Matsya Purana — The Rite of the Vibhūti-Dvādaśī Vow
जन्मनां शतसाहस्रं न शोकफलभाग्भवेत् न च व्याधिर्भवेत्तस्य न दारिद्र्यं न बन्धनम् वैष्णवो वाथ शैवो वा भवेज्जन्मनि जन्मनि //
janmanāṃ śatasāhasraṃ na śokaphalabhāgbhavet na ca vyādhirbhavettasya na dāridryaṃ na bandhanam vaiṣṇavo vātha śaivo vā bhavejjanmani janmani //
For a hundred thousand births, one does not partake of the fruits of sorrow. Nor does disease befall that person—nor poverty, nor bondage. And in birth after birth, one becomes devoted either to Viṣṇu or to Śiva.
This verse does not address pralaya directly; it teaches karmic results (phala) of devotion—freedom from sorrow, illness, poverty, and bondage across many births.
It frames bhakti and dharmic observance as protective merit: a householder or king who upholds devotion and righteous conduct is promised relief from social and bodily afflictions (disease, poverty, imprisonment), reinforcing ethical living as practical as well as spiritual.
No Vāstu or temple-architecture rule is stated here; the ritual takeaway is the phala of sustained devotion—becoming consistently aligned with Vaiṣṇava or Śaiva worship in successive births.
