribed procedures for dharma and yajña—implying that correct ritual performance is central in Bhārata-varṣa; no direct Vastu or temple-architecture rule is stated in this verse.
