Matsya Purana — The Aśūnyaśayana Vrata
लक्ष्म्या वियुज्यते देव न कदाचिद्यथा भवान् तथा कलत्रसम्बन्धो देव मा मे वियुज्यताम् //
lakṣmyā viyujyate deva na kadācidyathā bhavān tathā kalatrasambandho deva mā me viyujyatām //
O Lord, just as You are never, at any time, separated from Lakṣmī, so too—O God—may my bond with my spouse never be severed.
This verse does not discuss pralaya or cosmology; it is a devotional petition using the model of Viṣṇu’s inseparability from Lakṣmī to seek steadiness in one’s own life.
It aligns with gṛhastha-dharma by valuing stability, fidelity, and continuity of the marital bond—seen as a foundation for household order, prosperity, and ethical living.
No Vāstu or temple-architecture rule is stated; the ritual significance is stotra-style prayer within a vrata context, where invoking Lakṣmī-Nārāyaṇa is linked to auspiciousness and domestic well-being.
