Matsya Purana — Mahāgaurī’s Entry
जगति कः प्रणताभिमतं ददौ झटिति सिद्धनुते भवती यथा जगति कां च न वाञ्छति शंकरो भुवनधृत्तनये भवतीं यथा //
jagati kaḥ praṇatābhimataṃ dadau jhaṭiti siddhanute bhavatī yathā jagati kāṃ ca na vāñchati śaṃkaro bhuvanadhṛttanaye bhavatīṃ yathā //
In this world, who else grants—instantly—the desired boon of those who bow in reverence, as you do, O bestower of success? And in this world, whom does Śaṅkara not desire—just as he desires you, O daughter of Bhūvanadhṛt (the Earth)?
This verse is devotional rather than cosmological; it emphasizes the Goddess’s swift boon-giving power and Śiva’s singular devotion, not pralaya or creation mechanics.
Indirectly, it models the Purāṇic ethic of humility and surrender (praṇati): rulers and householders are taught to seek success through reverence, self-restraint, and devotion rather than pride.
No explicit Vāstu or iconographic rule is stated; the ritual takeaway is stuti as a devotional practice—praising the Goddess as the giver of siddhi (attainment) and desired boons.
