Matsya Purana — The Madana-Dvādaśī Vow and the Birth of the Maruts
न तुषाङ्गारभस्मास्थिकपालेषु समाविशेत् वर्जयेत्कलहं लोकैर् गात्रभङ्गं तथैव च //
na tuṣāṅgārabhasmāsthikapāleṣu samāviśet varjayetkalahaṃ lokair gātrabhaṅgaṃ tathaiva ca //
One should not step into or come into contact with chaff, live embers, ashes, bones, or skulls. Likewise, one should avoid quarrelling with people and avoid bodily injury or mutilation.
It does not address Pralaya directly; it gives practical dharma-guidance on avoiding impure or inauspicious substances and maintaining social harmony.
It teaches restraint: avoid public quarrels and avoid causing or incurring bodily harm—key virtues for householders and especially rulers who must prevent conflict and protect bodies/lives.
The verse implies rules of ritual purity and auspicious space-management: areas contaminated by ashes, bones, or skulls are to be avoided, aligning with temple/ritual cleanliness norms often echoed in Vastu-oriented practice.
