Matsya Purana — Procedure for Going to Prayaga and the Greatness of the Ganga
सुवर्णालंकृतानां तु नारीणां लभते शतम् पृथिव्याम् आसमुद्रायां महाभूमिपतिर्भवेत् //
suvarṇālaṃkṛtānāṃ tu nārīṇāṃ labhate śatam pṛthivyām āsamudrāyāṃ mahābhūmipatirbhavet //
But he who obtains (or bestows) a hundred women adorned with gold becomes a great sovereign lord of the earth, his dominion extending up to the encircling seas.
This verse does not discuss pralaya; it is a dāna-phala statement describing worldly reward (sea-bounded sovereignty) arising from a specified act of gifting/obtaining.
It frames charity in royal/householder ethics: generous giving (dāna) is presented as a dharmic cause that yields political stability and kingship—teaching that prosperity and rule should be grounded in merit rather than mere force.
No Vāstu or temple-architecture rule is stated here; the ritual significance is the phalaśruti-style linkage between a prescribed dāna (gold-adorned gifts) and the attainment of vast earthly dominion.
