Matsya Purana — The Greatness of the Vibhūti-Dvādaśī Vow: Pushkara
तस्मात्किमन्यजननीजठरोद्भवेन धर्मादिकं कृतमशेषफलाप्तिहेतुः भगवन्मयाथ तनयैर् अथवानयापि भद्रं यदेतदखिलं कथय प्रचेतः //
tasmātkimanyajananījaṭharodbhavena dharmādikaṃ kṛtamaśeṣaphalāptihetuḥ bhagavanmayātha tanayair athavānayāpi bhadraṃ yadetadakhilaṃ kathaya pracetaḥ //
Therefore, what further need is there to be born again from another mother’s womb? O Blessed Lord—if the practice of dharma and related duties is the cause of attaining every fruit—then tell me fully, O Pracetas, what is truly auspicious, whether it should be done by me, by my sons, or even by her (my wife) as well.
This verse does not describe pralaya directly; it emphasizes escaping repeated birth (rebirth from a womb) through the complete practice of dharma that yields “all results,” implying a soteriological aim rather than a cosmological event.
It frames dharma as a comprehensive, results-bearing discipline to be practiced not only by the ruler (Manu) but also by his sons and wife—highlighting family-wide responsibility in vows, rites, charity, and ethical conduct central to householder and royal life.
No explicit Vastu or temple-architecture rule appears here; the ritual significance is general—dharma “and allied duties” (rites/vows) are presented as the means to secure auspicious welfare and complete fruition.
