Matsya Purana — The Madana-Dvādaśī Vow and the Birth of the Maruts
न वस्त्रहीना नोद्विग्ना न चार्द्रचरणा सती नामङ्गल्यां वदेद्वाचं न च हास्याधिका भवेत् //
na vastrahīnā nodvignā na cārdracaraṇā satī nāmaṅgalyāṃ vadedvācaṃ na ca hāsyādhikā bhavet //
A virtuous woman should not be without proper clothing, nor remain agitated; she should not go about with wet feet. She should not utter inauspicious words, and she should not indulge in excessive laughter.
This verse does not address pralaya or cosmology; it focuses on auspicious daily conduct (sadācāra) and self-restraint in speech and demeanor.
It supports householder-dharma by prescribing auspicious, orderly behavior within the home—composure, cleanliness, and restrained speech—values that a king is also expected to promote as social discipline.
No direct Vāstu or temple-building rule is stated; however, the emphasis on auspiciousness (maṅgala) and purity (e.g., not moving about with wet feet) aligns with broader ritual notions of śauca and proper conduct in sacred or domestic spaces.
