Matsya Purana — Yadu Lineage
एवमुक्ताब्रवीद् एनं भज भक्तान्महाव्रत एष धर्मः सतां ब्रह्मन् न धर्मं लोपयामि ते //
evamuktābravīd enaṃ bhaja bhaktānmahāvrata eṣa dharmaḥ satāṃ brahman na dharmaṃ lopayāmi te //
Having spoken thus, she said to him: “Honor and serve the devotees (bhaktas), O great observer of vows. This is the dharma of the good, O Brahmin; I will not allow your dharma to be diminished.”
This verse does not address pralaya directly; it emphasizes ethical continuity—protecting dharma through honoring devotees and maintaining righteous vows.
It frames a core duty of social and personal governance: uphold sat-dharma by respecting and supporting devotees and the righteous, thereby preventing the decline of one’s own dharma and vows.
No explicit Vastu or temple-construction rule appears here; the ritual takeaway is devotional ethics—bhakta-seva as a meritorious practice that safeguards dharma.
